Can you use Apple Card in Great Britain

If you already have one, you can use it in the U.K. to pay for things wherever Apple Pay is supported or if you've a physical Titanium Card, you can use it anywhere MasterCard is accepted.

You cannot however, at this time, apply for an Apple Card in the U.K. It is currently a U.S. only option as you require U.S. citizenship or legal residency, and a verified U.S. mailing address that is not a P.O. box.
