Hi
I have some device with cellular modems.
Modems can be CDMA or GSM.
How can I determine in runtime cellular standard (CDMA or GSM) of each modem?
Is there any AT commands for this?
Thx
Best regards
Presumably, only a GSM modem will accept GSM-specific commands, and vice-versa… 
Simply type: AT+CSCS?
and scan the modem’s reply for “CDMA”, (6 characters)
that works for me
