+CNMA (text mode) set command

The set command sends a new message ACK in text mode. This command can be used only when the modem is activated.

Note: This command can be issued only by a client registered with the +CNMI command.

If the User Equipment (UE) does not get an acknowledgement within the required time (network timeout), it should respond as specified in 3GPP TS 24.011 and the UE/Terminal Adapter (TA) shall automatically disable routing to Terminal Equipment (TE) by setting both <mt> and <ds> values of +CNMI to zero, that is, the SMS client gets unregistered.
