If you don't mind me asking, what device does your daughter have? I have the Samsung Galaxy S4 and I was just there in Puerto Rico visiting my family and I had no 4G / no LTE service at all. I couldn't even get 3G to work on my phone or on my hot spot Jet Pack that Verizon swore would work there. Do you have to do anything to the settings on the phone to make it work in Puerto Rico? Anything I would have to do on the Jet Pack MiFi?
