Message Overwriting +Wmgo - Multitech MMCModem GPRS (MTMMC-G) Reference Manual

Message Overwriting +WMGO

Description:
The +CMGW command specifies a location in the SMS or Flash memory for the next SMS to be stored
when the +CMGW indicates a message is ready to be stored. The defined location is used only once:
+WMGO has to used again to perform another overwrite.
Important Notes:
•
If the external application specifies a free location and an incoming message is received before the
AT+CMGW command occurs, the product may store the incoming message at the specified available
location. If the user then issues an AT+CMGW command without changing the location with another
AT+WMGO, the received message will be overwritten.
•
The location number is not kept over a software reset.
