How to unlock a mobile without knowing the PIN
Here are the most common ways to unlock your mobile without knowing the PIN.
Unlock a mobile using the PUK
If you do not remember your PIN, it is most likely that in order to access your mobile for just a few seconds, you must resort to the PUK code. This code consists of an 8-digit sequence that is usually found on the SIM card, so if you want to continue using your mobile, you must extract it to see these digits.
When you extract it, you will realize that, in one part of the card, there will be the PIN, made up of 4 digits and the 8-digit PUK code. The one with the most digits translates as Personal unlock key o Personal unlock code. If you tried to unlock your phone and you already reached 3 attempts, your phone got locked and you won't be able to do anything anymore.
You cannot change the PUK, if you think you cannot remember it, you should write it down on a piece of paper and call the operator. You must provide some information about yourself, such as ID, name and surname, among others. Keep in mind that it is a personal and non-transferable code.
