Sprint has a unique default PUK number for every mobile SIM. Each phone has a PUK code and inbuilt SIM cards for security reasons. If a person enters a wrong PIN three times, the SIM card is blocked. Thereafter, the phone will ask you for a PUK code in order to reset the PIN number.
The PUK information is highly sensitive and also a proprietary of Sprint which is why customers should contact Sprint customer support immediately their SIM card is blocked.
You can contact Sprint directly using the customer support number and the agents will take care of the problem immediately.
How Do I Obtain a Sprint PUK Code?
It is frustrating when the phone request you for a PUK code and you have no idea where to find it. The moment the SIM card is blocked; you can only unlock it using the Personal Unlocking Key (PUK).
If you still have that pack that came with your SIM, you can find the eight digit PUK code in that credit card sized plastic card. Your SIM PUK is imprinted on the back of that card. Read the PUK and enter it and the SIM card will be unblocked in a few seconds.
Alternatively, you can contact Sprint customer support if you can't find that little pack. Speak to the agent and inform them of your problem - SIM card blocked. The PUK code is tied to your SIM card and the Sprint network.
Therefore, Sprint customer support agents are the only ones who can give you the PUK code. Remember, entering a wrong PUK ten times blocks your SIM card permanently. So, be careful.
Once you have the PUK follow the instructions to unblock your SIM. If that still doesn't work, contact Sprint customer support agents for assistance. Don't enter the PUK ten times as that will cause a serious problem.
Once you have entered the PUK correctly, you will be asked to set your PIN. Ensure you note down the PIN you have chosen just in case you forget to memorize it. This will save you painstaking process of trying to remember it or having the SIM card blocked again. Entering the wrong PIN three times causes the same problem of having to enter your PUK again.
Can I Unlock My Sprint SIM Card If I Have the PUK Code?

It's advisable that you keep the plastic card safe or write down the information somewhere you can retrieve it when needed.
To unlock your SIM, enter the PUK information into the phone when prompted for a PUK. The SIM card is unlocked instantly. Alternatively, you can take your phone to the nearest Sprint store and have the customer representative unlock the SIM for you.
