first of all mi discourage bringing anything expensive to Jamaica......especially phones......
you always better off using a cheapy bought or brought here so you don't loose sumthin expensive in paradise......

Digicel sim is about $600J's and Lime is about $300J's......
neither Digicel or Lime will cut down a sim down to micro or nano size.....
but you can go upstairs from the Digicel Store is and a guy cuts dem for $600J's......
Lime has a 3 day data plan for $50J's.....and Digicel wants $60J's per day....
good enuff to do a likkle internet stuff like Facebook, emails and whatsapp etc......
they both have better and more expensive dat packages.....
you just enter codes/numbers into your phone to get the plan you want...

I will cut down a regular size sim down to micro size for free......mi hang at Pee Wees
