Shared memory
The following features in this device may share memory:
multimedia messaging (MMS), e-mail application, instant
messaging. Use of one or more of these features may
reduce the memory available for the remaining features
sharing memory. Your device may display a message that
the memory is full when you try to use a shared memory
feature. In this case, delete some of the information or
entries stored in the shared memory features before
continuing.
Access codes
The security code helps to protect your phone against
unauthorized use. You can create and change the code, and
set the phone to request the code. Keep the code secret
and in a safe place separate from your phone. If you forget
the code and your phone is locked, your phone will require
service and additional charges may apply. For more
information, contact a Nokia Care point or your phone
dealer.
The PIN code supplied with the SIM card protects the card
against unauthorized use. The PIN2 code supplied with
some SIM cards is required to access certain services. If you
enter the PIN or PIN2 code incorrectly three times in
succession, you are asked for the PUK or PUK2 code. If you
do not have them, contact your service provider.
