Boost Mobile

To order a Boost Mobile SIM, pick your SIM tier, then order through ShopBack before you pay: ShopBack Cashback works like a discount, only easier than a promo code. Boost Mobile Australia is a prepaid mobile carrier operating as a Mobile Virtual Network Operator (MVNO) on the full Telstra retail network, not the wholesale slice used by other MVNOs. This means Boost customers access the same coverage footprint (around 98 percent of the Australian population) as Telstra prepaid customers, but at MVNO-tier prepaid pricing. Boost is positioned as the Telstra-network value alternative alongside Belong (also on Telstra), Aldi Mobile (Telstra wholesale), and Woolworths Mobile. Cashback runs on eligible new SIM orders via the ShopBack Boost Mobile merchant page, at the rate shown there.

Yes. Boost Mobile is the only MVNO in Australia that operates on the full Telstra retail 4G and 5G network, matching the coverage footprint used by Telstra's own retail prepaid customers. This is a key differentiator versus Aldi Mobile and other Telstra-network MVNOs that use the Telstra wholesale coverage tier. For rural, regional, and coastal Australians who need Telstra-tier coverage without paying Telstra retail prices, Boost is typically the more efficient path. Verify current coverage on boost.com.au against your postcode before switching.

Boost long-expiry plans (typically 12-month or 365-day) let customers pay once upfront and use the included data, calls, and texts across the full expiry period. This suits low-usage prepaid customers, secondary SIMs, kids' first phones, and travelling family members. The 365-day plans typically bundle a large data allowance intended to average across the year. Compare against a rolling 28-day recharge cycle to see which shape is cheaper for your actual usage. See the Boost long-expiry page for current inclusions.

Boost typically offers data rollover on eligible plans when you recharge before your current plan expires. Unused data from the previous plan is added to the new plan's balance up to a capped amount, and rollover is lost if you miss the recharge date. Boost's website lists the current rollover terms and caps.

All four run on Telstra network infrastructure but differ on the coverage tier and pricing model. Telstra Prepaid uses the full retail network at the highest price point. Boost also uses the full retail network at MVNO pricing (typically the cheapest path to full-Telstra-coverage prepaid). Belong (Telstra-owned) sits between on price with slightly narrower coverage. Aldi Mobile uses the Telstra wholesale coverage tier at the lowest price but with narrower rural coverage. For rural users prioritising coverage, Boost is typically the sweet spot; for city users prioritising cost, Aldi Mobile typically wins.

Boost typically includes standard international calls to selected countries on most 28-day and 12-month prepaid plans (verify the country list on the plan page). International roaming outside Australia is available on a top-up basis with country-specific data day-passes. For heavy international users, compare Boost's included country list against Amaysim, Lycamobile, and Lebara's inclusions before choosing.

Yes. Boost customers on 5G-enabled plans and compatible handsets access Telstra 5G at no extra charge, matching Telstra retail 5G coverage. 5G is available in most major metro areas and expanding regional centres. Check 5G footprint against your postcode on boost.com.au before assuming coverage.

To port your existing mobile number to Boost, order a Boost SIM through the site or app, enter your existing number and current carrier details in the porting step, and follow the SMS verification. Port typically completes within a few hours during business hours. Keep your outgoing carrier until the port completes, and check whether you are mid-contract with your current carrier before switching, to avoid early termination fees.

Go through ShopBack before you pay and the Cashback tracks to your ShopBack account. On your phone, open Boost Mobile from the ShopBack app and finish the SIM order there. Cashback is a fixed amount per SIM tier, at the rate shown on ShopBack's Boost Mobile page at shopback.com.au/boost-mobile.

Order through ShopBack before you pay, and the current Cashback is shown on the ShopBack Boost Mobile page.

Start from the ShopBack Boost Mobile page in the ShopBack app, on shopback.com.au or via the browser extension, then order a physical Boost prepaid SIM on boost.com.au. The ShopBack listing pays a fixed amount per SIM tier, and the amount for each tier is the one shown on this page on the day you order. The Cashback is for new Boost customers.

The ShopBack Boost Mobile offer has three parts, all shown on this page. First, Cashback on a new Boost prepaid SIM order: a fixed amount per SIM tier as shown on this page, paid after confirmation. Second, gift cards: check shopback.com.au/gift-cards for any Boost Mobile gift card or swap card offer. Third, upsizes: when an upsize runs, the higher rate shows on this page next to the SIM tiers, and the figure on the page on the day you order is the one that applies.

The effective price is what you pay at checkout minus the Cashback that comes back. Take the price of the 12-month SIM you choose on boost.com.au and subtract the Cashback amount for that SIM tier, which is the amount shown on ShopBack's Boost Mobile page. The Cashback is paid to your bank account or PayPal after it confirms within the confirmation time shown on this page, and any Boost online sale price lowers what you pay at checkout.

The current Cashback and the SIM tiers listed are shown on the ShopBack Boost Mobile page. Once your Cashback is available, you withdraw it from your ShopBack account to an Australian bank account or PayPal.

The current Cashback is shown on the Boost Mobile page on ShopBack. A SIM that is not one of the listed tiers earns at the lowest Cashback tier. Porting your existing number, data rollover and Telstra 5G do not change the Cashback.

If you need two SIMs, make them separate transactions, since ShopBack states multiple SIM purchases must be made separately.

