yeap,
tat Plaza`at Fruisa is named Plaza Larimar,
you can not miss the porange shop there, entre the parking place and on the right side middle of the small plaza grongfloor it is, big Ornage signs on. like written above $10.- per sim with 200 pesos credit on, it is located right on the way from the airport to the iberostar, 7-8 minutes before you rach the resort. you know when there when you see the Texaco gas station, plaza larimar is right across the street.
have fun
