Cell phone tips???

[drjudy]

Hi gang,
I'm planning my mini-retirement for January - March 2008 to go to Costa Rica, maybe Argentina. My main focus will be to learn Spanish, and whatever other fun adventures I can find.

One of my big concerns is about using cell phones in South American countries. Does anyone have any experience in using them over there? I have 3 grown children and a 72 year old mom I have to stay in touch with - I'm sure everyone understands!

I've heard of world phones, changing SIM cards to local chips, and forwarding messages from VOIP. But I'd like the reassurance of being able to pick up a phone and getting a hold of family without it costing $3/minute!

Any suggestions would be appreciated!
