Get Google Maps
This is especially true when traveling abroad. Many map applications won’t label or show all of the little streets, alleys and other roads in every foreign country but Google Maps does better than most. It certainly does better than Apple Maps in many situations.
If you haven’t downloaded Google Maps yet, now is the time. You may also want to check up on the cities you are traveling to so you can compare your map apps to see which will work best for your trip.
