Reliance jio is the best network and it is providing the fastest 4G internet and voice calls are good.Their customer seevice some what dissappoints me may be because of the lag of employees.i am using this since 9 months and I dont face that much problems except some like others calls also connecting to us while we talking with someone.i am using idea since 4 years and airtel since 3 years but they both costs me too much to charge the data and calling , but jio providing unlimited calls and 1GB internet data with 4G speed daily with validity of 84 days.and that to with a most affordable price of 399 rupees.
