Wrong PIN
Analog phone or ISDN phone: If, instead of the busy tone or dialing tone, you
continue to hear 2 beeps - pause - 2 beeps - etc., it means the PIN was not
accepted. Check that you have the correct PIN and try again.
If a wrong PIN has been entered three times, you will hear 3 beeps - pause - 3
beeps - etc. This means you have to enter the PUK (PIN Unblocking Key)
provided with your SIM card.
After entering the PUK, you must enter a new PIN of your own choice (4 to 8
digits long).
Dial the following:
<PUK> * <New PIN> * <New PIN> followed by # or off-hook key.
Example: If the PUK is 87654321 and the new PIN is 1234, dial
87654321 * 1234 * 1234 followed by # or off-hook key.
If you enter 10 wrong PUKs, the SIM card will no longer be functional. Contact
your Airtime Provider for a new SIM card.
IP handset: After having entered the user name and password for the terminal
you have 3 attempts to enter the SIM PIN, before you are asked to enter the
PUK (Pin Unblocking Key). The PUK is supplied with the SIM card for your
terminal.
Enter the PUK followed by a new PIN of your own choice. The PIN must be
from 4 to 8 digits long.
If you enter a wrong PUK 10 times, the SIM card will no longer be functional,
and you have to contact your Airtime Provider for a new SIM card.
