A smartphone does not need cell service for the GPS to work. It has a dedicated GPS chip for this. A lot of the free or cheap apps need data to load maps but the higher end TomTom or Garmin apps have pre loaded maps that work just fine without cellular access. I use my 3G ipad with TomTom app that works much better than my Ford Nav or stand alone TomTom gaps unit.
