But in the statement on the support page of Skype, which reads-
“If you’ve bought a subscription to India specifically to call within the country, you can cancel your subscription to avoid being billed in the future.Microsoft owned company Skype had offers to fully refund the users who have made a subscription for beyond November 10. However, Skype calls to other countries are still enabled for India-based users. And users from outside India can make a call to landline and mobile phones in India.
Keep in mind that before 10 November 2014, you can still use your subscription and Skype Credit to call within India, so be sure to use up any remaining minutes or credit you have before then.”
As Skype allows users to make a call on phones via internet, but government regulations do not allow such companies to make internet-based calls originating from India. Therefore, such companies reroute the calls (made by India-based users) internationally, thus circumventing the law.
