How to

Turning use of PIN on or off

If you want to protect your SIM against unauthorised use, you need to turn on use of PIN. Once done, it needs to be keyed in every time you use your modem.

Click Tools.

Click PIN Operations.

Click Enable PIN Verification... or Disable PIN Verification... (depending on the current setting).

If an incorrect PIN is entered three times in a row, your SIM will be blocked. To unblock your SIM, you'll need to key in your PUK. The PUK can be obtained by contacting Customer Service.
Please note:
If an incorrect PUK is entered ten times in a row, your SIM is blocked permanently. In this case, you'll need a new SIM from Optus.

Key in the PIN and click OK.

Click OK.
