O2 Business review: Strong on value and international roaming

  • Barry Collins

O2 Business review

Strong roaming offering, but a middling performance otherwise

  • Good value for money on SIM-only
  • Free EU roaming
  • Dissatisfaction with coverage
  • Roaming is pricey outside the EU

Now happily married to Virgin Media, O2 has a long pedigree in the mobile business, dating all the way back to the turn of the century when it was BT Cellnet. In that time, millions of businesses have entrusted their mobile connections to the company, but why should they do so in 2023?

One answer might be value for money. With 80% of customers we surveyed reporting being satisfied with the value they’re getting, O2 secures a Highly Commended award for value in the Expert Reviews Business Mobile Network Awards 2023. And you can begin to understand why when you see that its SIM-only business tariffs start from as little as £10/mth.

O2 posted respectable scores right across the board, but if it wants to climb above Vodafone and EE in our rankings then it has work to do in two areas that are critical for business customers: coverage and reliability. Of the four major networks, O2 had the biggest proportion of customers that were dissatisfied with their coverage by far – more than double the percentage of the next worst provider, in fact.

However, if we assume you’re in an area that has decent coverage, let’s explore what O2 has to offer.

Fill in our quick survey below and we’ll provide quotes for business mobile contracts that match your requirements.

O2 Business review: What do you get?

With deals starting at just £10/mth, O2’s cheapest SIM-only tariff is £5/mth less than the table-topping EE. That said, it only affords you a mere 1GB of data, so it would be best suited to business customers who want unlimited calls and texts, and not those who spend all day on Zoom calls.

In general, O2’s SIM-only deals are competitively priced, with 100GB of data for £18/mth being a particularly eye-catching deal. However, the deals on popular handsets such as the iPhone 14 and Galaxy S23 are less keenly priced, with rivals offering them with more data at cheaper prices. If you’re determined to stay with O2, it might be worth showing the sales staff the prices that are on offer from other networks – such as EE, for example – and seeing if O2 will match them.

O2 should be commended for the simplicity of its tariffs, with a decent span of data allowances. The company also offers data-only tariffs for businesses looking to give other devices, such as laptops or tablets, mobile connectivity.

It’s also worth noting that O2 offers data rollover on many tariffs, so if you don’t use your full data allowance one month the remainder is carried over to the next.

(* O2 offers data-only SIMs at a slightly cheaper price)

O2 Business review: Customer service

According to our survey, O2’s customer service is just below average for the industry. Although a very respectable 87% of O2 customers are satisfied with the service, that’s still a worse score than both Vodafone (88%) and EE (93%).

Our survey data roughly reflects that of the regulator, Ofcom, whose latest report says that O2 registers four complaints per 100,000 customers, which is above the industry average of three.

O2 Business review: Coverage, reliability and speed

As we mentioned earlier, coverage remains a sore point, at least for the O2 customers we surveyed, with 7.5% of its customers saying they were dissatisfied with the coverage – more than double the level of unhappiness reported at the next worst provider, Three (3.3%).

Coverage and reliability are inextricably linked and here, again, O2 fares relatively poorly with 5.3% reporting that they were unhappy with the network’s reliability. This was the worst score of the four major networks in our test, though, in fairness, it should also be stated that 85% were satisfied.

When it comes to speed, 85% of O2 customers are happy with their lot, which is about average for the four networks.

O2 Business review: Roaming

Roaming is blissfully simple on O2 – at least if you’re travelling in the EU, where you get to use your minutes, texts and data as if you were still back in Blighty. The only exception is if you’re on an unlimited data plan, as you’ll be limited to 35GB while abroad, though this is still a very generous allocation in our view.

Things do get more expensive if you’re travelling outside of Europe. Here, O2 offers Rest of the World 24-Hour Passes, which cost £7.50 per day for 500MB of data, 300 minutes and 300 texts in 96 different destinations. If you’re travelling outside of Europe for long periods, it might make more sense to look for a local SIM than use your O2 contract.

