AT+CPMS=?

作用：

測試命令。用於得到手機所支持的儲存位置的列表。在我的SIEMENS M55手機上返回：

AT+CPMS=?

+CPMS: ("MT","SM","ME"),("MT","SM","ME"),("MT","SM","ME")

表示手機支持MT(手機終端),SM(SIM卡),ME(手機設備)

2、語句：

AT+CPMS=”MT”,”ME”,”SIM”

設置MEM1爲MT，MEM2爲ME，MEM3爲SIM

3、語句：

AT+CPMS?

作用：

得到當前的設置。

例如通過第二條語句的設置以後返回：

AT+CPMS?

+CPMS: "MT",7,150,"ME",7,100,"SM",0,50

表示MT裏面有7條短信，總共可以儲存150條。ME裏面有7條，共可以儲存150條。SIM卡上可以儲存50條
