I've been using Reliance jio since last 7 to 8 months and it was free of cost back then, only hassel was to get it the sim, initially when the user base was less the network speed was astonishing. ive got used the network on 20mbps speed. and also on slower side 5kbps, which basically depends on where I am! I've been using ₹309 pack, since it had stopped free service. The speed is acceptable and there is also room for improvement.