While we’re talking all things international, it’s not roaming, but on selected O2 Small Biz tariffs you do get some inclusive call minutes and texts when placing calls from the UK to the EU. That could prove handy if your business has clients abroad.

O2 Business review: Extras

We mentioned the data rollover above, which is a nice touch if you don’t use all of your monthly data allowance, and might even mean you can stick to a cheaper tariff since the rollover might bail you out on the select months when your data usage is high.

All tariffs also come with free O2 Wi-Fi, which is likely to come in useful at public venues such as cafes and train stations.

O2 Business review: Verdict

O2 puts in a very middle-of-the-road performance in our survey. Gripes about coverage aside, it’s not terrible at anything, but it doesn’t excel in any category either. That said, free EU roaming and other international calling benefits might help business owners with international clients.

O2 international roaming FAQ

archie burkinshaw author image

Staying connected while travelling abroad can be tricky and often costly. However, O2 has one of the most extensive international roaming policies of the UK's major networks – helping them to make the most of their mobile services while overseas.

EU roaming without charges

One of the standout features of O2's international roaming policy is its commitment to providing EU roaming without additional charges. Currently, O2 is the only major network operator that has continued to offer EU roaming without fees for data, calls, and texts up to 25GB. This means customers can use their mobile phones just like they would in the UK when travelling to any of the 48 destinations within O2's Europe Zone.

Those 48 destinations are:

Canary Islands

Czech Republic

French Guiana

Isle of Man

Liechtenstein

Netherlands

Saint Barthelemy

Saint Martin

Switzerland

United Kingdom

Vatican City

O2 Fair Usage Limit

To ensure international roaming remains fair for all users, O2 has implemented a Fair Usage Limit (FUP). This limit is designed to prevent continuous and excessive use of services outside the UK in its Europe Zone. 

Customers can use O2's services for periodic travel, such as holidays or short breaks. However, if you use O2’s services outside the UK in the Europe Zone for 63 or more days within any four-month period – and cannot demonstrate significant use or presence in the UK – charges may apply after two weeks. The charges for Pay Monthly customers include £3.50/GB for data, 3.3p/minute for calls, and 1p/text.

Roaming limits for O2 tariffs

The roaming limits differ based on the customer's monthly data allowance:

Tariffs with more than 25GB of monthly data: Customers with a UK monthly data allowance exceeding 25GB will have a roaming limit of 25GB within the Europe Zone. Once the limit is reached, customers can still use data, but they will be charged £3.50 per additional gigabyte until they return to the UK, use up their UK data allowance, or reach their next bill cycle.

Tariffs with 25GB or less of monthly data: These tariffs are not subject to the 25GB roaming limit within the Europe Zone. However, customers who exhaust their UK data allowance while roaming abroad will need to purchase a data Bolt On to continue using data. 

What's included and not included

O2's international roaming policy includes making calls and sending texts within the Europe Zone (excluding the UK), receiving calls and texts in the Europe Zone, and using your monthly data allowance while in the Europe Zone. 

However, it does not include making calls or sending texts from the UK to countries outside of the UK, making calls or sending texts to premium rate numbers, directory service numbers, and some non-geographic numbers. 

Additionally, mobile broadband tariffs are only valid for use within the UK, and mobile data usage while on a cruise ship is subject to separate charges.

O2 Travel Inclusive Zone and O2 Travel Bolt On

For travellers seeking even more extensive coverage and flexibility, O2 offers a couple of options:

1. O2 Travel Inclusive Zone

If you have a O2 Travel Inclusive Zone included in your tariff, you're in luck. This feature provides you with unlimited minutes, texts, and data roaming privileges in 27 destinations worldwide. Among the covered locations are popular destinations like the USA, Australia, and New Zealand, ensuring that you stay connected without worry during your international adventures. The full list of destinations included in the O2 Travel Inclusive Zone can be found here.  

