How much does it cost to call a UK mobile number that is abroad?

The good news is that if you’re calling a UK mobile number from your phone with a UK SIM, the call will be classified as a domestic call on your end. That means you’ll pay the same rate you’d pay if the phone was in the UK. The call will come out of your monthly minute allowance just like any other domestic call or, if you have a plan with unlimited UK calls, it will be free.

However, the person picking up the call will likely face roaming charges for using their UK device overseas, regardless of where the call originated from. Roaming charges vary depending on which network provider you're with, and which country you're in. For more information, check out our guide on data roaming charges.
