I used Lime in November. Got a deal on the phone, $999j including SIM and $100j in minutes. VERY cheap. I didn't have any problems at all calling home or locally and texting.

I know Marko has used Lime as well and didn't report any problems. I think Lime is cheaper because it's working to overcome Digicel's majority of the market. Locals and tourists have been using Digicel for awhile, thus, it is favoured, but I really didn't find anything wrong with Lime and for my purposes, why not go with something that is a quarter (in my case) or half the cost?
