iMessage worked while I was syncing iCloud from my old iPhone to my new, and iMessage was working fine until I erased my old iPhone (ready for trade in). Now, iMessage & Facetime wont activate; I’ve tried literally everything Apple (or any forum) suggests; turning iMessage on/off, signing out/in of iCloud, activating Airplane mode, restarting the phone, resetting network settings, removing & re-inserting the sim… literally everything.
I still receive/can make SMS and calls. When looking in my iCloud account, it says my SIM is not associated with an Apple device?
I don’t know any way to contact an agent for help… so here I am.
