Home screen, menu, settings, about phone, battery use, then hit CELL STANDBY, will show you time without a signal.. mine right now is at 60%!!!!
Then to see if you are connected do the following:
home screen, menu, settings, about phone, status,scroll down to MOBILE NETWORK STATE.. it will show if it is connected or not...
When you notice there is no EV or 1X, check your connection.. it will show mobile network state as either connecting or not connected. FRUSTRATING
