Dodo
Dodo's mobile plans run on the Optus network, so coverage is what an Optus SIM gets: solid across the capitals and the larger regional centres, thinner off the main highways. There's no wholesale reduction to account for here, but there's no Telstra-grade regional reach either.
- $25 for 25GB is one of the sharpest entry prices on the Optus network
- Unlimited data banking, so unused data doesn't just evaporate at the end of the month
- No excess data charges at all
- International call credit on every tier, $100 to $400 depending on the plan
- Month-to-month, no lock-in
- Only three tiers, so there's nothing above 80GB
- 5G capped at 150Mbps across the range
- The advertised price is a four-month promotional rate on two of the three plans
- Optus coverage, which is a real limitation if you spend time well outside the cities
Dodo sells three SIM-only mobile plans on the Optus network. Small range, sensible design. The two things that stand out are unlimited data banking and no excess data charges, which together mean the allowance on your plan is a soft ceiling rather than a cliff you fall off.
One note before the prices: the site is at dodo.com, not dodo.com.au.
Current plans
Plan | Data | Ongoing price | International credit |
|---|---|---|---|
25GB | 25GB | $25/month | $100 |
40GB | 40GB | $30/month | $200 |
80GB | 80GB | $40/month | $400 |
All three are month-to-month with no lock-in, unlimited standard calls, text and MMS, 5G capped at 150Mbps, unlimited data banking, no excess data charges, and $10 per gigabyte daily roaming.
Prices confirmed 26 August 2026. Watch the promotional pricing: at that check, the 40GB plan was running at $15/month for the first four months and the 80GB at $20, both ending 27 October 2026. The table above shows the ongoing rate, which is what you'll actually be paying by month five.
Compare these against every other current plan, including the other Optus-network options, in the full comparison table.
Coverage
Optus network, no wholesale caveat. That puts Dodo in the same coverage bracket as Amaysim, iPrimus and every other Optus-based brand, and the Optus network hub has the full list. If your postcode is well outside a regional centre, this is the network to be cautious about, and a Telstra-based brand is the safer buy regardless of price.
APN settings
Dodo's APN settings are confirmed from Dodo's own support pages, checked 26 August 2026: the APN is internet, the same one every Optus-network brand uses. Worth knowing that Dodo's settings page is visibly old, so we've only published the values that match what we've independently confirmed for the Optus network, and left the MMS port blank rather than repeat a number no current source backs. Most handsets configure themselves anyway.
The honest verdict
For $25, Dodo's entry plan is one of the better deals on the Optus network, and the no-excess-charge policy takes the anxiety out of a month where you tether more than usual. Data banking on top of that is a real feature, not a marketing line, because it means an underused month isn't wasted money.
The ceiling is the problem. 80GB is the top of the range, so a heavy user runs out of Dodo before they run out of budget. If that's you, Aussie Broadband goes to 180GB on the same network. And as always with the promotional pricing, judge the plan on the ongoing rate, not the number on the banner.
Frequently Asked Questions
- What network does Dodo mobile use?
- Optus. Coverage matches an Optus SIM.
- What happens if I use all my data?
- Nothing you get billed for. Dodo doesn't charge for excess data. It also banks unused data without a cap, so an underused month carries forward.
- Is the advertised price the ongoing price?
- Not always. When we checked in August 2026, the 40GB and 80GB plans were running at half price for the first four months. The prices on this page are the ongoing rates, which is the number worth budgeting on.
- Does Dodo charge for international calls?
- Each plan carries an international call credit, $100 on the 25GB plan, $200 on 40GB and $400 on 80GB. That's a credit against call charges, not unlimited calling.
