You'll see a print-out of the battery voltage in mV, so in this case its 3.726V

You can ask the FONA for the signal strength with the command '''i'''. The reply is a number, but you can convert it to dBm. Try to have the signal strength higher than 5 in order to make calls, SMSs, etc. In this case, I've got a 10
