If you are using a 4G mobie then trust me jio gives the best service for that . Price for internet is really very cheap. Jio has come with a revolutionary change in mobile network industry.
Call price are zero and sms are also free.
If you are using Jio, its a big no to rechagre and excuses for not to call some one.
Speed is good but overall servises are taken in consideration, its a good one.