2. O2 Travel Bolt On

If O2 Travel Inclusive Zone isn't part of your current plan you can still enjoy communication while abroad by adding the O2 Travel Bolt On to your account. For £6 per day Bolt On grants you unlimited minutes, texts, and data roaming access in 63 destinations worldwide. To explore the full list of destinations covered by the O2 Travel Bolt On, follow this link .

3. Virgin Media O2’s Volt

If you have a Virgin Media broadband connection and an O2 mobile contract, you can access the Inclusive Zone at no extra cost in all Plus Plans and Volt bundles which allows you unlimited data, texts and calls in 27 international destinations as well as in Europe. 

In the event that you're not eligible for O2 Travel Inclusive Zone and haven't opted for the O2 Travel Bolt On, or you find yourself roaming in a destination not encompassed by these services, O2's standard roaming rates will apply.

Clear and confusion free roaming with Virgin Media O2

Gareth Turpin, Chief Commercial Officer at Virgin Media O2

A year and a half ago Virgin Media O2 proudly became the odd one out by not following the other major mobile networks in reintroducing EU roaming fees. All O2 and Virgin Mobile customers travelling to Europe have continued, and will continue, to roam like home regardless of whether rules and laws have changed post-Brexit.

In the current economic climate and with summer holiday season upon us, many families will be flocking to popular European destinations for a well-earned break.  Worrying about whether you can afford to use a phone while away is bonkers, and our research has shown that a quarter of Brits don’t realise they may need to pay additional mobile charges while roaming in Europe. To ease some of this pain, last year we helped save our customers an estimated £3 million per week in EU roaming charges.

Yesterday, Ofcom proposed new rules to ensure any applicable roaming charges are made clear to consumers when they head abroad. We believe that it’s important for consumers to have clear and transparent information about roaming and will continue to send alerts to our customers when they first touchdown in another country, at multiple points when they near their airtime limit and again when they reach it.

Some commentators have pointed out that we have a data ‘fair usage’ cap on roaming. We do, and we’ve never hidden this. This is the case with all operators, and it’s designed to stop abuse of roaming by a tiny minority who might be living abroad for an extended period. The key difference with Virgin Media O2 is that any of our customers with consumer contracts won’t be charged a thing up to their standard UK data limit, or the 25GB cap if their data plan is higher than that when visiting Europe – no other mobile network can say the same.

Now I realise this is an industry full of jargon, so understandably some people will worry about hitting that 25GB limit. Let me break it down. This is a hefty amount of data. It’s equivalent to 595 hours of WhatsApp voice calls, streaming more than 6,000 songs or using Google Maps while driving for 208 days straight.

I know a mobile phone is an essential item when at home or abroad, but the reality is 99% of people will never get close to that 25GB limit. And for those that do, they will receive a clear message before they get to that point outlining their options and any charges that could apply.

Beyond Europe, we have O2 Travel Inclusive Zone included at no extra cost in all Plus Plans and Volt bundles which allows millions of our customers to enjoy unlimited data, texts and calls in 27 international destinations as well as in Europe. A full list of international destinations can be found here . For those without this included in their plan, we offer an O2 Travel Bolt On for £6 a day, providing unlimited services in 63 destinations across the globe. The countries included are listed here .

For anyone about to head off on holiday who isn’t an O2 or Virgin Mobile customer, we recently teamed up with Roman (Roam On) Kemp to provide a few tips that might help you avoid some of the holiday turbulence caused by EU roaming charges. Of course, for a first-class roaming experience O2 is your best destination.

Let’s keep on roaming on.

What is O2 roaming?

Roams UK

O2 roaming is a way for customers to travel to certain destinations around Europe and be able to use their O2 SIM only or O2 pay as you go deals like they're at home and be connected to their family and friends back in the UK.

Does O2 roaming have extra charges?

One of the best benefits of having a O2 SIM only deal or a O2 pay as you go deal is that you are eligible for O2 roaming which allows you to travel to amazing destinations around Europe.

Fortunately, O2 customers will not pay any extra charges when they travel abroad to any of the O2 roaming destinations, instead of having extra costs you will be able to use only whatever you have from your allowance.

