The phone card mentioned by Deb (Apple & Orange) are also distributed by Goldline (Ola, CiCi, Travel, etc, etc). Some of the phone cards charge by minute increments while others on 3 min ones. Ask at the place you buy your cards from. They should be able to tell you the differences. Most of the phone cards will note the fact that calls to overseas cellular phones are more expensive. Not sure why...most probably the type of networks used...landlines as supposed to satellites, etc. I find some of the phone cards issued by Millenium to be very reasonable. The Nuestro Mundo gives you 451 minutes to the DR on a $20 card. Connection fee: $1.99
