How To Unlock SIM Card Without PUK Code? – Unlocking Process

If you forget the PIN and mistakenly input it several times, then your handset is locked, and you have just a way of unlocking it to use it again. If the lock SIM option prompts you to enter the PIN code, and you never changed it, then type the default (you can find this on the SIM Card Holder from which your SIM Card came). If you incorrectly enter the PIN code three times, your phone is locked and requires PUK (Personal Unlock Key) to unlock.

If you forget your PIN code and input it incorrectly 3 times, your mobile phone is locked and can also be locked permanently when the incorrect PUK code is entered a specified number of times.

How to Know if your SIM is Locked?

If you suddenly cannot place or receive any calls or messages, it may be because of a blocked SIM Card. If you have recently acquired a new SIM card, you should have received an unlocking code, the PUK code (also known as a personal unlocking key). These codes are used to unlock a locked SIM card in case its previous operator has locked it for reasons like nonpayment of bills or a final breach of contract.

There are specific security reasons your SIM could get blocked by the network provider, including entering the wrong PIN codes more than once, faking/guessing your charge card PIN multiple times, etc. These reasons might cause network providers to lock your SIM card, which can be unlocked by PUK codes alone.

How to unlock a blocked SIM is one of the crucial information every SIM card user must have, and it is also very important to make sure you maintain the safety of your SIM card package, just in case any situation arises where the SIM is blocked, that could help you easily access the PUK code if needed. Before entering any network provider’s office, you can unlock a blocked SIM using some important info. It is always a good idea to take safety measures to protect your private information; however, remember, in the case of your SIM, you will have to keep both the PIN code and the PUK number handy.

Where can I Get my PUK Code?

You can contact your network provider and get the SIM card unlocked or visit a nearby store and ask them to unlock your SIM card.
