Response
The write / execute command serves to transmit SMS (either SMS-
DELIVER or SMS-SUBMIT) from TE to memory storage <mem2>.
Memory location <index> of the stored message is returned. Message
status will be set to ‘stored unsent’ unless otherwise given in parame-
ter <stat>.
Note: SMS-COMMANDs and SMS-STATUS-REPORTs cannot be
stored in text mode.
If writing is successful:
+CMGW: <index> OK
If writing fails, the error code depends on the current setting of the pa-
rameter <m> specified with AT^SM20 (see Chapter 7.17):
· If AT^SM20=x,1 (factory default):
When writing fails due to timeout: +CMS ERROR: Unknown error.
Otherwise (for example, if a message is too long or contains an in-
valid character): OK
Users should be aware that, in these cases, the message will not
be written to the selected SMS storage.
· If AT^SM20=x,0:
Failure to write a message is always followed by
+CMS ERROR: <err>
For example, if a message was too long <err> code 305 (“Invalid
text mode parameter”) is returned.
