The last item an operator may provide is a SIM PIN. The PIN is effectively a password to
the device. The main difference here is that the PIN will restrict all the capabilities of the
GSM device, where the SPC is used just for configuration.
The activation sequence for a GSM LMU would therefore look as follows:
AT$APP PARAM 2306,0, “myAPN.myOperator.com”
AT$APP PARAM 2306,0, “” (for a blank APN)
AT$APP PARAM 2314,0,“myUSername”
AT$APP PARAM 2315,0,“myPassword”
Only enter this next command if you have been given a non-zero PIN as any errors may
lock you out of the modem.
AT$APP PARAM 1285,0,<SIM pin>
You can confirm activation by watching the Comm LED to see if it goes solid. You may
also confirm activation using
ATIC
