Mike-

I was charged the CBW Liechtenstein mobile rate of .56/minute plus the UM incoming call rate for Costa Rica of .30/minute. That's slightly less than if I had used the UM outgoing rate for Costa Rica of $1.15/minute, but obviously wouldn't want to do a lot of yacking at either rate! ;)

yackie sim
 

Hi,

This form has been mostly helpful, I'm traveling to Costa Rica tomorrow and based on info found here I bought a yackie sim, Celtrek has cheaper call rates and no free incoming, but on initial purchase Yackie was less expensive, because Celtrek does charge for the sim..

On second thought though I should have gone with CelTrek as call rates are less expensive than Yackie plus callback to yackie's free incoming is hardly an option because rates to Iceland mobile are quite high so I'll just have to use the yackie sim as is. I wish local calls within Costa Rica was cheaper.

Anyway, too late now, I will let you guys now how it works out.

edit: just checked and rates in neighboring countries such as Panama, el Salvador, is a lot cheaper with yackie.

If you have a chance to ask about plans for prepaid in the future, please report back what you learn.
