Looking to squeeze some extra value out of your phone plan in 2026? Tangerine's ripe for that right now, thanks to its deliciously juicy summer sale on mobile plans, which provide Telstra 5G network access at prices that are almost too good to be true.

New customers who sign up to one of Tangerine's 5G SIM-only plans before March 1, 2026 can currently score a 50% discount for the first 4 months of service. That means its 30GB plan will cost you just AU$15 p/m during that promo period, before reverting back to AU$30 ongoing.

Best plan for most people:60GB* SIM only plan | 30GB + 30GB bonus data for first 6 months | AU$15 p/m for first 4 months, then AU$30 ongoing | Telstra 5G network

New customers who sign up for a Tangerine 5G SIM-only plan before March 1, 2026 can halve their monthly bill for the first 4 months, reducing the price of the 30GB plan from AU$30 p/m to just AU$15 p/m. Not only that, but by activating before February 3, 2026, you can also capitalise on a concurrent Double Data offer, boosting your allowance to a total of 60GB per month for the first 6 months. Tangerine's half-price promotion is available until March 1, 2026, while its Double Data promotion ends on February 3, 2026. T&Cs apply.

Total minimum cost is AU$15 (1-month) | Total cost for first year: AU$300

Taking the cheapest 5G plan (AU$30 for 30GB a month) as an example, savvy shoppers can net themselves 30GB of bonus monthly data (or 60GB total for those who don't have an abacus within reach) for the first 6 months of connection. And you'll only pay AU$30 AU$15 p/m during the initial 4-month period.

Need more perspective? The entry-level 5G plan detailed above works out to a total first-year cost of just AU$300 for 540GB of data — that's an average of AU$25 for 45GB a month — and that includes a 1000GB databank, so any unused monthly data will continue to accrue to use later on. Talk about an exceptional bargain!

Of course, those same half-price/double data promotions work across every other 5G SIM-only plan that Tangerine offers, meaning you can currently lock down 320GB of total monthly data for the staggeringly low price of AU$60 AU$30 p/m during those initial 4 months.

Take our word for it — prices this low that include this much data don't come around often (especially on the Telstra 5G Wholesale Network), which is why we'd seriously consider jumping on these deals before they expire!
