Positioning methods

Your phone shows your location on the map using GPS, GLONASS, A-GPS, Wi-Fi, or network (Cell ID)

based positioning.
The availability, accuracy and completeness of the location info depend on, for example, your

location, surroundings, and third party sources, and may be limited. Location info may not be

available, for example, inside buildings or underground. For privacy info related to positioning

methods, see the Nokia Privacy Policy.
The Assisted GPS (A-GPS) network service and other similar enhancements to GPS and Glonass

retrieve location info using the cellular network, and assists in calculating your current location.
A-GPS and other enhancements to GPS and GLONASS may require transferring small amounts of data

over the cellular network. If you want to avoid data costs, for example when traveling, you can switch

the mobile data connection off in your phone settings.
Wi-Fi positioning improves positioning accuracy when satellite signals are not available, especially

when you are indoors or between tall buildings. If you're in a place where the use of Wi-Fi is restricted,

you can switch Wi-Fi off in your phone settings.
The trip meter may not be accurate, depending on the availability and quality of your satellite
