Not sure about cellular-wifi connectivity in Orient Village. We are in Oyster Pond and right now very bad to non-exsistent. The unlocked HUAWEI LTE device for mobile wifi that a friend lent me did not do any better with the new simm card, and maybe worse, than the HUAWEI ORANGE unit that was in the unit as "plan B". Fortunately, the cable guy showed up Sat. and got us back on regular internet.
Anyhow, as to the LTE device, the guy at the Orange store sent me off to Dauphin in Marigot. Outlet is immediately on the inland side of the Mall a short walk, close to the vendor market. 1.5 gig card was 29.9 euro. May at some point load mobile device and the Ipad into the car and drive around the island to see what reception is like.
