I have been using vodafone supernet 4g from last 3 months. Its extremely fast. The download speed in my area is 5 MB per second. What else do I need. I can download a movie of 700 MB in just two minutes. Its great. Watching videos on youtube were never of so ease until using vodafone supernet 4G. Talking of voice clarity, it provides pleasant voice clarity. In terms of network availability, vodafone is excellent in its reach even in remotest areas of my city, I get a pleasant downloading speed. I just love vodafone
