EU roaming up to 25GB, at no extra cost
Your data (subject to roaming limit), minutes and text allowances will work in our Europe
Zone just like they do at home. That’s because we’re the only major network to include roaming in our Europe Zone as part of our tariffs (up to 25GB).
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 reach the limit, you'll need to buy a Bolt On. If your UK data allowance is less than 25GB this amount will apply in the EU too.

EU Roaming is when you use your phone while travelling 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 Network for Roaming at the Uswitch Telecoms Awards in 2022, 2023, 2024 and 2025.

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.
