I am using reliance 4G from past 4 days, and I am completely satisfied, the average speed which I am getting here in jodhpur, rajasthan is around 42mbps( This is massive), even the broadband connection which I am using at my home is offering just 2 mbps, in 4 days I have downloaded around 700GB without any flaw and that too in very less time, like for example I downloaded a file of 1.22GB in just 1min10secs.
What else can you expect from any service provider, so I conclude with that it is a must have thing to explore the world of internet from other perspective.
