SIM PIN Error
Note: In the case of SIM PIN Error, the device will check the AT$SPIN every 10 minutes and try to
access the SIM again. The PIN will be validated 3 times and if it fails the last attempt, including the first
inserting time, the SIM card will be locked. Once the SIM is locked, you need to contact your GSM
carrier for the PUK in order to unlock the SIM card using your cell phone.
