Jio has speed but not work in my area, I live in front of Malpura Gate, Sanganer, Jaipur, Rajasthan
I only use jio sim when I go to our park(sanganer stadium) in evening. That 1 hours I use this Network. At part, I works very smoothly, no latency, no video buffering. very good.
But my area has some technical issue.
I compliant a lot of time to their customer care but only "aaswasn" comes from there
Taking about Charges - I brought this sim in 99 rs at our local canopy. Right now it is completely free . let see when they will charge their free customers.
