Does your new Mobile need to be activated?
If you receive a SIM with your new phone it will auto-activate within 4 hours of delivery. Periodically turn your device off and on until your SIM has activated. You will see Optus next to the coverage bars once the SIM is active.
If you did not receive a new SIM with your delivery, this means you can use your current Optus SIM and simply insert it into your new phone.
If you’re experiencing SIM card, or activation issues, see SIM replacement & activation help.
