If someone sends me a text message it can be over a day before I receive it on my iPhone or iPad.
Messages have been sent from various networks and all seem to take hours or days to arrive.
Very frustrating especially when you’re trying to log into a system that text you a verification number.
This has just started over the last week or so, no software updates have been made on the phone and I’ve tried rebooting it which didn’t sort out the problem. No changes have been made to the phone settings.
