Basic Operations

Preparing the Modem for a Data Connection

Set the APN by issuing the following command where <APN Name> is the APN assigned by the carrier:

AT+CGDCONT=1,"IP","<APN Name>"
Check for registration by issuing AT+CREG?<cr> and wait for the response. If the second value of the response (for
example, +CREG: x,y) is 1, then the modem is registered on the home network. If y=5, then the modem is
registered but roaming. See the AT command reference guide for other possible responses. If the second value is
not 1 or 5, then do not attempt to dial. Wait ~5 seconds for the modem to finish registration and check +CREG
again.

Using the Radio IP Stack to Make a Data Connection

Connect by issuing the command: AT#SGACT=1,1 (using PDP context #1)

Using the Host System IP Stack to Make a Data Connection

This device only supports packet data connections, such as dial-up networking. To make a data connection, you
must use a PPP dialer. If your carrier requires a username and password for the Internet connection, be sure to
enter that information into the PPP dialer. Dial up using ATD*99***1# (using PDP context #1).

Using the Internal IP Stack to Disconnect a Data Connection

Issue the following command to disconnect: AT#SGACT=1,0

Using the Host IP Stack Disconnect a Data Connection

The method to disconnect depends on the type of PPP dialer that was used to establish the data connection.
