Philips Xenium x331 User Manual page 24

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.
You can't send text messages
Some networks don't allow message exchanges with other networks. First check that you have
entered the number of your SMS centre, or contact your operator for detailed information on this
subject.
You can't receive and/or store JPEG pictures
A picture may not be accepted by your mobile phone if it is too large, if its name is too long, or if it
doesn't have the correct file format.
You feel that you have missed some calls
Check your call divert options.
When charging, the battery icon shows no bar and the outline is flashing
Only charge the battery in an environment where the temperature does not go below 0°C (32°F) or
above 50°C (113°F).
In other cases please contact your phone supplier.
The display shows SIM failure
Check that the SIM card has been inserted correctly. If the problem persists, your SIM card may be
damaged. Contact your operator.
When attempting to use a feature in the menu, the display shows NOT ALLOWED
Some features are network dependent. They are only available, therefore, if the network or your
subscription supports them. Contact your operator for detailed information on this subject.
The display shows INSERT YOUR SIM CARD
Check that the SIM card has been inserted correctly. If the problem persists, your SIM card may be
damaged. Contact your operator.
The autonomy of your phone seems lower than indicated on the user guide
The autonomy is linked to your settings (e.g., ringer volume, backlight duration) and the features you
use. To increase the autonomy, and whenever possible, you must deactivate features you do not use.
