SIM-LOCK-free:
This phone is SIM-LOCK-FREE.
This means the phone is not bound to SIM
cards of a certain provider, allowing you to
choose any desired telephone company.
PIN code / PUK code:
Each SIM can be secured using a PIN.
This PIN code helps you to prevent unau-
thorised persons from using your phone.
In most cases, the documentation accom-
panying the SIM card will show a PIN set
by default. You can change this PIN your-
self.
After you’ve entered an incorrect PIN for
up to three times, the SIM card will be
locked. You then need the PUK code of
the SIM card to unlock the card again.
Also the PUK code is usually mentioned in
the documentation your supplier provided
with the SIM card. If this information is not
available, please contact the help desk of
your supplier.
