Step 1: Get a new 4G Airtel SIM and you’ll automatically be eligible for Airtel double bonus data offer or send Get to 141 to activate the offer.
Step 2: Simply subscribe to your desired data plan after a successful response from their double bonus activation center
Step 3: Now, dial *141# to purchase any data plan of your choice using your 4G Airtel SIM card. Your purchased data, bonus data, 4G bonus data will all be given to you.
Step 4: Within 24 hours of data purchase, kindly reverse the data by dialing 1216#, select the amount of data you previously purchased that you want to reverse and then, your money will be restored back to you.
Step 5: Simply subscribe again with your reversed Airtime and use only the bonus data only. Keep repeating the process if you want more data.
The trick works well on both Airtel 3G and 4G SIM cards and one more thing, do not subscribe on any data that has a night bundle.
That's it guys. Kindly share to friends and loved ones.
