Hello!
If you want to update your telephone number please try one of the following steps. Choose the device that you are wanting to update it on.
- iPhone: go to Settings > Wallet & Apple Pay > scroll down to Transaction Defaults and update your delivery address, email address and phone number.
- Apple Watch: in the Apple Watch app on your iPhone, tap Wallet & Apple Pay > scroll down to Transaction Defaults and update your delivery address, email address and phone number.
- iPad: go to Settings > Wallet & Apple Pay > scroll down to Transaction Defaults and update your delivery address, email address and phone number.
- Mac with Touch ID: in System Preferences, go to Wallet & Apple Pay > Click Contact and Shipping, and update your delivery address, email address and phone number.
If that does not resolve your issue, you can remove your card all together from Apple Pay. Then restart your device and then add your card back again to Apple Pay.
Cheers!
