Unlocked Aircard for the caribbean/South America

[Meck]

Hello all,

I've got a question for the Caribbean Cruisers out there..

I was thinking about getting an unlocked aircard for the laptop and using it on our cruise along the coast of Central and South America.

My understanding is that as we stop in certain countries we could by a sim card with minutes and use the sim card in the unlocked aircard, thus giving us access to the Internet.

Is anyone using this method to help stay connected?

Thanks for any and all insight.

Jon
