Connectivity security
Nokia understands how important it is that your mobile phone or device operates
reliably and that your personal content is saved safely.
Any information from an unknown or unreliable source, for example, via Bluetooth
connectivity, multimedia message, or cable, may harm your PC, mobile phone, or device.
You may protect your mobile phone or device from damage and keep it secured by
following simple measures:
• Always keep Bluetooth connectivity closed unless you want your phone or device
to be visible to others, when your phone or device supports Bluetooth.
• Always be alert when receiving information, like Bluetooth file or multimedia
message, from an unknown or untrustworthy source.
• Do not download or install any applications that may include software harmful to
your phone or device.
• Always download and install applications or content, like ringing tone or game,
from trusted or well-known sources, such as Nokia Store, where good protection is
provided against viruses and other harmful software.
This is a friendly reminder, the mentioned function may vary from different device
model.
