Java applications are automatically installed as
“Trusted” or “Untrusted”. Trusted applications are
allowed to, for example, connect to networks, send
messages or use the camera without asking for
permission. Untrusted applications, however, must
always confirm such actions with you first. You
can set different permission levels for your Java
applications.

permission level you want for the application.
Java application screen size
Some Java applications are designed for a specific
screen size. In some cases, applications may not
be able to start because the phone cannot adapt the
application to the screen. Contact the application
vendor to find out what screen size the application
is designed for, and change the screen settings for
the application in the phone.

SIM card lock
The SIM card lock protects your subscription, but
not your phone itself, from unauthorized use. If you
change SIM cards, your phone still works with the
new SIM card.
Most SIM cards are locked at the time of purchase.
If the SIM card lock is on, you have to enter a PIN
(Personal Identity Number) every time you turn on
your phone.
