No connection with mobile network

[passick]

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?

Get a brand new SIM card

That sim works in another phone.

It doesn't matter,just get a brand new micro SIM crad

[passick]

Why do you still think that sim is the problem? I got this sim card together with the phone. That means that it is just 2 days old. It was working fine.

[Uliwooly]

Was it a regular SIM card and you trimmed it or is it a micro SIM card

[passick]

It's a nano sim card that I got at operator's store. They gave it to me as a replacement to my micro sim card, because z3 compact supports only nano sim cards.

That's correct, I would double check with your carrier/network

I have the exact same problem. I'm thinking it happened because I washed my phone and water got in it. 5 minutes ago I put my friend's sim card in it and it actually showed service bars but I couldn't make a phone call, and it went off again saying "no service". Please inform me if you find any solution.

I got similar issue but the only thing is phones randomly disconnects itself from the mobile network in some days. Then no matter you manually search for the network and try registering, it simply wont connect to any network.

Your only solution is to reset the phone or turn off and on and it again auto catches your operator.
