After three failed PIN attempts, which option allows access to SIM data?

• A. Contact Device Manufacturer for a Temporary Unlock Code
• B. Cannot Access the SIM Data
• C. Attempt PIN Guesses After 24 Hours
• D. Ask the Network Operator for a Personal Unlock Number

Answer: (D)

When a SIM is locked after three failed PIN attempts, you need the Personal Unblocking Key (PUK) from the mobile network operator. The PUK is the code the operator issues that unlocks the SIM and then lets you reset a new PIN. The manufacturer does not provide this unlock code, and simply trying PIN guesses later won’t bypass the lock. If the PUK is entered incorrectly too many times, the SIM can become permanently blocked and may require replacement. So the correct path is to contact the network operator to obtain the PUK, unlock the SIM, and set a new PIN.
