How do Data Add-ons work?

Data Add-ons allow your business to get extra data when you need to use it, so you can be sure to stay connected to your staff and customers while on the move.

You can get Data Add-ons for 24 hour periods, which can be accessed immediately from the time of request. They can be purchased to use in conjunction with any eligible Postpaid mobile plan with a limit of one Data Add-on per 24 hours, per service.

Your Data Adds-ons are billed monthly, aligning with your business mobile plan’s billing cycle and you can easily manage your data in My Optus App.

Available Add-ons

Available once off Data Add-ons for customers on all eligible Postpaid mobile 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.
