Are you fed up with paying too much for long-distance calls while traveling? Consumer Action's Linda Sherry says most pre-paid phone cards will save you money but the surcharges can add up. Use the card at a pay phone and you'll be charged an additional 24 to 75 cents.
Use the card to call a mobile phone and sometimes a different rate structure kicks in. Weekly and monthly maintenance fees are common. All these charges can eat up your minutes fast. Fees must be on the card itself or packaging, according to California law. The best deal I've found is the card sold at Costco.
