Why does my iPhone randomly switch to send SMS messages rather than iMessage, even when I have data? It’s started happening ever since I switched networks to EE in December.
When I go to Settings, I see iMessage has turned itself off, and then the phone number to “register” is the original one associated with the SIM card, rather than my actual number from the PAC code. I didn’t even put the SIM card in the phone until I got the confirmation of the switch over.
Then I’ll check again a few hours later and it’s back to normal. WEIRD.
