Surely after using Jio sim for little over a month, it surely is worth using for the internet speed. The restriction of 4gb seems to bother a little but it can be overlooked. I would like to say don't believe in the fake videos that are in the Youtube which claims to remove 4gb restriction cause believe me I tried all the methods.
There is another drawback about the sim that is the calldrop rate. Though the company claims to have solved most of it I still face the call drops a lot. By a lot I mean from the ten calls I only get 1 connected and other 9 is dropped and sometimes all 10 calls get dropped. And its a very sad thing. But I found a solution for it and my calls get connected thanks to its internet speed. As most of my friends use Viber, Skype and Whatsapp I call them there instead of using normal dialer but it may not look a permanent solutions to most people that's why I rate this a little lower.
