I'm pretty sure there is just one carrier in Costa Rica, and it's controlled by the government. And it's pretty easy to get a SIM card, so unlock your iPhone and use there rates
 
How about an iPad?

From what I've been reading, I may-or may not-be able to buy a prepaid SIM card to use in my iPad while I'm in Costa Rica. I'll be on a sailboat, so WiFi isn't an option. Some posts indicate only CR residents are able to do so; others say anyone can do so. Advice anyone? Thanks!
