  • 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 Prepaid.

    1. 1. Head to and have your new Optus Prepaid SIM & some identification handy
    2. 2. Start by entering YOUR SIM NUMBER which is on the new Optus Prepaid SIM card
    3. 3. Enter YOUR DETAILS and be sure they match the same details of your current Mobile Service Provider’s record
    4. 4. Select KEEP YOUR NUMBER in section 3 - YOUR NUMBER where you enter your mobile number you’re keeping
    5. 5. Ensure you enter details that match with your current Mobile Service Provider’s record
    6. 6. Provide us authority to contact your current Mobile Service Provider and arrange the transfer

    Placing your order and switching your number can only happen during the business hours:

    • Monday - Friday: 08:00am - 08:00pm
    • Saturday: 10:00am - 06:00pm

    During these times it usually takes about 30 minutes, but can take up to 4 hours. If you have submitted your activation order outside of these times, your service will remain active with your current Mobile Service Provider and will be processed on the next available business day.

    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 it 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
    • Saturday: 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.

  • How does data rollover work?

    It's like taking what data you have left from your current recharge over to the next. All you need to do is recharge before your credit expires and the remaining data will be added to the data balance of your new recharge. Your new combined data expires when your new recharge does. And if you want to rollover your data again, you can - right up to a hefty 10GB. If you recharge over 10GB, you will forfeit any data over that limit. Here's an example of how data rollover works:

    Say you've got 100MB data left and your credit expires today. If you recharged today with $40, your 100MB gets added to your new recharge's data allowance, which is 4GB. This new combined amount, 4GB + 100MB, would expire in 28 days. And if there's any data left before the credit expires again, you can simply continue to roll it over.
