Notes 1) The Mobil Equipment storage “ME” has capacity for 25 short messages

  1. 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

  1. 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:

. 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)

. 语句: AT+CPMS=”MT”,”ME”,”SIM” 设置MEM1为MT,MEM2为ME,MEM3为SIM

. 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。
