• The incoming SMS/CBM URC indications will be displayed only on the AT interface where the last +CNMI

o After start-up
o After using the Z and &F command (which reset the command configuration)
o Whenever the incoming SMS URCs indications are requested on a different AT interface
• <mode> = 3 is not supported.

9.8.1î™–î™–î™–î™–Description
Returns the message with location value <index> from message storage <mem1> to the DTE.
The parameters <tooa>, <fo>, <pid>, <dcs>, <sca>, <tosca>, <length>, <cdata> shall be displayed only if
+CSDH=1 is set.
The syntax AT+CMGR=0 allows to display an SMS class 0 if it is signalized to MT, because no MMI is
available in the MT (see also the +CNMI AT command notes).
If the <index> value is out of range (it depends on AT+CPMS command setting) or it refers to an empty
position, then "+CMS ERROR: invalid memory index" error result code is returned.
