In order to save the high roaming fees as a tourist and vacationer, you should opt for cheap prepaid offers and call e.g. via Skype with families and friends.
The best known companies in the country for telecommunications are Movistar (Telefonica Company = O2), Claro, Digicel and +Movil.
To top up the prepaid offers there are orange machines e.g. at the airport or the bus terminals. Furthermore, you can buy small scratch cards for 2, 5 or 10 dollars at many shopping malls. At Movistar you often get a fivefold increase of the amount and several free minutes in the same network, as well as good offers for mobile internet.
