Pros
The latest craze going on now a days is Jio, a new network by Reliance, offering free 4g data, free messages, free voice , and many more. It has various jio apps where you can watch movies, read magazines, listen to songs or even watch love tv. I have been using jio since, october. It is really doing a great job , providing free internet to every. At first everything was free, then 4 gb limit was given for the data. Jio was given till december 31st. Then again it is now extended till march 31st decresing its data limit to 1 gb.
Network coverage - The network coverage of jio is good. Not the best yet, because it gives the network from settelite which doesnot reach each and every place, but the place where I live, I am getting speed from jio and I am happy to have it.
Customer service - The customer service of jio is really very helpful. You call them and in a minute you get there responses and helps you with you every queries. Now a days jio even offer home delivery of sims. You just sit in your home, order the sim and it reaches your doorstep in a few days.
Charger and billings - Till now the charges and billings of jio is absolutely free. After 31st march as I have seen the rechages of jio, they are really low. In 51 only we get 1gb of 4g internet, which is really cheap.
Cons
The network of jio is not so proper is some areas , mainly is some village areas.
