Digicel used to sell a portable wifi device made by Alcatel. It had a phone chip in it but you couldn't use it as a phone, just wifi. It worked ok but here's the thing, you still need a cell signal to use this Alcatel so why not just bring a good smart phone down with you, buy a Digicel chip and use phone data. Data is cheep and now you have a phone and data. If you need to use a tablet just use the hot spot on your phone. 7 day 40GB plan is $1,500J according to the Digicel web site.
