Every single private sector mobile company has hiked their charges. in fact their leadership had made it clear..they are now out to make money and accumulate funds for shareholder returns expansion, upgrades. We better get used to it unless you want companies to shut shop and we will all suffer at the hands of duopolists.
Compared to what people in other countries pay, Indian telecom charges are a dream. If you want cheap recharges go to BSNL and suffer the poor quality service. My father in law, a decades long customer of BSNL, finally shifted to Airtel. It was impossible to dial his number as I think BSNL is shutting down towers/transceivers to save money.
I use all 3 pvt. sector operators and Jio is still the cheapest even if marginally. Vi the most expensive.
