OK, so now I feel like a ludite. I have google maps on my android phone, but I wasn't aware that my phone had a gps in it. How do I find the gps on an android phone?Regarding using phone maps while travelling - download Google Maps, if you don't already have it. When you're on a wifi connection, you can actually download maps of areas that you specify so that you can use them even without a data connection. The only requirement is that you have a good GPS connection (which is built into the phone and doesn't cost money to use). I do this when I go out of the country. Worked great for when I went to Vegas and Hawaii.
You can save an area from Google Maps to your phone or tablet and use it when you're offline. Tip: You’re unable to download offline maps in some countries or regsupport.google.com
As far as I know, google maps uses mobile data.
