If you’ve lost your phone or misplaced your SIM card and can’t seem to locate it, blocking it might be a good idea to avoid anyone else from misusing the SIM.

While eSIMs are becoming a trend in new smartphones, if you’ve misplaced your phone or SIM card, here is how you can block your Airtel SIM card in a few easy steps, followed by a guide to replace or unblock your Airtel SIM card.

Blocking Airtel SIM card

You’ll need to contact the Airtel Customer care on the number mentioned below.

  • Dial 121 if you’re using a Airtel mobile or landline number.
  • Dial 9810198101 if you’re using a non-Airtel number. You can alternatively also try calling on 18001034444 from non-Airtel number.

When speaking to the customer care executive, you’ll need to answer a few questions to verify your identity, including your full name, address, date of birth, among others.

It’s also a good idea to keep the documents (Driving License, Aadhaar Card, Voter ID Card, PAN card or Passport, among others) that you shared with Airtel at the time of buying the SIM card alongwith you to make the process quicker and block your Airtel SIM card without delay.

Once the customer care executive has verified your identity and take down your request, your SIM card will be blocked within 72 hours. In some cases, it can even take a week to block your Airtel SIM card.
