Make the most of your smartphone.
Data Add-ons allow you to get extra data as and when you need to use it, so you can do more of the things you love online.
How do Data Add-ons work?
You can have a Data Add-on for as little as a day and you can manage your Data Add-ons in My Optus app, so no need to call us to make changes. If you have shared data on the account, then data from monthly Once off Data Add-ons will be shared by all eligible services on the account. The Unlimited Data Day Add-on cannot be shared with other services on the account. Once the data from the Data Add-on and any mobile plan data has been used, you won't be charged for excess data, instead your data speed will be slowed to a max. of 1.5Mbps with Endless Data. You can restore your data speeds by adding more data to your account in My Optus app.
Available Add-ons
Available Data Add-ons for eligible customers on all eligible month-to-month SIM plans.
Unlimited Data Day cannot be shared with other services on the account. See T&Cs below.
For all other plans, go to My Optus app or My Account within the Add-ons section.
