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.

The phone cannot be switched on
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.

Gray menu options
Gray text indicates a function is temporarily unavailable. 
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, picture 
or sound.

Insert SIM.
There is no SIM card in the phone or you may have 
inserted it incorrectly. See “SIM card and battery 
information” on page 4.

Insert correct SIM card.
The phone is set to work only with operator-specific 
SIM cards. Insert the correct SIM card.

Emergency only
You are within range of a network, but you are not 
allowed to use it. However, in an emergency, some 
operators allow you to call an emergency number. 
See “Emergency calls” on page 24.

No network. (or no operator name displayed)
There is no network within range or the received signal 
is too weak. You have to move to get a signal that is 
strong enough.
