Activate SIM PIN lock to protect your SIM card from unauthorised use; How to get PUK Code to unblock your SIM card?

The majority of smartphone users may have experienced SIM card blocking or rejection difficulties as a result of entering the incorrect PIN or PUK while adjusting their phones’ security settings.

Users of smartphones typically set up password, face, fingerprint, and pattern locks to secure sensitive information kept on their devices. But what security measures can we take for the data on our SIM cards? Because our cell numbers are already connected to our bank accounts, Aadhar numbers, billing information, and transaction OTPs, our SIM card data is more sensitive.

Increased Security using a PIN-Coded SIM Lock feature.

Enabling SIM Lock on your phone is the only way to safeguard data kept on your SIM card. The purpose of the PIN (Personal Identification Number) code is to prevent unwanted usage of your SIM card. After you activate the SIM lock function, your smartphone will prompt you to enter your SIM PIN each time it restarts or you switch SIM cards, and your SIM card won’t work at all without authentication.

How to Enable SIM Lock Facility?

Select Security or Passwords & Security by going to Settings.

Select Privacy, More Security Settings, or Other Security Settings by tapping on them.

Then, to set up SIM card lock, tap on the appropriate SIM card.

To activate the SIM card lock, enter the PIN now.

Default PIN code

For both prepaid and post-paid BSNL Mobile users, the default PIN is 0000. It is usually advised to modify the default PIN. You input the changed PIN directly into your phone, so no one can ever locate it.
For the default PIN code for other private operators, such as Airtel, Jio, and Vi, please call the customer care lines of the relevant telecom service providers.
How can I modify my SIM’s default MPIN?

Change SIM PIN Option

What should I do if I input the wrong PIN and block the card or forget my PIN?

Your SIM card will get banned after three incorrect PIN entries, and it will request the SIM PUK (Personal Unblocking Key) code in order to be unblocked. The only way to unlock a SIM card that has been blocked because of an erroneous PIN is to input the PUK code.

The PUK code is an eight-digit code that may be obtained by calling the toll-free customer care number or the local BSNL customer service center. You might need to provide the customer care executive with your SIM card number (19 Digit Number written on your SIM card) in order to obtain the PUK code for your number.

Once you’ve input the PUK code, the phone will ask you to enter a new PIN (Personal Identification Number). We suggest choosing a different PIN code instead than the default 0000. The new PIN will then need to be entered once more for verification.

SIM Rejected due to Incorrect PUK Code

Ten times, you can enter the correct PUK code. After then, the card will be fully blocked and you won’t be able to use it any more. When a SIM card is banned by the PUK code, it can never be unblocked and used again, hence it needs to be replaced.

How long would it take to unlock a BSNL phone that has been banned by PUK?

Once you enter the correct eight-digit PUK code, your prohibited BSNL SIM card will be automatically unblocked. All you have to do is get your PUK code from the nearest BSNL Customer Care Representative or BSNL CSC.

What fees are involved in obtaining a BSNL PUK code?

The BSNL PUK code is free of cost. For the BSNL SIM PUK code, get in touch with the local BSNL CSC or customer service.

Is there a difference in procedure between BSNL Post-paid SIM and Prepaid PUK Code services?

Both prepaid and postpaid mobile users must follow the identical steps to obtain a BSNL SIM PUK code.

Is it feasible to get the BSNL PUK Code by text message?

No, it’s not available right now. The only way to get a BSNL PUK code is to speak with a BSNL Customer Care Executive or CSC.

Can someone obtain a BSNL PUK code without a SIM card?

BSNL PUK codes cannot be obtained without a 19-digit SIM card number. If your SIM card is missing, you can obtain a duplicate or replacement SIM card at the BSNL Customer Service Center (BSNL CSC) that is closest to you.

Please, dear readers, spread the word to your friends and family about this important information. How many of you have received complaints regarding PIN or PUK codes? Do you think that turning on the PIN lock feature will safeguard your SIM card from being used without authorization in other phones?
