My wife and I just left Puerto Rico in Jan 2019. My Jetpack DID NOT work! I contacted support and they said it would not work in Puerto Rico. We ended having to purchase a mobile hotspot device from Clario in Pureto Rico. It work, but coverage was very limited. When we went to Cuamo and Ponce, the Clario device did not work. But I can definately say the JetPack did not work either.
