Chapter 3: AT Commands Reference
+CMGS, Send SM to Network
This command sends an SM from the H24 to the network. The message reference value is
returned to the H24 upon successful delivery of the message.
Valid will be any value between 128-255.
The header parameters in TEXT mode will be set according to CSMP settings.
Note: Any character sent by the TE to the H24 before H24 has reported a result of AT+CMGS
operation, will abort AT+CMGS command execution. However, if SMS was already sent
to network and sending operation was successful, the result of operation "+CMGS "
will be reported by H24.
If after aborting AT+CMGS command execution and before result of operation was
reported by H24, a second AT+CMGS command is executed, then the result of the second
AT+CMGS operation only will be reported by H24.
