Ok so 8 months ago I got Nokia Lumia 630. So for the first few months the phone was working perfectly but after the update of the system my phone started to glitch out. Then the NO NETWORK FOUND problem started. I restarted my phone and it worked and after few hours it showed the same error. I had 3 bars of frequency but when I want to go into my cellular and SIM setting it says no network found. I can't recieve messages, I can't send messages, when i call someone it doesn't ring it's just stuck on the call screen. And of course I can't use my mobile network... Can someone help me btw I sent it to service twice and they said the phone is working properly. I changed my SIM and it still gets the same error. Can someone please help me?
