iMessage won't turn back on overseas
In Europe for vacation. We're from US. My son turned off iMessage for some reason, then was unable to reactivate it. We have a Global Data Talk and Text Plan for the trip through Verizon. Since turning off iMessage he can't get it to activate with his phone number but it does work via his e-mail.
Is this a foreign phone carrier issue? Is it likely he will need to wait until he's back in the U.S. to use his phone number for iMessage?
