I am interested as well and probably many others. I used Digicell's email support
bvicustomercare@digicelgroup.com to ask what frequencies they were using for 3G (like others they call it 4G now but it is really a marketing term - I call it faster 3G). A "Special Project Manager" wrote back the next day. It wasn't a perfect answer, she only told me one frequency but with some friendly additional questioning I got my answer. So far I haven't found Lime's email support so I called - that went nowhere quick...
The only thing I've seen about hotspotting an Iphone on Lime is that mrsimcard.com says they don't support it. I doubt they would have gone out of their way to say that if it wasn't true. I can say that any carrier can prevent it if they want to - att won't let you unless you pay them $20 extra per month to use you data that way and the att mvno's just leave the "Personal Hotspot" greyed out.
I just bought two unlocked wifi hotspots that I will be testing on our next trip and then my least favorite will go to my brother-in-law in Greece. The other I plan to use enough times that it pays for itself. At $17 a day it will only take one trip.
I think it was RickG that may have come up with the best solution. He went to a Digicel store, got their wifi device and added a data plan. That's a low stress way to do it and for a little extra price for the device they set it up and make it work! For me I wanted one that would work on att's 4G when in PR/STT and one to send to Europe, that also worked in the BVIs, so I had a lot more work to do.
If Digicel or Lime allows tethering an iphone that should be very popular among TTOLer's! If all of the charter companies supplied this for free or at least cheap all the better.
