Hi there.   We are going away on a camping trip to Motutapu island.   I'm really hoping to get decent cellphone reception. Using XT obviously. We will be staying on the old WWII site in Administration Bay.

Already searched for Cell Towers nearby, and there's none on the island, (Obviously), so my main question, should we still get reception, possibly by the mainland transmitters overspilling, over the island? Or is there zero hope at all for reception?   Thanks
