• Making calls and sending texts within our Europe Zone (excluding the UK) to any other country in our Europe Zone – including the UK.
• Receiving calls and textx within our Europe Zone
• Using your monthly data allowance in our Europe Zone (subject to our Roaming Limit)

• Making calls or sending texts from the UK, to countries outside of the UK.

If you go over your total monthly data allowance in our Europe Zone, you'll need to add a Bolt On to keep using data. The options and cost are the same as if you were in the UK. You can do this by signing into your My O2 app.

If you add a Bolt On and don’t use all the data before heading back to the UK, you’ll still be able to use it when you get home. And if you add a Bolt On in the UK, you’ll also be able to use it in our Europe Zone.

If you use your phone outside of our Europe Zone, our normal roaming charges will apply.

It's a good idea to double check if you'll be travelling within our Europe Zone before you go away. Some European territories are not currently part of this zone and can incur roaming charges unless you add our O2 Travel Bolt On.

Albania, Greenland, Monaco, Montenegro and Switzerland are not part of our Europe Zone, for example. Nor are Guernsey, the Isle of Man, or Jersey.

You can only use our services for periodic travel (like holidays or short breaks) in our Europe Zone (excluding the UK). Otherwise we may charge you or have to suspend you from using our services in our Europe Zone (excluding the UK). If this has happened to you and you think it might be a mistake,call 202 from your mobile or 0344 809 0202 from any other phone.

Use of our services in our Europe Zone is subject to our fair usage policy.

Tariffs with more than 25GB of monthly data

If your UK monthly data allowance is over 25GB, you’ll have a Roaming Limit of 25GB when roaming in our Europe Zone. This means you can use up to 25GB of your allowance at no extra cost – we’ll text you if you’re getting close to the limit, and again if you reach it.

If you’re on the new system and have an unlimited data allowance, your data service will stop when you reach 25GB. You’ll need to buy a data roaming Bolt-On to continue using data.

For all other customers, whether you’re on the old system or the new system, you can still use data if you reach our Roaming Limit but you’ll be charged £3.50/GB for your ongoing usage.

These charges will apply until the following (depending on which is earliest);

• You use up your monthly UK data allowance**
• You return to the UK
• You reach your next bill cycle

**If you use all your UK data allowance when roaming outside the UK, you’ll need to buy a data Bolt On if you want to keep using data. See our data Bolt Ons here.

Tariffs with 25GB or less of monthly data

These tariffs are not subject to our Roaming Limit of 25GB. But if you use all your UK data allowance when roaming outside in the UK, you’ll need to buy a data Bolt On if you want to keep using data. See our data Bolt Ons here. 

You can also roam as an O2 Pay As You Go customer in Europe at no extra cost.
