Hi @1019, sorry to hear about this. 
Your question has been translated to English as this is an International forum.
Have you tried to manually register on your operators network? You can do so if you start a search for networks in your area in Settings > More > Mobile networks > Network operators. Wait for the search to finish and see if you can connect to your operators 2G/3G or 4G network.
Keep me posted!
Same problem for me . I have tried everything but the phone stopped detecting networks. Sometimes it stars working for a few hours but it stops working again for days or even a week. I don´t know what to try. It happens with different SIM card and different providers. Any help?
