Does the apple watch series 2 gps use data or roaming (when over seas)? I know it uses satellite but my maps on my phone caused me to have roaming charges last time i left the country.
I like to hike and take walks using gps on trips, especially those outside of the US.
Apple Watch Series 2, iOS 10, GPS
Hi
GPS itself does not use cellular / mobile data.
Apps that use maps, however (including the built-in Maps app), are a different matter.
You may find the following support article helpful, including for turning off cellular / mobile data and/or roaming if desired (I suggest doing this before departure, rather than on arrival):
