PUK Code to Unblock SIM Card
Have you accidentally blocked your SIM card? Well, all you need is a PUK code to unblock SIM card, which is furnished by your service provider so that your SIM can operate again.
The security features of your mobile phone are a great way to safeguard your cell phone and its contents. However, these features can become a cause of trouble for some. Why? Because, if you enter a wrong PIN (personal identification code) or security number 3 times, either your SIM card or your cell phone gets blocked. This is one of those cell phone safety features that might frustrate you at times. In such a case, you will have to either purchase a new card or a new phone, or you will have to get a PUK (personal unblocking key) code.
The number of times a PIN can be entered before the SIM card or the phone gets blocked differs from phone to phone. There are various ways to unblock a SIM card that has been blocked as a result of error while entering a PIN or security code. Some of the methods of obtaining a PUK code have been discussed below.
How to Obtain a PUK Code?
The PUK code to unblock SIM card is an 8 digit number that is unique to your SIM card. In order to unblock the SIM card, you will have to use the PUK code once, and you will be given 10 attempts to get the code right. After the code is entered properly, the card or the cell phone gets reactivated.
The easiest way to retrieve the PUK is to visit the official website of the service provider. The Vodafone PUK code can be obtained directly from the company’s website. Often, the mobile phone also blocks the SIM card if you enter the wrong PUK code. Motorola is a fine example of such a handset. If you enter your PIN incorrectly thrice, then the phone gets blocked, and you will see the word “Blocked” flashing on the screen.
In such a case, you will have to contact your service provider or visit their website for the PUK Code. Nokia handsets will flash “SIM card blocked – Enter PUK” if you enter the wrong PIN. Blocked SIM cards often have to be replaced. For example, if you have a Nokia handset, then you will see the words “SIM card rejected”, indicating that you will have to replace your SIM card.
There are three principle channels with the help of which a service provider enables a consumer to retrieve the PUK code. The first and the easiest one is to obtain the code directly from the official website of the handset manufacturer or the service provider. However, this channel has been previously used for unethical and illegal motives, as such a system does not have a legitimate identification system.
The second method is to contact your service provider via an email. This method is quite reliable, as, upon contacting the service provider, the company runs a simple background check by cross-checking your email identification and other elementary details, such as your credit card number, account number, etc. Thus, sending an email is a preferred way to get the PUK and such a channel is gaining widespread importance due to the fact that it protects the user’s interests and prevents identity theft.
The last method is to contact the call center. This is also quite safe and a quick method to get the PUK code. During the call, the call center executive will perform a quick identity check, thereby blocking any unethical activity.
The fastest way to obtain a PUK code is by using the call center method. If you want to be cautious, then emailing them is also a good option, but it takes quite some time for you to unblock the SIM card that way.