For example, if you are on a O2 SIM only deal that offers 25GB worth of data, then that is your data allowance for when you travel to any of the O2 roaming destinations.

If your O2 SIM only plan or O2 pay as you go has minutes and texts then you can use that when you are abroad and not get charged extra.

Imagine relaxing in the south of France having a coffee and posting it on your Instagram and Facebook showing off to your friends and family back home.

The best part is not being able to get charged extra for using your phone because with O2 roaming it allows you to roam like you're at home.

However, keep in mind that if you are travelling and not using your data during then turn your data off so you can save on your data.

O2 Roaming Destinations

Before you decide to go on your next holiday make sure you consider all the destinations that have O2 roaming so that you do not get charged extra for using your data, minutes and texts.

Here is a list of all the destinations that have O2 Roaming:

Europe Zone: Austria, Azores, Belgium, Bulgaria, Canary Islands, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, French Guiana, Germany Gibraltar, Greece, Guadeloupe, Guernsey, Hungary, Iceland, Ireland, Isle of Man, Italy, Jersey, Latvia, Liechtenstein, Lithuania, Luxembourg, Madeira, Malta, Martinique, Mayotte, Monaco, Netherlands, Norway, Poland, Portugal, Reunion, Romania, Saint Barthelemy, Saint Martin, San Marino, Slovakia, Slovenia, Spain, Sweden, Switzerland, and Vatican City.

So, you can travel to Barcelona or visit Greece and enjoy all the amazing beaches they have over there and still stay active and connected with O2 roaming.

Before travelling to any of the O2 roaming destinations make sure you enable your roaming data so that you are able to have data, some phones will have already have their roaming enabled but for iPhone users you must enable your roaming.

O2 roaming outside the EU

If you are planning a trip outside the EU then O2 roaming allows you to travel to international countries outside the O2 roaming destinations, however it does cost you extra and depending on where you travel to the charges can be different.

The best way to travel to anywhere outside Europe is to the O2 Rest of World Pass , there are two types of O2 Rest of World passes.

The Rest of the World 24 hour pass which is usually used for occasional trips and with this deal O2 customers can get 300 minutes, 300 texts and up to 500MB and this plan starts as soon as you get off the plane.

Now you can keep up to date with your family and friends through social media and also use Google Maps to get you around places.

The Rest of World 30 Day Pass is for O2 customers who are planning on going for a long holiday so they need a plan that can keep them active online longer.

O2 Customers will RECEIVE 2000 minutes & texts and up to 5GB worth of data which is very similar to having a O2 pay as you go deal in relation to the data, minutes and text allowance.

Both Rest of World Pass options offer this plan to 96 countries outside the EU so O2 customers can take advantage of this amazing deal.

Also keep in mind if you are using your data to stream movies, games and music it will eat up your data a lot faster so be smart with your data.

Forget O2 roaming: say hello to Holafly

Roaming with O2 is really convenient when we are travelling inside Europe , as the connection inside the EU is free of charge. However, if you are planning to travel outside of the Old Continent, you may consider other options, such as Holafly International eSIM cards .

Changing O2 roaming for an Holafly international eSIM is also very simple , you do not even have to take your O2 SIM out of your phone. Just choose the country you are visiting, select your prefered data plan and activate your eSIM, which will be sent to your email. However, you will need an eSIM compatible phone as the company does not ship its regular SIM cards to the UK.

Holafly offers a wide range of fixed price data plans especially designed for travellers, as you will be able to keep using your phone abroad at a lower price for a few weeks or a whole month , depending on your needs. This means that you know from the beggining how much you are paying for your data plan and how long it will last. This means no surprises on your phone bill once you came back to the UK.

The 2Mbps speed limit should be enough for most day-to-day use such as browsing the web, sending messages and using social media. It’s also enough for things like maps and for listening to music. If you’re streaming online video, it should be possible to stream in standard-definition. However, it won’t be possible to stream in HD quality.

