I recently moved from India to UK and I am unable to use Apple wallet

Welcome to Apple Support Community!

United Kingdom is a supported country or region for Apple Pay

Countries and Regions that support Apple Pay : https://support.apple.com/en-us/HT207957

India is not on that list, so leads me to believe your region on your device is not set correctly.

You can change your device country or region by going to: https://support.apple.com/en-us/HT204031

Settings > General > Language and Region > Change to United Kingdom

Also may want to change your Apple ID Country/ Region. You can do that by following the resource below.

Change Apple ID country / region : https://support.apple.com/en-us/HT201389

Hope this helps ;)

Hi RichaMehta,

Welcome to the Apple Community.

Wondering if you have changed your country in your Apple ID account yet ?

Your Apple ID is the account you use to access everything Apple,

including services like the App Store, Apple Music, iCloud, iMessage, FaceTime, and more.

It includes the email address and password you use to sign in,

as well as the contact, payment, and security details you use across Apple services.

If needed, try following this article from Apple Support

How to change your AppleID Country or Region:

       NB: Before you update your location, you must spend your store credit, (or ask for your balance to be set to zero.)

       cancel your subscriptions, and get a payment method for your new country or region

For more details see the complete article: https://support.apple.com/en-us/HT201389
