O2 roaming by destination

Pick your destination

How to avoid O2 roaming charges

  1. Before you fly, install a travel eSIM at home on Wi-Fi.
  2. On landing, set mobile data to the eSIM and turn on data roaming for the eSIM only.
  3. Turn data roaming off for your O2 SIM so background data doesn’t start a charge. You can still receive calls and texts.

Questions UK travellers ask

How much does O2 charge for roaming?

O2 Travel Bolt On: £7 a day, charged only on days you use your phone abroad, with unlimited calls, texts and data at up to 2 Mbps in 74 destinations outside Europe. O2’s Europe Zone is priced separately, by plan.

Is a travel eSIM cheaper than O2 roaming?

It depends on where you go and for how long. The table above shows a week in each destination, using O2’s lowest published option and a Graba SIM plan of about 0.7 GB a day. O2’s price also includes calls and texts.

Can I keep my O2 number while using an eSIM?

Yes. Keep your O2 SIM in your phone for calls and texts, turn data roaming off for it, and use the eSIM for data.
