iMessage Issue
I changed the SIM card on my iPhone Xs Max but the iMessage number remained with the old SIM card number and not the new one.
Under My Number in Settings - Phone, my new number appears but the old number remains in iMessage and is not able to activate iMessage.
How can I change my iMessage number so that it activates iMessage with my new number?
Greatly appreciate the help.
iPhone XS Max, iOS 13
