You can always use GPS on your mobile device regardless of an internet or cellular connection. As long as you have a charged smartphone with you, you can find your way around remote areas and foreign landscapes. GPS tracking on your phone works just as well without internet connectivity or cellular service.

This is a question that comes up often and contrary to what one might think, GPS usage does not require much data. … Thus, if you want to use GPS for a long road trip of 2-3 weeks, you will need less than 200MB of data and 1000MB is approximately equal to 1GB.
