17.18.6 Notes
• If the external application specifies a free location, and an incoming message is
received before the +CMGW command occurs, the product may store the
incoming message at the specified available location. If the user then issues an
+CMGW command without changing the location with another +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 +CPMS command, the value of WMGO
will be reset to 0.
