Nokia 2720 - Manual (Page 18)

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.
If your device displays a message that the memory is full,
delete some of the information stored in the shared
memory.
Access codes
The security code helps to protect your phone against
unauthorised use. The preset code is 12345. 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 unauthorised 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.
