My A.T.&T. cell phone works fine there. But before your trip, you've got to call your cell phone provider and have them turn on the international roaming feature to your phone. If memory serves, it's an additional $3.99 per month for this feature. Once you've done this, simply turn on your phone when you're in CR, and it'll search for a signal. Then it'll dial in to the ISC network, and you're ready to make a call. But beware, as it's around $6 or $7 per minute for phone calls. There are much cheaper options out there, but this will work in a pinch. Do a search on the forum and you'll see a bunch of different alternatives.
Pura Vida,
