Denise,
Digicel does not offer a 3G service, they only have a 4G broadband network. Since the iPad2 is not 4G compatible, there would be no reason to contact Digicel since you wouldnt be able to use their service anyway. That leaves only LIME and Claro. The mrsimcard link above is the link to their offer for Claro's 3G network. It sounds as if that their offer will work, but at us$60 for 7 days of service, that seems a bit on the high side. The 7 day rate from Claro is not quite us$20. Sims cost about ja$700 - less than $10. So mrsimcard seems to making a nice 100% profit for providing their service.
The simcutter would be an option to cut the sim you would purchase from LIME or Claro to fit your iPad. Purchasing a sim from either LIME or Claro is a viable option. Since Apple designed your iPad2 to be both wifi or 3G enabled - this whole 3G issue can be avoided by simply using the free wifi available all over town. I have helped many of the businesses in Negril with their wifi systems.
A short list of places in Negril that offer free wifi are The Caves, Ivans, Seastar Inn, DeBar, Rockhouse, 3-Dives, Swordfish, Chicken Lavish, MiYard, Canoe, Winners, Travellers, Yellowbird, Cafe Goa, Wades Hot Spot, Italian Cafe, Sunrise Cafe, Aqua, Fun Holiday, Sun Beach, Margaritaville and Boardwalk. There are others, but this should give you a good idea of what is available for free by simply getting a drink at any of these establishments.
And by the way, I have lived in Negril for about 20 years now, and know the ins and outs to connectivity issues in Jamaica.
