1- Let's assume you want to write a new SMS to the storage and the destination address is the
number [phone]. We suppose you already have set up the device for text SMS mode as
described on the previous paragraphs:
command:
AT+CMGW="[phone]"
response:
>
now you can insert the message text in IRA format (note that the IRA format and ASCII format
coincide for the alphabet characters but not for the other).
…. here will be inserted the SMS message text….
conclude text with the character CTRL-Z
response:
+CMGW: 3
OK
In this case, the new SMS was successfully written to the location index 3 of the selected write
memory (always "SM" SIM Card memory).
3.5.4 Sending an SMS previously stored
An already written SMS can be sent from the selected storage <memw> (in the current SW version
only "SM" is supported).
To send the written SMS its location index is needed:
• send command AT+CMSS=<index><cr>
where:
<index>: SMS location index
• wait for response:
Response Reason Action
+CMSS: <mr>
OK
Message has been successfully
sent. <mr> represents the
message reference number.
