PIN2 code
PIN2 is the abbreviation for Personal
Identification Number 2, and is used
to restrict use by unauthorised users
as with the PIN.
The PIN2 code change procedure is
the same as the one for the PIN
code. 3 incorrect PIN2 code entries
would invalidate the PIN2 code.
In this case, you have to enter the
PUK2 code in order to use the PIN2
code again. The maximum number of
times you may try to enter the PUK2
code is 10, like PUK1. 10 incorrect
PUK2 code entries would invalidate
the PIN2 code.
Security code
The security code is used to change
the mobile phone password. The
maximum number of attempts to
enter the security code is not limited
as it is with PIN2.
Flight mode
If you acivate the Flight mode, you
can use the phone without
connecting the 2G wireless network.
2G wireless phone and FM radio
signals from the phone or Bluetooth
connections are prevented, but you
can still do tasks which do not
require the use of wireless network.
With flight mode you cannot make
any calls including emergency calls
or use other features that require
network service.
