Unlocking The Sim Card - Denver SDQ-52004L User Manual

2.4.3 Unlocking the SIM card

The PIN 1 (personal identification number)
secures your SIM card from being misused by
others. If you have selected this function, you
must enter the PIN1 code each time you turn on
the phone so that you may unlock the SIM card
and then make or answer calls. You can
deactivate SIM card protection (see "Safety
settings"). In this case, the misuse of your SIM
card cannot be prevented.
 Press the Hang Up key to turn on your
phone;
 Enter your PIN1 code. Clear the incorrect
digits by using the right soft key, and press
OK for confirmation. e.g. if your PIN1 is
1234, please enter:
1 2 3 4
If you enter incorrect numbers for three times
in succession, your SIM card will be locked and
your phone will ask you to enter PUK 1 number. If
you do not know the PUK1 code, do not try.
Instead, contact your network service provider.
See "Safety settings".
Note: your network service provider sets a
standard PIN1 code (4 to 8 digits) for your SIM
