How to check mobile data balance in airtel?

I reckon the easiest way is the Airtel Thanks app. You just open it and your data is right there on the main screen. Super simple. If you don't want the app, you can dial a code on your phone. Try dialling 121# or 123#. One of them will definitely show you how much data you have left. It usually pops up on your screen straight away. Hope that helps you out, mate.

To check your Airtel mobile data balance, the easiest method is using USSD codes. Just dial *121# and follow the on-screen menu. Alternatively, you can dial *121*2# directly to see your data balance. This works even without internet connectivity, making it reliable if you just want a quick check.

If you’re comfortable with smartphones, the Airtel Thanks app is more convenient. After installing it from the Play Store or App Store, log in with your Airtel number. The home screen shows your remaining data, validity, and other offers. I prefer this because it updates in real-time and also gives data usage insights.

For prepaid users like me, I often rely on IVR calls. Just dial 198 or 121 from your Airtel number and follow the voice menu to check data usage. It’s a little slower than USSD but useful if you prefer listening to the instructions rather than typing.

You can also check your balance by sending an SMS. Type DATA USE and send it to 121. Airtel will reply with your data balance details. This option is good if you don’t want to use USSD or apps but still need the info in writing for later reference.

I’d recommend checking data regularly because Airtel packs can sometimes renew silently. By monitoring through the app or *121*2#, you’ll know if data is being consumed abnormally, maybe due to background apps or automatic updates.

Some modern smartphones with dual SIM support can track Airtel data automatically. For example, on Android, you can go to Settings → Network & Internet → SIM cards → Data Usage. While this doesn’t show Airtel’s official records, it’s handy for personal monitoring alongside USSD or the app.

If you’re traveling abroad with an Airtel SIM, it’s better to use the Airtel Thanks app with Wi-Fi. Sometimes USSD codes don’t work on international roaming. The app connects securely and shows data pack usage without issues. I’ve used this while in Dubai, and it worked fine.

In my experience, the Airtel Thanks app is best for postpaid users. It not only shows the remaining data but also breaks down family sharing, rollover data, and bill cycle information. This level of detail is not available through simple USSD codes.
