get a GSM phone with wifi hotspot and you can use your laptop to connect to the internet via the wifi hotspot phone...
when you sign up for either Digicel or Lime data packages........
as long as you have enuff credit you just type in some codes to get the data plan with either carrier.....
it's the cheapest route to go when you can't get a wifi signal where you are at........
and both carriers have a half decent selection of data plans too.........
between picking up wifi signals when you are out at different establishments and then using your wifi hotspot cellie when you can't......you should always be able to get on the internet in paradise..........
