Calling Card

Calling Card and phone-card services are very popular around the world allowing people to make low cost international calls from a landline, cellphone or payphone without requiring an Internet connection or data plan.

Calling cards may be pre-paid or post-paid and work as follows:

  1. Customer calls a local access number
  2. Customer authenticated by Caller ID (PINless)
  3. Or prompted for PIN
  4. Optionally, the balance is read out
  5. Prompted for a number to call
  6. Customer connected to called party

The rate the customer pays is far lower than the cost of the same call using either a payphone, the incumbent telephone company or cellphone operator, this is particularly true of international calls.
