Here are some ways to check your Airtel prepaid balance on your mobile:
Use the Airtel Thanks app
Download the app from the Google Play Store or Apple App Store. Log in with your Airtel number and OTP, and then go to the home screen to see your balance. You can also use the app to check your data balance, active plan, and validity.
*Dial 123#
From your dialer app, dial *123# to see a pop-up message with your balance.
*Dial 121#
Dial *121# from your Airtel mobile number to check your data balance. This is free and won’t use your data allowance.
USSD codes are a popular way to check your balance because they don’t cost extra, don’t require an app, and don’t require an active internet connection.
