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 2306,1,“myAPN.myOperator.com”
AT$APP PARAM 2314,0,“myUSername”
AT$APP PARAM 2315,0,“myPassword”
For a blank APN the following command can be used:
AT$APP PARAM 2306,0,“” (for a blank APN)
Only enter this next command if you have been given a non-zero PIN as any errors may lock you out
of the modem.
AT$APP PIN <SIM pin>
You can confirm activation by watching the Comm LED to see if it goes solid. You may also confirm
activation using
AT$APP COMM STATUS?
