Voice call barring
Select the desired barring option and Activate, Deactivate,
or Check status. Call barring affects all calls, including data
calls.
Q: Why do missing, discoloured, or bright dots
appear on the screen every time I switch on my
device?
A: This is a characteristic of this type of display. Some displays
may contain pixels or dots that remain on or off. This is
normal, not a fault.
Q: Why can't my Nokia device establish a GPS
connection?
A: Establishing a GPS connection may take from a couple of
seconds to several minutes. Establishing a GPS connection in
a vehicle may take longer. If you are indoors, go outdoors to
receive a better signal. If you are outdoors, move to a more
open space. Ensure that your hand does not cover the GPS
antenna of your device. If the weather conditions are bad,
the signal strength may be affected. Some vehicles have
tinted (athermic) windows, which may block the satellite
signals.
Q: Why can't I find my friend's device while using
Bluetooth connectivity?
A: Check that both devices are compatible, have activated
Bluetooth connectivity, and are not in hidden mode. Check
