I am using airtel 4g broadband from three months. This works very well for me since whenever I have wok with my laptop easily connect the wifi and use the internet. Nowadays as 4g network entered there is a lot of improvement in the network speed. But airtel provides the best offers in the internet plans. I will use 8mbps plan @ 650/-. Its uploading speed is good since for downloading a movie it just takes 20-30 minutes. This shows the connection speed of airtel broadband. Easy installation and the customer care is also good.
