I've been getting an error 2 message on and off all day today with text messages. Then phone also doesn't accept or make calls either.
Hi there @Careneig , one other thing to take note of is how good your signal is and if your device has a good charge. I noticed the other day that I was having that problem intermittently and realized my device was in power saving mode. 🤞here's hoping that a restart as @KAPABLE-K suggested or charging up rectifies the problem.
Can you try restarting the phone, if that does not work try taking the SIM out then put it back in also clear the message app cache.
