1. Consider getting a billed calling card that you do not have to prepay.
   
   
2. Ask about guarantees.
   
   
3. Check rates carefully aside from the ones being advertised. Pay special attention on extra connection surcharges like call completion rules, USF fees, time restrictions, and distance restrictions.
   
   
4. Check other surcharges. Many pre-paid cards charge a first minute penalty, minimum call lengths, large payphone fees, monthly service fee, a recharging fee, or set expiration dates which you have to pay to extend to save unused time.
   
   
5. Check the customer service number for the provider and verify that it works before purchasing the card.
   
   
6. Make sure the card has the full time promised by verifying that it comes in a sealed package and that the PIN is not visible.
   
   
7. Ask who the underlying provider is to know which company will be carrying your calls.
   
   
8. Be careful of prepaid card providers that won't answer your basic questions in a professional manner.
   
   
9. Ask trusted sources (friends, family, lawyers) if they have a card to recommend.