The following 27 international countries are covered by the O2 Travel Inclusive Zone Bolt On:

  • El Salvador
  • New Zealand
  • United States

If you’re not eligible for the free O2 Travel Inclusive Zone Bolt On, you cannot pay for it. However, you can purchase the similar O2 Travel Bolt On, which covers 63 international destinations for £6 per day. See below for more information.

The O2 Travel Bolt On is available for £6 per day, and covers 63 international destinations.

Similar to the O2 Travel Inclusive Zone Bolt On, you get unlimited data, unlimited minutes and unlimited texts. However, there is a 2Mbps speed limit in place.

You can get the O2 Travel Bolt On by texting TRAVEL to 23336 or by enabling it via your O2 account.

The £6 daily fee will automatically be charged when you use mobile data, make a call or send a text message. Using Wi-Fi or receiving calls and texts will not trigger the charge.

The moment the charge is triggered, you'll have access for 24 hours, until the trigger resets. There are no limits on the amount of consecutive days you can trigger the Bolt On.

It is important to note you must enable the O2 Travel Bolt On before you use data, make a call or send a text. If you don't enable the Bolt On, you won't be charged the £6 daily fee - instead, you will be charged at a standard roaming rate, which can be expensive.

There is no fair usage policy on the amount of data you can use - you get unlimited data. However, there is a 2Mbps speed limit in place.

  • Netherlands Antilles
  • Saint Kitts and Nevis

What’s the difference between the O2 Travel Bolt On and O2 Travel Inclusive Zone Bolt On?

The O2 Travel Inclusive Zone Bolt On is free with selected O2 Refresh, O2 SIM only plans and Volt plans. It works in 27 international countries. You cannot buy the O2 Travel Inclusive Zone Bolt On if you are not eligible for free, however you can choose it as an O2 Extra with select tariffs.

On the other hand, the O2 Travel Bolt On is available to all pay monthly customers for £6 per day and works in 63 international destinations.

Both Bolt Ons give you unlimited data, unlimited minutes and unlimited texts. However, the O2 Travel Bolt On comes with a 2Mbps speed limit.

If you’re using your allowance for free within O2’s Europe Zone, you cannot exceed 25GB data per month if your regular allowance is greater than this amount. If you go over this limit, you will be charged £3.50 per GB until your allowance resets during the next month.

In addition, you cannot roam within the O2 Europe Zone for more than 63 days within a 4 month period - the offer is not intended for extended holidays. If O2 thinks you are abusing the free EU roaming policy, you will be given a 2 week notice, before a surcharge is applied:

The surcharge will be dropped when you return and stay in the UK for a reasonable time.

For the O2 Travel Inclusive Zone Bolt On, there is no fair usage policy on the amount of data you can use, however O2 states they may implement a temporary speed limit if your usage is deemed excessive. The O2 Travel Bolt On does not have a fair usage policy, however there is a permanent 2Mbps speed limit in place at all times.

Will I be charged if I exceed my allowance when roaming with O2?

If you exceed your data allowance or go over the 25GB limit when roaming for free in the Europe Zone, you will be charged £3.50 per GB, until your plan resets during the next month.

If you don't have an roaming Bolt On when travelling outside of Europe, or you're not in an eligible country, you will charged at a standard out of plan rate.

The out of plan rate is typically expensive, and varies between countries. For full charges, see O2 roaming rates

The following shows the O2 out of plan rates within a few international destinations.

No, 5G is only available within the UK with O2 . The maximum signal you can get when roaming with O2 is 4G.

Yes, all O2 customers can use their regular allowance for free with O2 Europe Zone, covering 48 European destinations.

Before roaming with O2 , you must enable roaming in your phone’s settings.

For Android users:

  • Go to Settings

  • Enable Data roaming

For iPhone users:

  • Go to Mobile data -> Mobile Data Options
  • Enable Data Roaming

If you're roaming in the EU and go over your data allowance or the 25GB limit, you will be charged £3.50 per GB until your plan resets at the next month.

