Make the next step if you want to check the coverage you have the phone and to see a scientific manner, using data, how much signal gets our device.
The answers after the jump.
Dialing * 3001 # 12345 # * and press the call button will see this weird menu, but the point is displayed next to our phone company. Coverage is shown in decibels and in concrete terms.
The closer we are to -150, the worse the coverage and if we get to -50 will we have a good sign.
The coverage that we have not that is bad, is half shooting well.
