Change phonecode

You define and enter the phone code (4-8 digits) when calling up a phone code protected function (e.g. Babysitter, p. 17) for the first time. It is then valid for all functions. If you have forgotten it, please call Siemens Service (p. 85).

Clear SIM card barring

If the PIN is entered incorrectly three times, the SIM card is barred. Enter the PUK (MASTER PIN) provided by your service provider together with the SIM card according to instruc- tions. If PUK (MASTER PIN) has been lost, please contact your service pro- vider.
