When the jio sim is launched not everyone knows about it so the speed of the internet is awesome. But now-a-days when everyone having a jio sim the speed of the internet is not that much its decreases to just 200kb to 500 kb from 2mb to 5mb its the problem and also the call drop on the jio sim is also a big isue now everyone should try it atleast 3 or 4 times so the call is sent otherwise its drop the call.
