How Does a Sim Unlocking Code Work

You turn ON your phone one day, and the screen shows up just as usual. Then you open your messages, select a recipient, type the message, and press the SEND button. But wait, it does not send but shows up a message failure note. You just avoid it, open your contacts, select the one you had to contact and try to call but again, and you are not able to do so!

Wonder what’s wrong with your phone? In reality, there is nothing wrong with your phone; it is working perfectly fine. The entire problem is with the sim card! Not the problem, but it has been locked to prevent any unauthorized use.

You do not have to worry, we have got you covered. You will read about How to unlock using: Sim Network Unlock Pin and Master Code below.

To send messages and make phone calls, you have to unlock your sim card, by entering a four-digit number that is abbreviated as PUK. In some parts, it is known as Pin Unlock Key while in other it can be called as Personal Unblocking Key.

Your phone will ask you for the pin code, and this PUK has to be entered that you would have been given at the time of purchase. In case you do not have it you can call your network carrier or visit them to ask for this code.

Once you have the code in your hand, all you need to do is enter it when the phone turns ON and asks for it. Once the correct code has been entered, your phone will turn on and start working.

In case the wrong code has been entered, you will be asked to enter again. Each user has three chances to enter the code. In case someone fails all three times the phone is locked, and you then have to go and get yourself verified before getting the pin again that can unlock your phone.
