Data Sharing

Use your plans’ data across devices
By combining any of our latest eligible month-to-month Mobile and Mobile Broadband plans onto one account, Data Sharing will allow you to share your total monthly data between devices.

Data Sharing for me

Are you one of the many out there who have multiple devices that all use heaps of data? All the social buzz on your mobile, catching up on TV via your tablet on the commute home - and that's just the tip of your digital iceberg!

Data Sharing gives you the convenience of one account and all the data inclusions of your connected services in one big pool to share. You can connect any combination of eligible mobile SIM and mobile broadband plans.

Note: Optus Choice Plus, Optus Plus Family, Optus Plus Kids, Optus Choice Plus Data and Optus Choice Plus Watch plans can only share data with each other and not any other plans.

More great news:

  • With Endless Data don't pay excess data charges, instead slow down your data speed to a max. of 1.5Mbps when you hit your limit.
  • Need a Data Boost? Return to full data speed when you reach your limit by adding more data or an Unlimited Data Day on eligible plans.
  • Unlimited standard national talk and text on our eligible mobile plans.
  • We'll send you usage alerts and you can monitor your spend through the My Optus app.

Got more burning questions?

Need some more information on all things relating to the Data Sharing?

Is there a limit to the number of plans I can connect to a Data Sharing?

The good news is you can have as many eligible mobile and mobile broadband plans on the same account as you like (subject to credit check approval), allowing you to combine and share data across all the devices connected to the one account.

Optus Choice Plus, Optus Choice Plus Data, Optus Plus Family and Optus Plus Kids plans can only share data with each other.  Check your CIS document or My Optus app to check your plan.

How can I keep track of my usage?

We'll send you SMS usage alerts once you've reached approximately 50%, 85% and 100% of your combined shared data inclusion. If you are eligible and have automatic $10 per 1GB turned on, once you have used your total shared data allowance we will send you an SMS at 50%, 85% and 100% of any additional 1GB of data used.
And you can check usage by:

  • Visiting My Account.
  • Downloading the My Optus app.
     
Does my Data Sharing’s data roll over from month-to-month?

No, any unused data in Data Sharing expires at the end of the your payment cycle.

Can I share data using my existing Optus mobile phone or mobile broadband plan?

Your services will need to be on the same account to get Data Sharing and you will need to ensure that your services are connected to eligible plans. The eligible plans include:

  • Optus Choice mobile & Data SIM plans
  • Optus Choice Family and Kids plans
  • Optus One mobile plans
  • Data Plans (released after 9th of September 2019)
  • My Plan Plus mobile phone plans
  • My Plan Plus SIM Only plans
  • My Plan Flex leasing plans
  • My Mobile Broadband Plus plans
  • Promo Plus plans
  • Promo Flex plans
  • My Promo Plus 12M SIM plans
     

If your services are not on an eligible plan, then to take advantage of Data Sharing you will need to change to one of the plans listed above and there may be cancellation or other fees payable.

If your services are on eligible plans but different accounts you will need to contact Customer Care on 133 937 to have them put on the one account.

Can I share data using the new Optus Choice Plus plans?

Your services will need to be on the same account to get Data Sharing and you will need to ensure that your devices are connected to eligible Optus Choice Plus, Optus Choice Plus Data, Optus Plus Family and Optus Plus Kids plans.

What if I don’t want to share my mobile or mobile broadband plan’s data?

Eligible Postpaid plans on the same account will combine their included data and any extra data into a single pool.

If you don't want to share your data between your services they'll need to be on separate accounts.

Can I share my included minutes?

Your plan’s included minutes are not shareable. A plan’s included minutes can only be used by the mobile service to which they are connected, but remember, any mobile service connected to our latest month-to-month mobile plans, will get the benefit of unlimited minutes to standard national Australian mobiles and landlines, 13/1300 numbers and voicemail.

Can I share included SMS/MMS?

Your included SMS/MMS are not shareable. A plan’s included SMS/MMS can only be used by the mobile service to which they are connected. Remember, any mobile service connected to our latest month-to-month mobile plans will get the benefit of unlimited standard national SMS/MMS. You also get unlimited international standard SMS/MMS to selected countries on selected month-to-month mobile plans.

Can I stream Mobile TV and Music without using my plan’s data on all my devices if I Data Share?

No, you can only stream Mobile TV and Music without using your plan’s data on services which have the month-to-month entertainment option(s) activated.

Data Sharing

If you have more than one eligible plan that shares data on the same account, the included monthly data allowance will combine and be shared by all eligible services on that account. This data can also be shared with any existing Data Sharing plan. Any unused data in the account expires at the end of each payment cycle.

Data Add-ons

Available on selected mobile plans. Each add-on can be added once per 24 hrs, per service. You can access your Data Add-ons as soon as you request it. You may automatically be charged via card on activation of the add-on, if no payment is made you will still have access to the add-on and the amount will be added to your next monthly invoice. The inclusion of your Data Add-on is added to your shared data allowance on your account. Data is counted in KB increments and includes uploads and downloads. Any unused data is forfeited and cannot be rolled over to your next payment cycle. Usage alerts are sent at 50%/85%/100% of your shared data via SMS or email. Add-on expires if data used or at end of payment cycle (whichever is first). Data can only be used in Australia.

Endless Data

If shared data allowance is exceeded, all shared data services on your account will be slowed to a maximum speed of 1.5Mbps (suitable for general internet browsing and music streaming, however some activities such as video streaming may see increased buffering and loading times). Usage while slowed is unmetered. Usage may be delayed up to 4hours. Applies to data usage in Australia only.

Usage alerts

Usage alerts are typically real-time but delays of up to 48 hours may be experienced. You will receive alerts in Australia and while roaming overseas via your nominated email. However, you can change your preferred method of receiving usage alerts and service notifications anytime by visiting My Account. To learn more about usage alerts, click here.
