Our Data Add-ons are a once off data boost you can add to your shared data allowance when you're needing more data.

You'll have until the end of your billing cycle to use the additional data.

Here are our Once off Data Add-on amounts:

• $5 / 2GB
• $10 / 10GB
• $20 / 30GB

Each add-on can be added once every 24hrs, per mobile service you have on your account.

For example, if you have two mobile services on your account, you can add 2GB add-on on your first mobile number and an additional 2GB add-on on the other mobile number on the same day. The additional data will be shared at an account level across eligible services.

Note: Data can only be used within Australia, if you're looking for data when roaming please check out Optus Roaming Pass.
