While Boost Mobile is not typically the cheapest Mobile Virtual Network Operator (MVNO) in Australia, its higher price is offset by the fact that it's the only third-party provider to offer access to Telstra's full network, which covers 99.7% of the Australian population.
But what if you could get that same access without the high cost? That's exactly what's on offer with Boost Mobile's latest deal for new customers, which slashes 65% off the price of its AU$49 prepaid SIM with 28 day expiry, while also providing stacks of bonus data.
Customers who sign up before April 20, 2026 can get Boost Mobile's AU$49 prepaid SIM with a whopping 125GB of data for just AU$17 — that's just under AU$0.14 per GB, which is the best dollars-to-data ratio you'll find in all of Australia.
Boost Mobile stands out because it's the only Telstra reseller that uses the entire Telstra network. That means you get the exact same coverage as Telstra, without any of those pesky wholesale network restrictions. This online-only deal for new customers offers insane value, providing 125GB of data for your first 28 days for only AU$17. This offer expires on April 20, 2026 and must be activated before May 4, 2026.
Total minimum cost is AU$17 (28 days) | Total cost for first year: AU$556
So what's the catch? Well, this price and data allowance is only available for your first 28 days of connection, with all future recharges costing the usual price of AU$49 for 35GB of data, which works out to AU$1.40 per GB.
That's not the most competitive offer around, but you always have the option of switching to another provider once the initial promo period is over.
If you're still keen on scoring a massive 125GB of data to play with over a 28-day period for price of a few cappuccinos, you should act fast — this offer is only available until April 20 and must be activated before May 4.
