The offer will be valid till October 31 for all the customers who will need to follow some steps to avail the benefits. Airtel customers can visit the online or offline store to upgrade to a new 4G smartphone. Instantly, they will be entitled to the benefit of Rs 2,000 cashback that will be rolled out in the form of 40 coupons of Rs 50 each.
