As well as the allocated data, each O2 Travel plan allows unlimited calls to UK mobile numbers and landlines. The plan offers 50GB of data and 500 minutes of inclusive international minutes from anywhere in the EU or UK to anywhere in the EU or UK.
You are not allowed to use the product for any of the following.
- Calls to Premium numbers
- Calls to UK 08 non-geographic numbers
- Usage outside the UK or EU
- International calls outside the inclusive minutes
Any use of the above will use up your allowance and your eSIM service will stop working.
