Pay attention to that sometimes cards with connection fee have the lowest rates. Take advantage of this circumstance. But first of all, estimate the phone card you have in view. Do it on basis info given by a seller. All you need is to estimate two quantities:
1. Maximally admissible number of phone calls. In case of exceeding this number the calling card loses its lowest rate advantage.
2. Average duration of a phone talk.
Thus, in order to use the lowest rate advantage fully, you must make (quantity # 1) phone calls, which will have duration (quantity # 2) minutes on an average.
Quantity # 2 is critical. If its value is in the reasonable limits and satisfies you, then the phone card is good. If a phone talk's average duration is 150 minutes, for example, then reject this card and view other variants. You can be guided by quantity # 1 when using the chosen prepaid calling card with the largest advantage.
Note: average duration of a phone talk does not depend on a nominal price of card, and the number of phone calls depends. It means that the price does not influence on the estimation result.
