Chg. phonecode
You define and enter the phone
code (4-8 digits) when you call up a
phone-code protected function for
the first time. It is then valid for all
phone-code protected functions.
Following the third unsuccessful
attempt, access to the phone code
and the functions that use it is
denied. If this happens please
contact Siemens Service (p. 69).
Clear SIM card barring
If the PIN is
entered incorrectly three

provider, according to instructions. If
the PUK (MASTER PIN) has been lost,
please contact your service provider.
