This chapter lists some problems that you might
encounter while using your phone. Some problems
require that you call your service provider, but most
of the problems you can easily correct yourself.

Recharge or replace the battery.
See “SIM card and battery information” on page 4.
No indication of charging
When charging a fully-discharged battery, it may take
up to 30 minutes before the battery icon appears in
the display.

This may be because the service is not included in your
phone service subscription, or because a certain phone
setting has not been turned on, or is otherwise not
selectable. For example, the Send menu may be displayed
in gray if you selected a copyright-protected theme, pictur

or sound.
