This morning, I did software update. I tried calling someone and I got a notification “Your phone is not registered on a network, so you can only make emergency calls.”. I tried calling T-Mobile customer support, but this gave me the same notification. If relevant, my phone is android, I have not changed any settings and I have not downloaded any new apps for a relatively long time. (The last call I had was on March 13, and everything was fine then.)
Is anyone else having the same issue?
Has anyone done the most recent software update, and is able to make calls now?
Does anyone know what are the solutions to this issue?
