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:

  • Azores

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.
