The most commonly used network in todays world is reliance jio.i have been using this network for 1 yr and so I am giving review on this.
Network-
When we talk about network, it is good.for calling the network is available almost all over india and because of its unlimited calling, it is mostly preffered.now talking about 4g network for internet it is only available in good speed at night time.other wise during day time, the speed fluctuates and most of the time it is lowest( somewhat in kbps) which is too frustated.
Customer service-
Jio provides a good customer service.it always recieves the call for any help and responses to the problem immediately.
Charges-
The most commonly used plan of jio is of ₹399 which provides 1.5gb per day and unlimited calling for 3 months.so when we talk about charges, jio has the best plans for middle class people.it has more lowest charged plans which are very good.
Overall I would say u shud go for jio for reduced rates but for 24×7 high speed, its not feasilble.
