When it comes to the Jio service, a lot has been said about rampant call drops and failed connections, but here is the good news- Jio 4G certianly lives up to its promise of offering lightning fast speeds, especially outdoors. I tested the service extensively in Mumbai, Pune and Banglore and was impressed with the results. Even on the highways between Mumbai, Pune, Banglore and Mysore the data speeds were very impressive ranging from 2mbps to 35mbps which is more than enough to get the job done on the go.
