Reliance JioFi is a gift given by Reliance company to the Indians. Specially middle class families are very glad to have this. People who have recently purchase a 2g-3g mobile and not able to spend more money to purchase 4g mobiles, Jiofi is great for using 4g data and free call service anywhere in India. A qunique idia by reliance is praiseable.
As compare to Airtel it is very good quality in service in very cheap rates. A very good thins is that people who did not know hoe to internet is work, are presently linked with whats app, facebook, e mails etc. Its speed is very good. I have purchased a connection Jan 2017, after purchase of this I never paid any money for data usage.
