Here’s another working trick for postpaid subscribers of Airtel but it might be limited to selected customers. To get this offer on your sim, you have to login into ‘my airtel app’ using valid postpaid number. Then you will see the banner claiming free 60GB 4G data. If it asks, download ‘airtel tv’ app too.
Now get ready to enjoy 10 GB/ month for next 6 months. Alternately, you can send message SURPRISE to 121 for availing the same offer.
