GPS
About positioning methods
Your phone displays your location using GPS, A-GPS, Wi-Fi, or cellular positioning.
The Global Positioning System (GPS) is a satellite-based navigation system used for
calculating your location. Assisted GPS (A-GPS) is a network service that sends you GPS
data, improving the speed of the positioning. In addition, other enhancements to GPS
may be used to improve and speed up the positioning. These may require transferring
small amounts of data over the cellular network.
Wi-Fi positioning improves position accuracy when GPS signals are not available,
especially when you are indoors or between tall buildings.
With cellular positioning, the position is determined through the cellular network
antenna your phone is currently connected to.
To save on data costs, you can deactivate A-GPS in your phone positioning settings, but
calculating your location may take much longer.
You can deactivate Wi-Fi in your phone internet connection settings
Depending on the available positioning methods, the accuracy of positioning may vary
from a few metres to several kilometres.
Deactivate assisted GPS (A-GPS)
Assisted GPS (A-GPS) helps your phone determine your current location more quickly. A-
GPS is a network service. To save on data costs, especially when abroad, you can
deactivate the service.
Select
and Device > GPS and positioning, and deactivate Mobile data
connection.
The Assisted GPS (A-GPS) network service retrieves location information using the
cellular network, and assists GPS in calculating your current location.
Your phone is preconfigured to use the Nokia A-GPS service, if no service provider-
specific A-GPS settings are available. The assistance data is retrieved from the Nokia A-
GPS service server only when needed.
You must have a mobile data internet access point defined in the phone to retrieve
assistance data.
Note: The use of assisted positioning methods may involve exchanging your
location data, wireless network identifiers along with your unique phone or network
