So I live in jaipur on tonk road. Here speed is very slow because there are too much congestion here due to residential area. Definitely go for jio if you dont want to pay for the services.
So lets talk about Jaipur. So one thing which is very impressive is the nework coverage. I am never out of coverage in Jaipur. Some time ago I visited ajmer and no network issue in my whole journey. Thats very impressive. One more thing I notice about their network coverage is that you will get good network coverage in cities and along the highway. But when I travelling through train. Almost not network throughout the journey.
If I talk about speed what I found is that it has good speed in city area around 15-20 mbps. or wherever there is no residential area speed is good.
My final conclusion is as long as it is free there is nothing to complain because they they are facing lot of congestion. Everything will be decided when they actually start charging customers.
