  1. 1 Enter your SIM unlock code. If you locked your SIM card, you will be prompted to enter the password when you insert that SIM into a new phone. If you know the password, enter it to unlock your SIM. If not, you can unlock the SIM with a PUK (pin unlock key) that comes from your mobile provider.

How many digits is a SIM lock PIN?

SIM Security—PIN and PUK – SIM cards allow the user an option to enable security. This is called a SIM PIN ( personal identification number ). Typically the user would use the GUI of the phone to enable the PIN. Some manufacturers have a default PIN value set with new SIM cards.

Numbers such as 0000, 1234, or the last four digit of the cell phone number (MSISDN) are common. Once a SIM has the PIN value enabled, it can affect access to different parts of the operation system on the phone and at a minimum, not allow the SIM file system to be read when it is removed from the phone and examined using SIM forensic tools.

Most SIM cards use a four digit PIN. Others can use five or six digits. To override a lost, forgotten, or improperly entered user PIN, manufacturers also have a personal unlocking key ( PUK ). This is also referred to as personal unblocking key. Both definitions mean the same.

A PUK value is not something a user can enable or change. It is set by the manufacturer. The PUK could be entered to unlock the PIN and allow users to reset their PIN value. PIN and PUK values play into SIM forensics this way: • Only the ICCID value can be read on a PIN-enabled SIM card. • Law enforcement can request the PUK value on a PIN-enabled SIM.

There are some stipulations to getting the PUK through the legal process. The phone associated with the SIM must be allocated. This means if the network terminated or discontinued service to the device, the PUK is generally also not retained. • PUK management can be handled through some forensic tools.

This means that examiners can change the PIN value if they get the PUK without having to utilize the GUI of the phone or assistance from technicians employed by the target wireless carrier.

A PUK is required when you want to unlock a phone.
