And all of this is true, but I can very personally advise great caution here. Your Android phone may have the maps, but many do not actually have GPS. They rely on "Carrier Locations Service" which simply means that the current tower tells the phone where it is with the same system of range and bearing that it uses to decide which cell to hand you off to when needed. If you don't have a tower in range, you are just SOL. (Second On Line)
I discovered this when my good phone took a hit and we needed a replacement on the road. The replacement selected for low price suddenly went out and could not do anything to get us a location. Fortunately, it was not the only GPS on board.
Lesson Learned at small cost.
