How does your iPhone maps app track you even though you do not have an Internet carrier only wi-fi?

The iphone Maps app can track your location using GPS signals, which operate independently of your cellular carrier. Even without a mobile data connection, the app can access Wi-Fi networks and use their signals to triangulate your position more precisely. Additionally, if your device has previously connected to known Wi-Fi networks, the Maps app can leverage that data for location accuracy. This allows for effective location tracking as long as Wi-Fi is available.
