1. Locate Your SIM Card Information
The first step is to locate the SIM card information associated with your Airtel account. You can typically find this information on the SIM card holder or on the original packaging that came with your SIM card.
Look for a card that contains the SIM card’s serial number (ICCID) and the PUK code. Keep this information in a safe place for future reference.

2. Contact Airtel Customer Support
If you’ve lost or can’t find the PUK code associated with your Airtel SIM card, don’t worry; Airtel customer support is here to help.
You can reach out to Airtel customer support through various channels. You can also visit a nearby Airtel store in person and request assistance with your locked SIM card.
3. Verification Process
When you contact Airtel customer support, be prepared to provide some information to verify your identity and ownership of the SIM card.
They may ask for details such as your name, address, and the SIM card’s ICCID (serial number).
This step is essential to ensure that the PUK code is only provided to the rightful owner of the SIM card for security reasons.
4. Request the PUK Code
Once your identity is verified, you can request the PUK code from the Airtel customer support representative.
They will provide you with the 8-digit PUK code needed to unlock your SIM card. Ensure that you write down the code accurately and keep it in a secure place.
5. Enter the PUK Code
With the PUK code in hand, insert your locked Airtel SIM card into your phone. When prompted for the PUK code, enter the 8-digit code provided by Airtel customer support.
Be very careful when entering the code, as entering it incorrectly multiple times can permanently lock your SIM card.
6. Set a New PIN

After successfully entering the PUK code, your SIM card will be unlocked. You will then be prompted to set a new PIN for your SIM card.
Choose a secure PIN that you can easily remember, but not something too obvious, like your birthday or 1234.
7. Test Your SIM Card
Finally, test your newly unlocked SIM card by making a call or sending a text message. If everything is working as expected, congratulations!
You’ve successfully retrieved your PUK code and unlocked your Airtel SIM card.
Getting locked out of your Airtel SIM card due to entering the wrong PIN can be a frustrating experience, but it’s not the end of the world.
With the right information and a quick call to Airtel customer support, you can easily retrieve your PUK code and regain access to your SIM card.
Remember to keep your PUK code and new PIN in a safe place, and be cautious when entering the PUK code to avoid any further issues.
By following these steps, you can stay connected and enjoy the services Airtel has to offer without any interruptions.