Yes, you can tether to as many devices as you like when roaming with O2 . Any regular data limitations that apply when roaming will also apply when tethering while roaming.

The O2 Travel Bolt On is available with all pay monthly plans for £6 per day. You can get the O2 Travel Bolt On by texting TRAVEL to 23336 . Alternatively, you can purchase the Bolt On through your O2 account.

How does roaming work on O2?

Jim Martin

Before you jump on a plane or a ferry, it pays to know exactly what the score is when you use your O2 (or Virgin Mobile) SIM in a country other than the UK. Do calls, text and data come out of your allowances or will you be slapped with a hefty bill just for checking Facebook?

We’ve got all the answers you need.

Can I roam on my O2 SIM?

Yes. But whether or not you’ll be charged depends upon where you’re going, how you pay and also which tariff you’re on.

O2 Travel is what you need to use your calls, text and data abroad, and you can log into your O2 account to see whether you have it as part of your package. Alternatively, dial 202 on your phone and just ask the customer service team.

To opt into O2 Travel, sign in to My O2 and then add the O2 Travel Bolt On. It doesn’t cost anything to do this: you will only be charged if you trigger the Bolt On by making a call, sending a text or using data in a country that’s outside of the Europe Zone .

Despite having removed them in 2017, following Brexit, three of the big four UK carriers reintroduced roaming charges across the EU. However, on 10 January 2022, Virgin Media O2 ‘s Chief Commercial Officer for Mobile, Gareth Turpin, confirmed that “we [Virgin Media O2] will not be reintroducing roaming fees in Europe for customers on O2 or Virgin Mobile.”

This means O2 (and Virgin Mobile) customers are in the best position, in terms of European roaming charges are concerned, as they don’t have really worry about them.

Note: Don’t forget to enable data roaming in your phone’s settings, otherwise, your apps and browsers will tell you there’s no internet connection.

Roaming in Europe

If you’re heading to Europe, great news. You don’t need to worry as your phone will work just like it does in the UK. Any calls or texts you make will come out of your normal allowance, and the same goes for data from your bundle.

Just check O2’s Europe Zone to make sure your destination country is included.

If you’re on a pay-as-you-go bundle, check out the included countries here (the list is different to the Pay Monthly list). Note that Guernsey, Isle of Man, Jersey, Monaco and Switzerland are excluded for PAYG customers. You can get 100MB of data for these destinations for £1.99 per day.

Also, note that using mobile data on a cruise ship isn’t covered, but you should be able to use the ship’s own Wi-Fi. Making and receiving calls on a ship costs £2 a minute, and sending each text costs 50p.

Roaming outside Europe

If you have a tariff that gives you free O2 Travel in the Inclusive Zone, the following countries are included and you won’t be charged for calls, texts or data as long as you don’t go over your usual allowance:

  • El Salvador
  • New Zealand
  • United States

If you don’t have free O2 Travel on your tariff, then you’ll need to opt into O2 Travel (you can also do this by texting O2TRAVEL to 23336) before you head abroad.

You’ll be charged £4.99 per day, but only on the days that you ‘trigger’ the Bolt On. That means the first call you make, text you send or data you use will start O2 Travel for that day, which runs from midnight to midnight based on the capital city of the country you’re in.

How does roaming work on O2?

What does O2 Travel include?

For your £4.99 per day, which you’ll be billed if you’re not eligible for the ‘Inclusive Zone’ or Europe, you get 120 minutes, 120 text and unlimited data.

O2 says there’s no cap on data at all, but that “speeds may vary” which, reading between the lines, means you’ll see a slow-down in your connection speed if you’re using more than the amount in O2’s fair use policy.

Is O2 good value for roaming?

Considering EE, Three and Vodafone have all reintroduced roaming charges – even within Europe – since Brexit went into effect, Virgin Media O2’s decision to abstain from reintroducing them is a huge win for customers; especially those who like to travel and are likely to find themselves hopping around Europe.

