Even when i have five to four bars, my phone won't maintain cellular connection.
I could be using it and then suddenly..... No coverage and i am the only one in the room with that problem.
When this happens i have to either restart the phone or switch the data connection off and on again.

It happens so many times, i don't know what to do anymore, tried factory resets, changing providers, switching to 3/2 G ,nothing works.

I need help.
