IMessage not activating and can't select number to receive I got a new SIM card and now I message is not working. Firstly I could only select my e-mail address as the means of being reached and my number is not in bold and can't be ticked. Also when I turn I message activation off and back on again it comes up with an error and just says waiting for activation. Any ideas?
Apple servers need time to verify your information and to Activate iMessage uses, that can be as fast as 1 hour, or up to 24 hours in rare cases.

Some patience is required since it is your privacy apple is working on to protect.
