  • Can I keep my number when switching to Optus prepaid?

    Yes! Transferring a phone or service number between phone companies is called 'porting'. The following steps summarise what needs to happen if you want to keep your number and transfer it to Optus.

    1. Head to and have your new Optus Prepaid SIM & some ID handy
    2. Find the Optus SIM number located on your SIM or your SIM card holder
    3. Enter Your Details and be sure they match the details of your current Mobile Service Provider's record
    4. Select Keep Your Number when you've reached the Your Number section in Step 3 and enter your mobile number
    5. Make sure you provide us authority to contact your current Mobile Service Provider and arrange the transfer

    If you've already activated your SIM card and have been allocated a new number, you won't be able to replace the new number with your old number.

    How long does the porting transfer take?
    You can request to transfer to us online at any time; however a number will only 'physically' switchover during the times/days shown below. So if you make a request outside of these hours, your service will remain active with your existing provider until the next business day and then switchover. Switching normally occurs within about 20 minutes, but can take up to 4 hours during these times.

    Monday - Friday:

    08:00AM - 08:00PM


    10:00AM - 06:00PM

    What will it cost?
    Sometimes if you cancel a contract with another service provider early, they may charge you a fee. Be sure to check with your existing provider as Optus is not liable for any fees incurred as a result of you transferring your service from another carrier.
