How does Optus data sharing work on mobile and mobile broadband plans?

For each postpaid mobile or mobile broadband plan you purchase on the same account, Optus will provide you with 1 SIM.

The data from each 1 will form a pool that can be accessed by all plans on the account.

  • Example: You buy 2 Small Optus Choice mobile plans ($45 for 20GB a month) and a Small Data SIM plan ($15 for 5GB a month). You'll pay $105 per month for 3 SIMs, each of which have access to a shared 45GB every month. Each person can use as much or as little data as they'd like from this pool.

What about the Optus $5 data sharing SIM?

Optus used to have a $5 data sharing SIM, but it was discontinued in December 2016.

For $5, you could buy an extra SIM for another device to access your shared data pool.

These days, you have to purchase a new postpaid mobile or mobile broadband plan on your account to get a new SIM.

Currently, the cheapest option is a $15 mobile broadband plan from Optus that you'll have to pay for every month.

Is Optus data sharing a good deal?

Data sharing is a good deal from a convenience perspective, but performs worse in terms of value.

Pros

  • Everything is managed on the same account
  • The data pool is usually large enough that it won't get used up
  • Optus lets you continue to browse at max speed of 1.5Mbps with no excess data charges if you run out of shared data

Cons

  • No data controls means 1 person can use up all the data themselves
  • You need to buy a new postpaid plan (starting from $15 per month) to add a device to the data share
  • Much more expensive than buying individual plans from better value providers

If you and your family or friends were planning to sign up to Optus anyway, data sharing might come in handy for you.

But if you're considering signing up to Optus just to access its data sharing feature, you may want to reconsider. There are cheaper mobile plans out there that you can buy to cater for each individual's needs.
