Reliance Jio have started booking of this phone. This phone is going to be a boom in the Indian market.
Network:- This should be a big concern of this phone, because its targeted towards the people of rural areas, and those who are not been able to buy an 4G Smart phone. In rural areas Jio needs to improve their network quality.
But in cities or city surrounding Jio has done a lot of improvement.
Customer Service:- Customer Service of Jio is not been tested yet, because, for the one year Jio is providing their services for free.
Charges and Billing:- Jio is the most cheapest 4G net work in the world(as per my concern) . Its so pocket friendly, and this phoe is almost free to the customers, though Jio told that tey will return the security deposit ammount to the customer after 3 years.
