This is a good work around but it doesn't solve the root cause. We need this to stop. Net Nuetrality needs to be maintained. Airtel is an infrastructure provider. They cannot charge for different use of the infrastructure - internet bandwidth in this case.

We few people know it could be bypassed. But how will the millions of other users who know nothing about VPNs? Also what if Airtel blocks all these popular VPNs?

Also its not about if we can bypass it or not. It is about what is morally/ethically right and what is wrong.

Free VPN would reduce the speed and quality of the skype call. It would be really hard on a 2G network.
