Security and data management
Manage the data and software on your device, and take care
of the security of the device and its contents.
Important: Your device can only support one antivirus
application. Having more than one application with antivirus
functionality could affect performance and operation or
cause the device to stop functioning.
Lock the device
Important: If the device has been locked, enter the
lock code to activate the phone function. When the device is
locked, calls may be possible to the official emergency
number. Making an emergency call in the offline profile or
when the device is locked requires that the device recognise
the number to be an official emergency number. It is
advisable to change the profile or unlock the device by
entering the lock code before you make the emergency call.
To prevent access to the contents of your device, lock the
device in the standby mode. Press the power key, select Lock
phone, and enter your lock code. The default lock code is
12345. To unlock, press the left selection key, enter your lock
code, and press the scroll key.
To change the lock code, select Menu > Tools > Settings >
General > Security > Phone and SIM card > Lock code.
Enter the old code and then the new code twice. The new
code can be 4-255 characters long. Both alphabets and digits
can be used, and both uppercase and lowercase alphabets
are possible.
You can also lock the device remotely by sending a text
message to the device. To enable remote locking and to
define the text for the message, select Menu > Tools >
Settings > General > Security > Phone and SIM card >
Allow remote lock > Yes. Enter the remote lock message
and confirm the message. The message must be at least 5
characters long.
Tip: Remote locking also locks your memory card. To
unlock the memory card, select Menu > Tools >
Memory > Options > Remove password, and enter
the remote locking message as the password. If the
message is longer than 8 characters, the first 8
characters are used as the memory card password.
