I am using Reliance Jio for the last one year. I am really happy with the product and I even disconnected my other two connections with RIM. In some areas there are some issues of signal strength and 4G to 3G to 2G etc. But so far I am happy at all.
But I also have a doubt about the tariffs, day by day the schemes are changing like 300/-3months to399/- 84 days to 199/- -28 days. This is I think make people think about Jio. Please take it positively.
