Yeah investment, because most the time we saw some pathetic speed in 3G also. Airtel 4G is so pathetic that except 4G noting can differentiate between other generation.
Also I am not blaming any Telecos they got open opportunity to loot people hence keep on increasing data packs and all other services prices by the name of infrastructure.
According to the latest "Call Drop" complaint Airtel is leading having most number of complaint then anyone else. They're front runner of anything talks about Free Internet under Airtel Zero and other hand keeps on increasing Data Tariff in every 2 months and Govt. is sitting idol rather then penalizing them