If you’re off to a destination where you can’t use your allowances, you might be able to get a better deal than the £4.99 per day charge for O2 Travel.

Pop into a phone shop – or pre-book online – and pick up a local pre-pay SIM when you arrive at your destination. This is often a way to use your phone – especially mobile data – for a much-reduced cost. Some operators even sell ‘tourist SIMs’ for exactly this reason. Do your research before you go and you could save a lot.

There are disadvantages of doing this, including the fact that people won’t be able to call you on your normal number while you’re using a different SIM. Of course, if you have a dual-SIM phone, then that’s not an issue, but do watch out if you intend to keep your O2 SIM in a phone, so people can contact you, as you might be charged for receiving calls and texts if you’re outside of the inclusive zones.

Where is the O2 Travel Inclusive Zone? Phone provider’s data policy explained

Young man at beach bar looking at phone

We’ve all been there – the plane lands, you whip out your phone and then feel a moment of panic over whether to turn on data roaming.

Let alone agonising over how much it will cost to call home.

Depending on your contract, and your network, using your phone on holiday can be just the same as at home – or very pricey.

It’s all got so much more complicated since Brexit , as some companies reintroduced roaming charges .

The trick is to get clued up and sorted before you go, so there are no unexpected surprises.

Because when you’re hitting the beach for some much-needed R&R , fretting about your phone bill will just pile on the stress.

So if you’re on the O2 network, what’s included – and what isn’t?

Here’s what you need to know.

Is O2 free in Europe?

Woman using smartphone against Eiffel Tower in Paris on a sunny day

In its Europe Zone, O2 contracts work as they do in the UK – so you’ll get the same number of minutes, texts and the same data allowance (up to a limit of 25GB). You can use this for up to 63 days in any four-month period – more than this will trigger a ‘fair usage’ text and after that you could be charged £3.50 per GB for data, 3.3p per minute for calls and 1p per text.

If your data allowance is more than 25GB in the UK, it will be capped at that level in Europe – you can use more, but you’ll have to pay for it.

The Europe Zone also applies to pay-as-you-go – data will come out of your allowance or be charged as it would in the UK.

Note that a handful of Europe Zone destinations on pay-as-you-go are slightly different: in Guernsey, Isle of Man, Jersey, Monaco or Switzerland, you can buy a travel bolt-on £1.99 for 100MB of data, texts are 1p and calls within these countries or back to the UK for 4p a minute.

Countries in the O2 Europe roaming zone are:

  • Canary Islands
  • Cyprus* (excluding Northern Cyprus)
  • Czech Republic
  • French Guiana
  • Isle of Man
  • Liechtenstein
  • Netherlands
  • Saint Barthelemy
  • Saint Martin
  • Switzerland
  • United Kingdom
  • Vatican City  

What’s the O2 Travel Inclusive Zone?

The ‘Travel Inclusive Zone’ is a list of 27 countries outside of the Europe Zone.

Tamarindo Beach and Estuary, Guanacaste, Costa Rica

Countries in the O2 Travel Inclusive Zone are:

  • El Salvador
  • New Zealand
  • United States

Who can get the Travel Inclusive zone?

It’s offered as a bolt-on on certain O2 Selected Plus Plans (including pay monthly and 12 and 24-month sim-only) to cover unlimited minutes, texts and data roaming in these areas (with no cap on the data).

It’s not available on 30-day sim-only tariffs or on pay-as-you-go.

What about outside the Travel Inclusive zone?

To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video

If you’re travelling outside of the Europe Zone and do not have the O2 Travel Inclusive Zone Bolt On, then if you’re on pay monthly you can buy the the O2 Travel Bolt On for £6 a day which gives unlimited minutes, texts and data in selected destinations.

O2 has a dedicated page where you can check to see if the country you’re visiting is covered. You can add the bolt-on by texting TRAVELON to 21300.

For pay as you go, it’s not offered, so you’ll be charged international roaming rates outside of the Europe Zone.

