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.

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.

BT Mobile Travel Data Pass add-on

By purchasing a BT Mobile Travel Data Pass, you will get a set amount of data to use in 12 selected countries outside the UK and the EU.

For £6, you will get 500MB data for 24 hours.

Any unused data after 24 hours will be lost. You must repurchase the add-on after 24 hours if you wish to continue using the Travel Data Pass.

You can purchase a Travel Data Pass from your BT account.

To track your Travel Data Pass usage, you can login to your BT account or download the My BT app.

The BT Mobile Travel Data Pass add-on works within the following 12 countries:

1. Andorra
2. Australia
3. Canada
4. China
5. India
6. Mexico
7. New Zealand
8. South Africa
9. Thailand
10. Turkey
11. United Arab Emirates

Does BT have a fair usage policy when roaming?

Yes, regardless of the plan you have, the maximum amount of data you can use when roaming in a given month is 50GB, as defined in the fair usage policy.

This fair usage policy even applies to plans that have a data allowance greater than 50GB.

BT Mobile zones

Countries outside the UK are grouped via zones.

If you go over your allowance in an European Roam Like Home country, or you use BT Mobile in another international country not covered by Roam Like Home, you will be charged at an out of plan rate.

It is important to plan ahead and track your data usage, as the out of plan rates can be very expensive.
