Boost Mobile promo codes and coupon codes in September 2026
5 active vouchers to help you save with the latest Boost discount codes
I’ve been an Editor with CupoNation Australia since 2023, where I use my savings expertise to curate Boost Mobile offers and refresh the page twice a week with verified codes. From what I’ve seen, you should look at their SIM and Phone bundles on refurbished devices. With prices between $200 - $1,000, you can get a refurbished iPhone with a free SIM. Buying both separately would cost hundreds more, so bundling them is one of the smartest moves for year-long savings.
Boost Mobile was founded in 2000 by Peter Adderton and is a popular prepaid mobile service provider in Australia. With over 9,000 stores nationwide, the brand provides SIM cards that are easily accessible to customers.
Known for its flexible and generous long-expiry SIM plans, the brand has created a trusted presence among users since the 2000s. Boost Mobile also boasts plans with unlimited calls and texts, transparent pricing, and affordable prices, making it a favourite among Aussies who are looking for premium phone service without the high price tag.
The Boost Mobile app makes it simple to manage your account from anywhere. Available for free on both Android and iOS, it allows you to order new SIMs or eSIMs, recharge existing ones, and track your call, text, and data usage for up to six months. Having the app on hand also makes it easier to grab roaming plans or special offers while you are on the go. We recommend keeping it installed so you can act quickly when time-sensitive deals are released.
If you are travelling overseas, we suggest getting Boost Mobile’s international roaming plans. These plans can keep you connected for less. With rates starting from under $3 a day, you can make calls, send texts, and use data in over 40 countries. Plans can be purchased directly through the app, making it quick to set up before you travel. To stretch your budget further, activate roaming only for the days you need it and take advantage of local Wi-Fi when possible.
The brand's Deals page is your go-to for all current offers, from discounted SIMs to bundle freebies. We have seen deals like free SIMs with refurbished devices, a 28-day 65GB SIM for just $39, and roaming services from under $3 per day. Offers update regularly, so it pays to check this page often and grab what you need while it is available. Combining a SIM sale with discounted devices can deliver some of the best value.
Boost Mobile offers free express shipping on all orders, from devices to SIM cards, with delivery in three to seven days. It’s a quick, cost-free way to get connected without visiting a store.
Buying a refurbished device from Boost Mobile comes with a free SIM valid for 28 days, which can be recharged later. This adds instant value to your purchase, letting you use your new phone straight away.
