Is there software or an application available whereby I can monitor the signal strength of all available mobile phone networks at the same time?
I can monitor signal strength via my android device but currently I have to change SIM card every time I want to monitor the next network. To do this on every network in 3 or 4 nearby locations is too time consuming as it would mean I must change SIM card 20+ times.
Ideally I want to record each network rssi level for a designated location.
