Reliance Jio is the first ever mobile operator to provide unlimited net services and calling at no cost, but for a limited period.
As of all others, I bought a Jio sim. The internet service was quite fast during the start, but due to exponential increase in the users, he speed dropped to half of it used to. Jio provides the worst calling and network services. Limited range and mid-disconnecting calls are some of the worst drawbacks of the Reliance operator.
Jio Prime provides the same services for 303Rs a month. 10Rs a day with service this bad, I’d advice you getting back to your initial sim service.
Jio did work smoothly for 2-3 months during the beginning but has offered a constant degrade in quality.
