As well as the allocated data, each O2 plan allows unlimited calls to UK mobile numbers and landlines and unlimited SMS’s to UK mobile numbers.
The following are not permitted:
- International calls and SMS’s
- Calls to Premium numbers
- Calls to UK 08 non-geographic numbers
- SMS’s to Premium or short numbers.
Note that coverage is strictly limited to UK and EU countries and the service will not work anywhere else.
If you use the O2 eSIM plan for any of the above purposes your plan may become locked for a period. So please ensure that you do not make any out of bundle calls, send any out of bundle SMSs or use the eSIM plan outside the UK and EU.
