Notes 1) The Mobil Equipment storage "ME" has capacity for 25 short messages
2) The storage "MT" is a combination of "ME" and "SM" storage. If "MT" is
chosen indices < 26 refer to ME" storage while indices 26 or higher are
associated with the "SM" storage
3) Incoming short messages with message class 2 (see GSM 03.38) will be
stored in the "SM" storage only. Therefore, the AT^SMGO:2 indication (see
AT^SMGO command) can occur without a preceding AT^SMGO:1 indication.
一些概念：
MEM1：读取和删除短信所在的内存空间。
MEM2：写入短信和发送短信所在的内存空间。
MEM3：接收到的短信的储存位置。
具体用法：
1、语句：
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。
