I am using vodafone since last 2 years and my experience on the vodafone supernet 3g is very good and then I know about the new vodafone 4g and I like to try it and I really like its speed and network coverage.
Network coverage-:
Vodafone gives a wonderful network coverage to all of tgeri customers even in the village area I got full network and a wonderful network experience in roaming also.
Internet downloading speed-:
Vodafone 4g gives about 4mbps downloading speed in my area which means you can easily download 4mb in a single second and you would be able to download a 1gb movie within 10 minutes which is very fast speed as compare to other 4g networks.
Internet uploading speed-:
Vodafone 4g gives a 2mbps uploading speed in my area which means you can easily upload anything on web with the speed of 2 mb per second which is also a wonderfull speed as compare to the other 4g companies.
Overall if u want a high speed internet and a good network coverage also so you must have to go with the new vodafone supernet 4g.
