During device setup, Location Services is skipped on your iPhone.

If Location Services was skipped during iPhone setup, it must be enabled before Maps can use the device’s location for navigation. Go to Settings > Privacy & Security > Location Services and turn Location Services on. Maps must then be granted appropriate location permission. For precise turn-by-turn directions, Precise Location should also remain enabled for Maps. Apple explains that Location Services uses available GPS, Wi-Fi, Bluetooth, and cellular information to determine the device’s approximate or precise position. Background location access alone cannot solve the problem if Location Services itself is disabled. An MDM administrator is not normally required to activate the user-controlled setting, and simultaneous Wi-Fi and cellular connectivity is not mandatory for location determination. Therefore, option C is correct.
