• 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. Your
phone does not support 5-Volt SIM cards and the card may need to be
changed.
TIPS ON EFFICIENT OPERATION: Your phone has a built-in
antenna. As with any other radio transmitting device, do
not touch the antenna unnecessarily when the phone is
switched on. Contact with the antenna affects call quality
and may cause the phone to operate at a higher power
level than otherwise needed. Not touching the antenna
area during a phone call optimises the antenna
performance and the talktime of your phone.
