Application Started
To use IP data services, you need to configure an APN. Your cellular account needs to
have data services, and the cellular provider must provide you with an APN string.
Example: Enter AT$CGDCONT=1,"m2m.apn.com" to set the APN.
The APN string: "m2m.apn.com" is a sample. Do not use.
Note:
Use AT+CGREG? to verify GPRS registration.
AT+CGREG?
+CGREG: 0,1
OK
A response with 0,1 indicates that your device is registered on the GPRS network. A
response of 0,0 would indicate not registered. Once you are registered, Courier M2M
will automatically activate a PDP context. Enter AT$IP to verify the device's IP address.
