what is the puk code
A PUK code is the Personal Unblock Key code used to unlock a cell phone after being locked out due to entering an incorrect PIN code a certain number of times. The Alcatel PUK code is an eight-digit code given by the service provider and cannot be changed, and the SIM card can be damaged if an incorrect PUK code is entered. If the PUK is entered incorrectly, a new SIM card, along with a new PUK, needs to be obtained from the service provider to unlock and use the phone.
