I am getting a good signal strength value[15-20] for AT+CSQ command, but the atd<phone number> is not making the calls. When I checked the SIM registration value using AT+CREG? command, I got "2,2", which tells the SIM card is not registered with network. Then how the signal strength is coming as such a good value range[15-20] ?
