Our experience has been mixed. We were able to tap in to a wireless net at a marina in Nassau
- it wasn't the finest connection in the world, but it was acceptable.
(such as Cat Cay) didn't have one available.
We recently got an 'air card' from ATT. ATT is good because they use the same cellphone signal type (GSM) as they use in the Bahamas
. Unfortunately, we weren't able to use and test it out on our last trip. A possible 'down check' on using an aircard is that you'll end up paying roaming charges as it's being carried on a cellphone signal.
Anyway, that's our experiences. If anyone has better ideas, we'd love to hear them!
