Using the Modem Manager
Manual Revision

Entering a PUK
If you have forgotten your PIN or have entered an incorrect PIN three or more times, you are
required to enter a PUK (PIN Unblocking Key), in order to unblock your SIM card. See Figure 31.
Figure 31 Enter PUK and PIN dialog box
Your service provider will give you the
PUK
and a new
PIN
. Carefully enter these values into their
respective fields, and click
OK
to save the values. Once the values have been accepted, the SIM
card will no longer be blocked and the PIN will be changed. The Modem Manager will now be
able to access your network account information.
Note:
If you enter a PUK incorrectly three times, the SIM card will again be blocked. You must con-
tact your service provider to obtain a new PUK and PIN.
