The phone does not switch on
Remove/reinstall the battery. Then charge the
phone until the battery icon stops scrolling. Unplug
the charger and try to switch the mobile on.
The display shows BLOCKED when you
switch on the phone
Somebody tried to use your phone but didn’t know
the PIN code nor the unblocking code (PUK).
Contact your service provider.
The display shows IMSI failure
This problem is related to your subscription.
Contact your operator.
Your phone doesn’t return to idle screen
Long press the hang-up key or switch off the phone,
check that the SIM card and the battery are
installed correctly and switch it on again.
The network symbol is not displayed
The network connection is lost. Either you are in a
radio shadow (in a tunnel or between tall buildings) or
you are outside the network coverage area. Try from
another place, try to reconnect to the network
(especially when abroad), check that the antenna is in
place if your mobile has an external antenna, or
contact your network operator for assistance/
information.
The display doesn’t respond (or the
display responds slowly) to key presses
The display responds more slowly at very low
temperatures. This is normal and does not affect
the operation of the phone. Take the phone to a
warmer place and try again. In other cases please
contact your phone supplier.
Your battery seems to over heat
You might be using a charger that was not intended
for use with your phone. Make sure you always use
the Philips authentic accessory shipped with your
phone.
Your phone doesn’t display the phone
numbers of incoming calls
This feature is network and subscription
dependent. If the network doesn’t send the caller’s
number, the phone will display Call 1 or Withheld
instead. Contact your operator for detailed
information on this subject.
