One of the greatest accomplishments of corporate misinformation has been the cell companies' success at making people think that you need cell service to have have GPS. *

While out of cell or wifi range, you should be sure to use a chartplotter program that caches the charts locally. Most of them do that, but some of the freebies do not.


* Another similar piece of misinformation is that you need a "High Definition" cable plan to receive local broadcast channels in Hi Def. In virtually all metropolitan areas, all you need is an ordinary old-fashioned antenna. All the local channels are REQUIRED to broadcast in high definition.
