Looking for opinion on mobile coverage by main providers. I always thought Spark had the best mobile coverage outside the main centers. But a quick look at some of the coverage maps finds a few locations where Spark has no service(or minimal reception). Like State highway 1 on desert road, East Cape area. Also places like Kawau Island. Does the extra 1.5% make a difference to people who travel around NZ to work? Do people who travel carry both networks phones now?