You can check international roaming rates on O2’s dedicated page – in the US, for example, data is a whopping £7.20 per MB on pay-as-you-go, and calls cost £2 a minute to make and receive.

Vodafone / Three deal could leave consumers and businesses worse off

The deal, which seeks to combine 2 of the 4 UK mobile network operators, could lead to higher prices for customers and affect investment in UK mobile networks.

o2 business travel abroad

Vodafone UK (which is owned by Vodafone Group Plc) and Three UK (which is owned by CK Hutchison Holdings Limited) are two major providers of mobile telecommunication services in the UK. Last year both businesses announced a new joint venture agreement which would bring their 27 million customers under a new, single network provider.

The Competition and Markets Authority (CMA) launched its initial Phase 1 investigation in January after it was notified by Vodafone UK and Three UK. This 40 working day review is designed to identify whether the deal may lead to a ‘substantial lessening of competition’ – focusing on the potential impact on consumers and businesses in the UK – and therefore requires an in-depth, phase 2 investigation. Phase 2 investigations allow an independent panel of experts to probe in more depth initial concerns identified at Phase 1.

The CMA is concerned the deal, which combines 2 of the 4 mobile network operators in the UK, could lead to mobile customers facing higher prices and reduced quality.

The CMA’s Phase 1 investigation found that Vodafone UK and Three UK provide important alternatives for mobile customers. Both have made significant investments in their networks in recent years – which includes the rollout of 5G. Three UK is also generally the cheapest of the four mobile network operators. The CMA is concerned that combining these two businesses will reduce rivalry between mobile operators to win new customers. Competitive pressure can help to keep prices low, as well as provide an important incentive for network operators to improve their services, including by investing in network quality.

The CMA is also concerned that the deal may make it difficult for smaller mobile ‘virtual’ network operators such as Sky Mobile, Lebara and Lyca Mobile to negotiate good deals for their own customers, by reducing the number of mobile network operators capable of hosting these ‘virtual networks’.

When announcing their deal last year, both Vodafone UK and Three UK claimed that combining both businesses would result in significant benefits to customers as well as speed up the deployment of new technologies. These types of claims can sometimes justify clearing a deal that would otherwise raise competition concerns.

Vodafone UK and Three UK’s claims are based on a number of assumptions about how they will combine and invest in their networks post-merger. The CMA considers these assumptions need more detailed assessment, particularly given the CMA’s concerns that the merger may reduce mobile operators’ overall incentives to invest in their networks.

Julie Bon, Phase 1 decisionmaker for this case at the CMA, said:

Millions of people in the UK depend on effective competition in the mobile market in order to access the best deals for them. Whilst Vodafone and Three have made a number of claims about how their deal is good for competition and investment, the CMA has not seen sufficient evidence to date to back these claims. Our initial assessment of this deal has identified concerns which could lead to higher prices for customers and lower investment in UK mobile networks. These warrant an in-depth investigation unless Vodafone and Three can come forward with solutions.

Both Vodafone UK and Three UK have five working days to respond with meaningful solutions to the CMA, otherwise the deal will be referred to a more in-depth Phase 2 investigation.

More information can be found on the  Vodafone / CK Hutchison JV case page .

Notes to editors

Vodafone UK is owned by Vodafone Group Plc. Three UK is owned by CK Hutchison Holdings Limited.

The 4 mobile network operators in the UK are Vodafone UK, Three UK, BT/EE and Virgin Media O2.

‘Virtual’ network operators do not own their own networks and rely on access to a mobile network operator’s network to supply mobile services to their customers.

The CMA’s remit, by law, is to assess the potential impact of a merger on competition. It cannot consider other potential effects that a merger might have, for example, on access to personal data. National security concerns are a  matter for the UK government , which may choose to intervene under the National Security and Investment Act if it finds concerns.

Phase 2 investigations last 24 weeks (extendable by up to 8 weeks in certain circumstances) and are led by an independent panel of experts.

As part of its normal merger review process in a regulated sector, the CMA has engaged with Ofcom, the sectoral regulator which oversees mobile communications.
