Today Jio is a leading mobile operator in India, there are more than 10 crore users of Jio digital in India. It is the first mobile operator in India to provide free internet service for 1 year. But in my opinion Jio is not the best mobile operator.
Jio have lot of network issues, it has the worst network after aircel, Internet speed of jio is very low as compared to Airtel. Customer Service provided by the company is not too bad its just like the other mobile operators. Charges and Billing of all the mobile operators are almost same, everyone is providing unlimited calls and 1 GB/day data to their customers.
Jio should first setup its tower all over India properly and should provide better internet/Browsing speed as they were providing earlier.
