Response
+CPMS:
> Parameter Memory from which messages are read and deleted Write command AT+CPMS= Parameter See Test command +CPMS: OK/ERROR/+CMS ERROR 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。
