A-GPS could help the phone to connect to the satellite faster. However, A-GPS requires the internet connection. Therefore, if you are not subscribed to the unlimited data plan package, you may want to disable the A-GPS support.
My ignorance of this issue had cost me a few hundreds Ringgit.
To disable the A-GPS support in Nokia 5800, follow this steps:
- Press the white Menu button.
- Select Apps.
- Select Location.
- SelectPositioning.
- Select Positioning Methods.
- Select Assisted GPS, and select Disable.
