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 6.

No indication of charging
When you start charging a battery that is empty or a 
battery that has not been used for a long time, it may 
take up to 30 minutes before the battery icon appears in 
the display.

Menu language
If the display shows a language that you do not 
understand, you can always set the following 
from standby:

• Press 

 0000 

 for English menus.

• Press 

 8888 

 for automatic, local menus.

Note: Themes are also set to factory default.

Grey menu options
Grey text indicates a function that is 
temporarily unavailable, for example, due to 
your subscription or due to a certain setting 
which has not been turned on.

Since you cannot send themes, pictures and sounds 

that are copyright-protected, the Send menu is 
sometimes unavailable.

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 6.

SOS calls 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 the international emergency 
number 112. See “Emergency calls” on page 33.
