Skype is a good choice if you only want to use it while your on your computer. I have the WIFI Skype that is suppose to work
with out the computer but have found that 80% or more of the WIFI sites have a proxy page you have to pass through that the stand alone WIFI Skype phone
(like a cell phone) can not handle.
And since Skype can only work when you have WIFI you are out of luck when your out of range. Availability of WIFI isn't exactly everywhere.... it is only near or in Marinas
, towns, major cruising locations, and some beach side establishments but rarely in most of the better more isolated anchorages
or while your underway. If your going to be a marina barnacle then it is OK but very hit and miss if you actually do much cruising around.
You best option may be to get a Cell Phone
, the Pre-Paid that is unlocked and where you can get different SIM chips where you cruise
. Each island is often a different country and a universal phone
just does not exist yet. Good steps have been made in past couple of seasons but even with the same phone company, your roaming charges can be high just by location/ different country. A few overlap but for the lowest cost and widest range even where you have no WIFI, you will develop a set of SIM chips you change out as you move about the islands.
It is a very slow process but it is evident that some progress is being made where a single
phone can be used in a larger Geo area. At this time ATT appears to be the one that has the widest coverage areas but often at a high price
I would recommend you have a cell that will work in the area your sailing for emergencies and for making reservations and even clearing Customs
in some locations. Use Skype for the longer conversations when you reach a good WIFI source.
Again if your not actually cruising around, the Skype may be a good single
source but I like the back up of a Cell if only to get calls when they come in and not have the constant power drain of having the computer on all the time.
