See how to turn on your mobile phone.

Turn on your mobile phone
Tap and hold On/Off until your mobile phone is turned on.
Enter PIN
If you're asked to key in your PIN, do so and tap OK. The default PIN is 0000.
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.
Turn off your mobile phone
Tap and hold On/Off until a pop-up menu is displayed.
Tap Power off.
