On the next AT+CMGW command, the record number used will be the one specified by the
AT+WMGO command. The location is forgotten and, in order to perform a second overwrite,
+WMGO has to be used again.
If the external application specifies a free location, and if an incoming message is received
before the AT+CMGW command, the product may store the incoming message at a location

location, the new message will be overwritten!
Note: that this location number is not kept over a software reset.
