iMessage stuck 'waiting for activation' following iOS 13.0 update
Since updating my iPhone to iOS 13.0, iMessage doesn't work. It says 'Waiting for activation'. FaceTime's doing the same thing.
I've tried switching iMessage and FaceTime off and then on again, Airplane Mode on/off, logging out of iCloud and logging back in, switching the phone off and then on, removing and replacing the SIM card, and doing all of those things together. And I've updated my APN settings. I've also tried waiting, as Apple says it can take up to 24 hours to activate (though I doubt it does take that long).
Any suggestions? Thanks in advance.
