Usage guidelines
A SIM/UIM card will be locked in the following circumstances:
• Consecutive PIN modification failures.
• Consecutive failures for enabling or disabling PIN authentication.
• Consecutive PIN authentication failures.
If the SIM/UIM card is locked, the 3G modem cannot be used. To unlock the card, you can use
the pin unlock command. The new PIN is saved on the SIM/UIM card.
If PIN verification is enabled, use the pin verify command to save the new PIN on the device after
the SIM/UIM card is unlocked.
If you consecutively fail to unlock a card by using the PUK, the card will be locked permanently. To
unlock a permanently locked card, contact the service provider of the card.
