Smart phones generally have a dedicated GPS receiver (with support for several satellite constellations). A smart phone dependent on the network for positioning would be an exception at this point (they certainly use the network to speed up location acquisition and improve precision, but they are not dependent on it).

But what can happen while traveling into new areas is that whej data link drops the mapping ap blanks, rendering the gps fix less than useful and giving the impression that the device is dependant on data coverage. Most phones have a facility to pre-download maps to cover this situation but you need to know to do it.

GPS receivers without maps are still perfectly useful if you have appropriate paper maps. And even if you have a dedicated GPS receiver with maps you need to pre-download maps as well.
