protected functions.

Following the third unsuccessful

attempt, access to the phone code

denied. If this occurs, contact the

Siemens Service (p. 58).

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 with the SIM

card in accordance with the instruc-

tions. If the PUK (MASTER PIN) has

been lost, please contact your serv-

ice provider.

elling in an aircraft.
