      If the wrong PIN is entered three times in a row, your SIM is 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 the wrong PUK is entered ten times in a row, your SIM will be blocked permanently. In this case, you need a new SIM from Telstra.
