I live in a remote area and travel to areas where typically only Telstra has had access in my experience.
Some of these places for example are Yuendumu, Kintore, Hermannsburg, Wallace Rockhole and some on the main drag like Erldunda, Marla Bore, to name butr a few.
The coverage map suggests these are all covered and all the other places I visit, but I've been fooled before by other providers in the past - so I'd like to confirm coverage before moving from Telstra ...
The coverage map is based on the parts of the Telstra 3G and 4G network which Boost uses, for the most part they have access to everything except for the 4GX speeds
AS far as I am aware, Boost is owned and operated by Telstra using all their towers, so I imagine covergae would be the same as Telstra.
