Using the +CMGL AT Command to List SMS Messages of a Certain Status from a Message Storage Area. The AT command +CMGL (command name in text: List Messages) is used to list messages of a certain status (for example, "received unread" and "received read") from a message storage area.
The AT command +CMGF (command name in text: Message Format) is used to select the operating mode of the GSM/GPRS modem or mobile phone. It takes one parameter. The value of the parameter can either be 0 or 1.
Most common reason for returning OK would be that there are no messages stored in memory.
To check if that's the case run the reading command without setting the Preferred Storage.
