■ Switching the phone on and off
To switch the phone on or off, press and hold the
power key.
If the phone displays Insert SIM card even though
the SIM card is properly inserted, or SIM card not
supported, contact your network operator or
service provider.
If the phone requests a PIN code or a security
code, open the fold, key in the code, and press OK.
See also Access codes on page 16.
Your device has an internal antenna.
Note: As with any other radio transmitting device, do not
touch the antenna unnecessarily when the device is
switched on. Contact with the antenna affects call quality
and may cause the device to operate at a higher power
level than otherwise needed. Avoiding contact with the
antenna area when operating the device optimises the
antenna performance and the battery life.
