4.2.2 SMS Messsaging
The Modem supports transmission and reception of SMS messaging. To use SMS messaging, you need to configure
a service center address (Phone number). This is done with the AT+CSCA command. To send SMS messages, use
the AT+CMGS command. To receive SMS messages, use the AT+CMGR command. To control the way the modem
reports the arrival of new SMS messages, us the AT+CNMI command.
Note: SMS Messaging is a highly configurable system in the 605M-D1. The following examples assume that all
settings are at their defaults, except for message format which is set to text mode. For more detail on how to use
SMS messaging, refer to ELPRO support for a detailed AT command summary.
