Roam freely in the EU

EU Roaming is when you use your phone while travelling abroad to countries that are within the European Union.

Unlike some other networks, with O2 you can roam in the EU freely and easily. Use your devices for calls, texts, and data as you would at home (free up to 25GB) while adhering to fair usage policies and provider-specific terms.

We even won Best Mobile Network for Roaming at the Uswitch Telecoms Awards in 2022, 2023, 2024 and 2025.

At O2, whenever you purchase a Pay Monthly SIM, you'll automatically get free EU Roaming up to 25GB. So whether you're soaking up the sun, or hopping from city to city, we'll keep you connected.

Yes, you do. Our Pay As You Go SIMs include EU Roaming. This means you can use your calls, texts, and minutes as you would at home.

However, this depends on which country you're travelling to. So make sure to double-check before you leave.

Yes. While roaming in the EU, there’s a limit of 25GB.

If your UK monthly data allowance is more than 25GB, it’ll be limited to 25GB when in our Europe Zone.

If your UK monthly data allowance is less than 25GB, you can use up to your UK allowance while in the EU, just like at home.

If you use up your monthly allowance or hit the 25GB limit, you’ll need to sign in to My O2 and add a Data Bolt On to avoid extra charges.

Jet-setting outside of the EU? The good news is, we've got you covered.

With our O2 Travel Inclusive Zone Bolt On, enjoy inclusive data roaming in 27 international destinations. Even if your travels extend beyond our Inclusive Zone, you can opt for our full O2 Travel Bolt On for just £7 per day in certain selected destinations.

No. Free EU Roaming is only available with SIMs for your phone currently. If you have a pay monthly SIM with O2 ​for your tablet, it will only work in the UK.

Yes, if you’re staying abroad for an extended period of time, restrictions may apply under our fair usage policy.

If you exceed your roaming allowance, you may need to buy a Bolt On or pay standard roaming rates, depending on your destination and plan. We'll send you a text you before you reach your limit.

Yes, it does. When you're with O2, you can still make calls, send text messages, and use your mobile data (up to 25GB) as you would at home whilst roaming abroad in the EU.
