My phone (which was bought only 2 days ago) has suddenly lost connection with mobile network. "Emergency calls only" is written on lock screen, near signal power bar there is a small red 'x'. I tried turning it off and on, tacking sim card out and putting it back in, trying to connect to mobile network manually through the settings "Service providers" (it says "Could not connect to network now. Please try again later." when I try to connect manually), changing network mode (to all possible modes). Still no luck. I can't send an sms or make a call.
What should I do?
