AT+CNMA New Message Acknowledgement to ME/TE, only
phase 2+

The write / execute command confirms successful receipt of a new message (SMS-DELIVER or SMS-STATUS-

REPORT) routed directly to the TE. TA shall not send another +CMT or +CDS result code to TE until previous

one is acknowledged. If ME does not receive acknowledgement within required time (network time-out), ME

sends RP-ERROR to the network. TA shall automatically disable routing to TE by setting both

and

values of

AT+CNMI

to zero.

Syntax

Parameter Description

Parameter required only for PDU mode.
0

Command operates similarly as in text mode.

Notes

• The execute / write command shall only be used when

AT+CSMS

parameter

equals 1 (= phase

2+).

• The execute command can be used no matter whether text mode or PDU mode is activated. The write com-

mand is designed for the PDU mode only.

• If multiplex mode is activated (

AT+CMUX

=0) the

AT+CNMI

parameter will be set to zero on all channels, if one

channel fails to acknowledge an incoming message within the required time.
