I think jio sim is a very bad product because I am using it and not getting call from otherside as well as not able to make calls from myside to others , so many times
Internet is of very worst quality it gives just a speed of .2 or .3 mbps in my area
I personally recommend that untill and unless jio do not get paid dont go for it because free services by jio are not good enough
I am using airtel and beleave me it is superb as compared to jio
Therefor wait till 31st march and use airtel till then
