How To Compare Calling Cards
This may be a hard task. For example, how to compare two cards? One of them has high per-minute rates and low fees. Another has low rates and high fees.
Here is more concrete example:
Talk USA card has a lower per-minute rate. World Access card has lower fees. What card is better?
The comparing task might be simplified by using only one integral parameter that would count up both rates and fees.
Phone call time limit you get with a calling card is exactly that parameter! It counts up all fees and rates. It is simple, clear, and understandable. With this only one parameter, you can more confidently compare calling cards each of those has many hard-to-compare features.
You can calculate phone call minutes with our special tool. Let's turn to the example above and load its data into it.
We'll see the following result:
Now to compare these cards is simpler. As we can see, with Talk USA card, you'll get more phone call minutes than with its competitor.
You also can easily calculate an effective per-minute rate (i.e. what you really pay for each minute of a phone talk). Simply divide a card price by the calculated minutes. As we can see from the same table, the World Access card has lower effective per-minute rate than its competitor.
Let's note that rates and fees together define the cost of calling. So here we actually estimated calling cards on that base.
I foresee the possible objection: a cost of calling is not enough to compare calling cards. Such things as voice quality matter much more. I can reply: that's another article. And the cost of calling is, of course, not enough but it's very necessary.
