As per the recent amendment made by the telecom regulator TRAI, mobile users will now have the freedom to choose any operator for making long distance calls, whether domestic (STD) or international (ISD) irrespective of their subscription to a particular service provider.
So, suppose you are a Vodafone subscriber and you find out that Airtel is offering the cheapest long distance tariffs, you can simply buy a prepaid long distance pack from Airtel for a specific time duration, punch in numbers mentioned on the pack, get on to the Airtel network and make your long distance call.
This whole thing of using virtual calling cards to make long distance calls works out in three simple steps:
- Buy a prepaid virtual calling card of your desired operator
- Punch in the calling card code on your mobile handset
- Use STD/ISD services of the new operator
