Glad to see it works in Roatan. To those that are using Skype in Roatan, do you use the "pay as you go" or monthly plan? Is there a minimum number of months you have to sign up and pay for? I believe the rate to call landlines in the US is fairly high in Honduras compared to other countries if you use the "pay as you go". Skype's global calling plan appears to be the way to go. Correct me if I'm wrong.
Don't buy a plan if you don't expect to use skype calling more than this trip. Buy like $10 in credit, and that will last you a LONG time (around 200 minutes). It's only around 2 cents a minute to call US phones from wherever you are.
The other cell phone options are good, but more costly. Now, I have a Claro Blackberry with a plan, since I live here more of the time. I used to use an unlocked quad band phone (bought on Ebay for $10) and bought a Local SIM for a few hundred pesos (about $10 dollars). Here in the D.R. - incoming calls are free - so skype forwarding works like a charm. I guess it depends on how connected you need to be. Outgoing calls to the U.S. on my Orange SIM service were about 25 cents a minute. Considerably less than the $1.00 a minute from AT&T or Verizon.
When people I know are coming here... I recommend they use Skype. We all (our little group of gringo residents here) use Skype in a similar fashion to how I've outlined.
