Tangerine's new SIM-only deals boost data and slash prices on Telstra 5G plans – get 60GB from just AU$15 a month

If you’ve been running out of mobile data a lot on your current phone plan but don’t want to shell out more cash on a bigger data plan, then this deal from Tangerine Mobile may be what you’ve been looking for.

For a limited time, Tangerine is slashing the price of its SIM-only 5G plans by 50% for the first four months, starting with AU$15 per month for its base 30GB plan. The plan will then revert back to $30 from the fifth month onwards.

Moreover, each plan will also get double data for the first six months as well, boosting that base plan to 60GB for the period.

60GB SIM only plan | 30GB + 30GB bonus data for first 6 months | AU$15 p/m for first 4 months, then AU$30 ongoing

New Tangerine Mobile customers that sign up for any of its 5G SIM only plans until March 1, 2026 will get 50% off their monthly bill for the first four months, reducing this plan from AU$30 to AU$15. Those who sign up before February 3, 2026 will also get double their mobile data for the first 6 months, boosting the plan to 60GB within that period.

Minimum total cost: AU$15 (1 month) | Total cost for first year: AU$300

This deal above also beats our choice for the cheapest 365-day plan on the Telstra network, which is from Boost Mobile. Boost’s offering is for 240GB for AU$300, while Tangerine’s aforementioned plan, when extrapolated through a full year, provides 540GB of mobile data for the same amount. That averages out to AU$25 for 45GB per month.

Tangerine Mobile SIM plans also include a 1000GB data bank, allowing you to reserve any unused monthly data to accrue for use when needed later.

If you really want to push your data usage and easily fill up that data bank, the top Tangerine SIM-only plan will net you a whopping 320GB of mobile data for the first 6 months for AU$30 per month (and then AU$60 after four months, which is still a lot of data for that price!).

You won’t get this deal directly from Telstra, so if coverage is important to you, then this offer is hard to pass up.
