FaceTime and iMessage not working
It doesn’t let me FaceTime anyone it always says “(number) in the contact card is not available” and I can’t send iMessage anymore, all messages are always texts since I’ve been away. I went on holiday for a month and bought a temporary SIM card when I was away and since I’ve put my normal SIM card back in both FaceTime and iMessage haven’t work, not sure if they relate to each other but how can I get it to work again?
