Phone number not verifying for imessage
I am traveling abroad without cellular service and my iMessage seems to have decoupled from my phone number. I am receiving messages to my iCloud email but not my phone number. When I try the steps listed on the help pages I’ve found, it always is stuck at verifying number and a spinning wheel is present for both IMessage and FaceTime for my number. Is there a way to fix this? I’ve never had this problem when traveling in airplane mode before.
