Changed SIM and cannot get new number under imessage
Can some help me get my new number to show up for imessge and face time? I have turned both off and reset the network and phone, did not work. When I log in to my apple id it shows my emails, with checks and my old number with a loading symbol and it keeps saying waiting for activation. I just moved from the US to Germany. Under phone it shows my new number, under the carrier setting it shows my number I can make a receive calls. It is only the imessage and face time that will not load.
