Have you accidentally locked your Airtel sim and are looking for the solution? Well, in that case this article can help you.

If you lock a sim then it doesn’t bother much unless the phone is restarted and you see that the phone is asking for a code and it is locked. When this happens, you can’t use the phone for anything until you unlock the sim.

Well, in these typical situations, first we have to look at why it happens and what type of code will work on it.

So, let’s take a look at all of these and after that I will show you how you can unlock your locked sim in different ways.

For fast reading, take the help of the table of content given below.

What is Airtel PUK Code?

PUK which is also known as Personal Unlocking Key, is a feature in mobile phones to protect the sim information which is stored by the user.

It is very similar to phone locks which we use in our smartphones to protect our data.

This comes in handy when your phone is stolen and you want your sim data to be protected so that no one can access it and extract information from it.

But the catch is that, if your sim is locked and you enter the wrong pin 3 times then your sim will get temporarily blocked. Now this sim will ask for PUK code.

But if you again entered the wrong PUK code 10 times then the sim will get permanently locked and hence it will be impossible to open it again.

In those cases, a new sim is provided with the old sim number.

Airtel Default Sim Pin Code

Most of the pins come with an inbuilt pin of a 4 digit numerical string. If you have not changed the original one, then you can unlock it by entering that.

In most cases, the default pin of the Airtel sim is either 1111 or 0000. Both are given 4 digit numbers.

Many people change this original pin code so that it is more secure. You can also do it by using the inbuilt settings of your phone.

  1. Go to mobile Settings > Security.
  2. Enable the lock sim card option.
  3. Here, it will ask for a new pin.
  4. You will have to enter it again for confirmation.
  5. Once done, the sim will get locked.

You can also do it using a specific ussd code which makes it quite easier but it is confusing. Here is the code for it:

**04*Original Pin*New Pin*New Pin#

Remember that both pin codes should be a 4 digit number.

If you are not familiar then I won’t recommend locking your sim card unless necessary. Locking the phone entirely is a much better option in many cases.

Methods To Get Airtel PUK Code

To help the customers in urgent situations like this, Airtel has provided many official ways to get the PUK code.

All of these are working and if one somehow doesn’t work for you, then take the help of other methods.

Get Airtel PUK Code By Calling On Airtel Customer Care Number

In this scenario, contacting Airtel customer care can help you a lot. Below I’ve provided 2-3 ways to contact the Airtel support. If one number doesn’t work then keep trying on the others.

S.NoAirtel PUK Code Customer Care

2.198 or 123

Talk directly to customer care executive

This is the general customer care number- 111 and 121 of the Airtel network. You can call there and find out the puk code of your sim:

  • Open calling application on your device.
  • Dial 121 or 111 in the dial pad and call on it. 
  • An executive of Airtel customer care will connect to you and they will ask your problem.
  • Now tell them that you want to know the PUK code of your sim.
  • Firstly, they will verify by asking for personal details such as Date Of Birth (DOB) or Aadhar card number in some cases.
  • Once you are verified, then you will be provided with the PUK number.
  • Now, you can use it for unlocking your sim.

Note: You can use another number which is 12150 to connect with the customer care staff directly. All of these are toll free numbers so don’t worry about any balance deductions.

Call on 198

If you don’t want to talk to the customer care agent then you can try this automated help number for Airtel.

  1. Open the dial pad and call on 198.
  2. Choose your language by pressing the appropriate buttons.
  3. Now, you will hear the complete menu from the IVR
  4. Once the PUK option comes, choose it by typing the option number.

What to do if you don’t have another Airtel number?

All of the above two methods will only work if you have another Airtel number. If you don’t have one then you can’t use the official Airtel customer care numbers.

That’s why for non-Airtel users, there are some other numbers through which you can contact the Airtel customer care.
