What exactly is the PUK code and why is it important to know it to unlock our mobile phone?
The code PUK (Personal Unblocking Key) is an 8-digit security code that is used to unlock our SIM card if it has been blocked due to incorrectly entering the PIN code on multiple occasions. It is important to know it, since without it, we will not be able to regain access to our SIM card and will need to purchase a new one.
When we enter the PIN code incorrectly three times in a row, the SIM card is automatically blocked as a security measure to prevent unauthorized access. At this point, we will need to enter the PUK code to unblock it and be able to continue using our mobile phone services.
The PUK code is unique to each SIM card and is usually printed on the card or the document that accompanies the SIM when we purchase it. It is also possible to request it from our telephone service provider if we have lost it or do not have it at hand.
It is essential not to confuse the PUK code with the PIN code. The PIN is a personalized 4-digit code that we can configure to protect access to our mobile phone and that we must enter every time we turn on the device. The PUK, on the other hand, is a security code specific to the SIM card that we only need in case it is blocked.
In short, the code PUK is essential to recover our SIM card if it has been blocked due to errors when entering the PIN. Therefore, it is important to keep it in a safe place and have it on hand in case you need it.
What are the most common situations where a PUK code needs to be unlocked and how can we avoid accidental blocking?
The PUK (Personal Unblocking Key) code is a security number used to unlock a locked SIM card. The most common situations in which a PUK code needs to be unlocked are:
1. Incorrect PIN entered:When we enter the PIN of our SIM card incorrectly three times in a row, the mobile phone will request the PUK code to unlock the card.
2. Accidental handling: Sometimes, when handling our phone without realizing it, we can enter the PIN incorrectly, leading to a SIM card lock and the need to use the PUK code.
3. Unauthorized access attempt: If someone tries to access our mobile phone without our permission and enters the PIN incorrectly, the PUK code will also be required to unlock the SIM card.
To avoid accidental blocking and the need to unlock the PUK code, we can follow these tips:
1. Memorize the PIN: It is important to remember our PIN correctly to avoid entering it incorrectly repeatedly.
2. Avoid unnecessary manipulations: Care must be taken when handling our mobile phone to avoid pressing keys by mistake and blocking the SIM card.
3. Establish additional security measures: To protect our device, we can use security methods such as fingerprint, facial recognition or unlock patterns, thus avoiding the constant use of the PIN.
4. Save the PUK code in a safe place: In case it is necessary to use the PUK code, it is important to have it on hand and stored in a safe place to be able to unlock our SIM card quickly.
By following these tips, we can minimize the likelihood of accidentally blocking our SIM card and requiring the use of the PUK code.

The PUK (Personal Unblocking Key) code is a security number used to unlock a mobile phone in case we have entered the PIN code incorrectly on several occasions. Below are the steps to correctly obtain and use the PUK code to unlock our device:

It has happened to me 10 times and I managed to restore the wifi signal but blocked access to the cell phone. I tried or executed the other alternatives such as factory settings from the volume and power buttons on the device. But there is no great progress although they left the chip as new but still blocked. In addition, there is no longer a wifi connection with the cell phone. I must visit the store and replace the card or chip but how do I keep my cell phone number?
