Security
Your PIN (Personal Identity Number) code is
a code that you can use to protect your
phone from unwanted users. This is the
number that the phone may ask for at switch
on. The options are as follows (depending
on what PIN activation settings you have
selected):
Activate PIN
Enter your PIN at switch on (if your SIM
card supports this).
Deactivate PIN
You do not have to enter your PIN at
switch on.
Change PIN
Select this to change your PIN code.
Change PIN2
Some network services require a separate
security code - the PIN2 code. Select this
option to change your PIN2 code.
To activate, deactivate or change the PIN
code, you need to enter the current PIN
code. To change the PIN2 code, you need
to enter the current PIN2 code. If you don't
know your PIN code or PIN2 code, contact
your service provider.
If you enter the wrong PIN or PIN2 code
three times, the SIM card is locked and you
may be asked to enter a PUK (Personal
Unlock Key) code - these may be different
for PIN and PIN2. The PUK codes may be
listed in the information that you received
with your SIM card or they may only be
available from your service provider.
ζ
Note: Sendo cannot provide your PUK
codes. Contact your service provider for
information.
