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 3G carrier for the
PUK in order to unlock the SIM card using your cell phone.
