how to change your phone number on apple pay

You can change the phone number associated with Apple Pay here:

Settings → Wallet & Apple Pay → Phone → choose between Add Phone Number or Add from Existing Contact.

You can also add your new number under your own contact in the Contact app. After that, the number will also appear in the Apple Pay menu and you can select it.

Once the number has been added, select it from the list - so that a "check mark" appears next to the phone number.
