I’m not 100% sure that it was in Turkey because my phone was in airplane mode.
GPS actually doesn’t have to rely on a wifi connection, and you can use it in Airplane mode because it doesnt transmit anything. If you have a window seat you can often get a GPS fix just with signals through the window. It can help if you have an app on your phone that shows you what GPS satellites you can see, it will tell you when you have a good fix.
Then, just open your maps app of choice, and it should still know where you are. You won’t get a detailed map without an internet connection, but if you zoom out enough you should be able to see what part of the world you are in.
For some reason, this has never worked for me
Some map apps dynamically download the map for where you are so it would be blank in airplane mode unless it’s preloaded
It should be flying too, if it was over it, no ?
