Im new at AT commands, and I'm having an issue when I try to recieve a sms in my SIM card. It's a D-link DWM-157 (I guess that's it) How I'm doing:
AT OK AT+CMGF=1 OK AT+CPMS? +CPMS: "SM", 0, 0, "SM", 0, 0, "SM", 0, 0
---> and then it returns the SM as 0,0, as if the SIM card had no max sms storage capacity.
I tried plugging off and on again the modem and sometimes it works just fine, but when I reset it again, the problem comes back.
I'm brazilian, so I'm sorry if you don't understand something.
Can you guys help me?
Thank you very much!
