This does require you to pre download the maps for the area you will be in so they are available offline. Otherwise you do not need cell coverage to track yourself via the GPS in your phone.

Have you used this for the application I intend to use it for? Is the gps on the phone reliable in remote areas? Does it use one satellite, or more, does cloud cover affect it, etc?
