Reliance jio 4G is one of the best sim for internet.i love this speed its 20 to 30 mbps speed in my city. I was really shocked to use this operator. My friend baught a lyf mobile approx 4500rs and the shopkeeper get a document aadhar card xerox copy for his reliance jio 4G sim, but you take him any document like aadhar card, voter id card and licence etc.
And he waited 2 to 3 days for activating his sim. And when sim is activated than he get unlimited free calling in any network and unlimited internet surfing and downloading.
And its speed so powerfull . I have downloaded a movie in between 15 to 16 minutes of 680mb size.
