I am using Jio since February 2016(employee sim, but I am nat a Jio employee, just got it through referral) and later got one more in july 2016 for a family member. initialy the service were quite good, however as time prograssed they downgraded themselves as the worst telecom provider I have experienced even than BSNL(However BSNL KErala always gave me promp and excellent service). However as of now I just got a few favorable points of Jio
