Very very poor download speeds. Just displaying 4G or LTE doesnt make a difference Airtel!
For the past two months data has been charged wrongly. Had to call the customer care everytime to clarify them on repeated charging mistakes.
Call drops and poor network coverage are very frequent these days.
Customer care has also become careless. Even though other operators mention as 3G honestly I will prefer them to be ported in; instead of Airtel.
