Note: The use of GSM high-speed data services requires that your network
supports HSCSD (High Speed Circuit Switched Data) technology and that you
have subscribed to this service. GSM high-speed data services may cost more
than normal GSM data services. Contact your service provider for more
information.
Note: Since Bluetooth devices communicate using radio waves, your phone and
the other Bluetooth device do not need to be in line of sight. The two devices only
need to be within a maximum of 10 metres of each other, although the connection
can be subject to interference from obstructions such as walls or from other
electronic devices.
In some countries, there may be restrictions on using Bluetooth devices. Check
with your local authorities.
