AT+CPMS=?

作用：

测试命令。用于得到手机所支持的储存位置的列表。在我的SIEMENS M55手机上返回：

AT+CPMS=?

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

表示手机支持MT(手机终端),SM(SIM卡),ME(手机设备)

2、语句：

AT+CPMS=”MT”,”ME”,”SIM”

设置MEM1为MT，MEM2为ME，MEM3为SIM

3、语句：

AT+CPMS?

作用：

得到当前的设置。

例如通过第二条语句的设置以后返回：

AT+CPMS?

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

表示MT里面有7条短信，总共可以储存150条。ME里面有7条，共可以储存150条。SIM卡上可以储存50条
