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 when in home screen. 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.
