A lot of people travel across the world or have business or family relations abroad. This require calling from India as well as calling to India when they are abroad. There are different kinds of calling cards present in the market and these can be used to lower the cost.
World calling card
This is a card that is used by a person when they are in India and they want to call someone abroad. Using a normal phone or a mobile phone can raise the cost for the person but these cards allow for calling to specific countries at a lower rate. This is very useful for someone who has to call relatives or business contacts on a regular basis where in some cases the call is as cheap as a STD call.
India calling cards
These are phone cards that can be used in other countries to call India. They allow for calls to the country at a cheaper rate than what would be the cost otherwise and the person can buy these cards for a specific country. This ensures that there is an opportunity to call back home and that too at an affordable cost because using international roaming can be very expensive.
