+WMGO – Message overwriting
Description:
The +WMGO command is used to specify a location in the SIM or Flash memory, for
the next SMS storing with +CMGW command. The defined location is used only once:
+WMGO has to be used again to perform another overwrite.
NOTE:
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 mes-
sage 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.
If the storage area is changed with the AT+CPMS command, the value of WMGO will be
reset to 0.
Syntax:
AT+WMGO= <loc>
Parameters:
<loc>
The location number of the SMS to write or overwrite. Number depends of the SIM or
Flash memory capacity.
