Not true. Using google maps i made sure that before I left toronto I had the last page of google maps on mexico and guatemala. I constantly was able to get a gps location. No cell phone service in Guatemala I just used the map that stays on the phones memory....could not zoom in to update phone but I was able to see exactly where i was all the time....without ever having cell phone service. So before you leave make sure u go into google maps and leave it on a position you are ok with to see ur position...once in London start up google maps and us gps...map will not update but gps will work.
