What happens if I go over my allowance when roaming with BT?

If you go over your allowance, you may be charged for additional usage. The amount you are charged depends on the country you are in.

If you’re within an EU destination covered by BT Roam Like Home, you will be charged at between 9.47p and 11.42p per MB over your regular allowance.

Alternatively, you can avoid the out of plan rates by purchasing a data add-on.

A data add-on lasts for one month and will be applied to your regular plan, meaning you can use it within the UK and in Roam Like Home European countries.

BT Mobile data add-on Cost
500MB £5.21
1GB £7.83
5GB £15.67
10GB £20.90
15GB £31.35

For any country outside the EU or not covered by Roam Like Home, you will not be able to use your plan’s allowance. Instead, you will be charged at the BT out of plan rate.

Alternatively, you can purchase a BT Mobile Travel Data Pass add-on for data in selected countries.
