• Connection Fee: Also called first-minute surcharge. It’s charged when a telephone call is connected. It varies between 25 cents to as high as $3. The easiest way to evaluate whether a cheaper calling cards with connection fee is worthwhile or not is to estimate the average time for your phone calls. If you make 10 mins calls, a card for 5 cents/min with $0.50 connection fee is actually more expensive than a card for 9 cents/min with no connection fee. It’s better to use a phone card without connection fee if you are not sure the person you are calling is there, and the phone call may trigger an answer machine. Phone cards with high connection fee is good for the case when you know your party is there and you intend to talk for a long time. 
• block increment: This is the basic unit to record the length of your phone calls. Industry standard is one minute rounding, as in the case of your residential telephone services. Prepaid phone cards can be rounded to one, two, or even three minutes. If it rounded to 3 minutes, your 30 seconds phone call will be considered as 3-mins phone call and your 4 mins phone call will be considered as 6 mins phone call. Statistically, on average, for 2 mins rounding, you will be charged for one more minutes for each phone call, and for 3 mins rounding, you will be charged for one and half more minutes for each phone call. So try to avoid using calling cards with more than one minutes rounding.
• Pay-Phone Surcharge: Prepaid phone cards provide the most convenience when you want to make cheap phone calls anywhere, but there is usually a surcharge between $0.30 up to $0.75 associated when you use a public pay-phone. Payment for the use of a public pay-phone is required by FCC. However, from the variation of this surcharge, it’s obvious that some calling cards companies use it as a way to profit.
• Hang-up Fee: When the remaining balance of a calling cards gets to less than the amount required for a one-minute phone call, this fee may apply to reduce the balance to zero. Then the calling cards will be purged from the system soon.
• Service Fee: Some phone cards that look pretty cheap can turn out to be not cheap at all. Certain calling cards are advertised with an attractive total minutes in the card. But that number was calculated based on a single call per card. Certain phone cards charge a Service  fee up to 25% of the phone call’s cost. This makes the rates to be 25% more expensive in reality. The advertised total minutes looks more attractive because this fee is usually applied after the call is finished. Long Talking Fee: Certain calling cards charge this fee that’s rarely known to lots of customers. If the customer talked for more than 20 mins, 40 cents will be charged for every 20 minutes talking time. This equals to 2 cents more per minute.