Boost does not run coupon codes on its plans, so pick your SIM, then order through ShopBack before you pay, where ShopBack Cashback works like a discount, only easier than a promo code. Its deals are online price cuts applied on boost.com.au with no code, usually on new-activation SIMs with ongoing recharges at the full price, so check boost.com.au on the day. Check the ShopBack Boost Mobile page on the day to see which SIM tiers are listed. Bonus data on new activations is a Boost inclusion and does not affect Cashback.

Pick Boost if coverage outside metro areas matters: Boost runs on the full Telstra retail 4G and 5G footprint, while amaysim runs on the Optus network, which drops out in parts of regional Victoria and WA. Pick amaysim if you want the cheapest metro entry plan: our MVNO comparison puts the amaysim entry tier around A$15 for 10 to 15GB on a 28-day cycle, against Boost's A$28 for 8GB or A$39 for 60GB on the first 6 recharges (as listed on each brand's site in October 2026). Both sell 365-day plans and both earn ShopBack Cashback on an eligible new SIM through their own ShopBack pages (shopback.com.au/boost-mobile and shopback.com.au/amaysim-mobile), at the rate shown on each page.

felix Mobile sells a single A$35 a month plan with unlimited data on the Vodafone network, soft-capped at 20Mbps (as listed on felix's site in October 2026), so it wins for anyone using more than about 60GB a month in metro areas. Boost's closest plan is the A$59 28-day SIM with 105GB on the first 6 recharges and a 250Mbps cap, or the A$74 SIM with 150GB and no speed cap, both on Telstra 5G (as listed on boost.com.au in October 2026), so Boost wins when you want speed or regional coverage rather than unlimited volume. If you stream in 4K or tether a laptop daily in a city, felix is the cheaper answer; if you travel regionally, Boost is. Both have ShopBack pages (shopback.com.au/felix-mobile and shopback.com.au/boost-mobile) paying Cashback on eligible new sign-ups at the rate shown on each.

ALDI Mobile uses the Telstra wholesale network and its entry 30-day plan sits around A$15 for 10 to 15GB in our MVNO comparison (as listed on ALDI Mobile's site in October 2026), so it is the lowest starting price on a Telstra-based service. Boost uses the full Telstra retail network with 5G and sells its cheapest 28-day SIM at A$28 for 8GB, with the A$39 60GB SIM the value step up (as listed on boost.com.au in October 2026), so Boost costs roughly A$13 to A$24 more per cycle for a wider footprint and 5G access. Pick ALDI Mobile for a metro light user on a budget; pick Boost for anyone who drives regional highways or wants 5G. Boost earns ShopBack Cashback through shopback.com.au/boost-mobile; our comparison table marks ALDI Mobile as retailer-dependent, so check shopback.com.au for a current ALDI Mobile listing before assuming Cashback there.

As listed on boost.com.au in October 2026, the 28-day range for new activations was: A$28 for 8GB ongoing; A$39 for 60GB on the first 6 recharges then 30GB; A$49 for 75GB on the first 6 recharges then 45GB; A$59 for 105GB on the first 6 recharges then 55GB; and A$74 for 150GB on the first 6 recharges then 100GB, with occasional online sale prices on the SIM itself. The bonus data requires activation by 2 November 2026 and the remaining bonus recharges by 5 April 2027. All include Telstra 5G access with a compatible device and data rollover if you recharge before expiry. The $49 Prepaid SIM is one of the tiers named on the ShopBack Boost Mobile page, with Cashback at the rate shown there.

As listed on boost.com.au in October 2026, Boost sells three long-expiry SIMs: the $180 SIM with a 6-month (186-day) expiry and 160GB on the first recharge then 100GB; the $300 SIM with a 12-month (365-day) expiry and 290GB on the first recharge then 240GB, which Boost works out as 24GB for A$25 a month paid upfront; and the $365 SIM with a 12-month expiry and 365GB ongoing, or 30GB for A$25.42 a month, with the 6-month and 12-month SIMs sometimes on online sale. All three carry a 150Mbps download speed cap on 4G and 5G. The $365 Prepaid SIM and the $180 Prepaid SIM are both named tiers on the ShopBack Boost Mobile page, so a long-expiry SIM is the natural way to combine one annual payment with Cashback at the rate shown.

Only the A$74 28-day SIM (150GB on the first 6 recharges, then 100GB) is listed on boost.com.au with no speed cap on 4G or 5G as of October 2026. The A$59 SIM carries a 250Mbps download cap, and the A$28, A$39 and A$49 28-day SIMs plus all three long-expiry SIMs carry a 150Mbps cap (as listed on boost.com.au in October 2026). For most phone use 150Mbps is more than a streaming service needs, so the uncapped plan mainly suits hotspot and tethering users. Whichever you choose, Cashback through the ShopBack Boost Mobile page depends on the SIM tier, not the speed cap.

Skip it if you are already a Boost customer, since the Cashback offer is for new Boost customers. Skip it if you want unlimited data in a city, where felix Mobile at A$35 a month is cheaper than Boost's A$74 uncapped SIM (as listed on each brand's site in October 2026), or if you want a handset bundled with a plan, which Boost does not sell on a prepaid SIM. Boost is the right pick when you need the Telstra retail footprint, a 365-day plan and a fixed Cashback amount from ShopBack on one order.

Yes on both. During activation you choose to port your existing number from your current carrier. Every Boost SIM listed on boost.com.au in October 2026 states that the SIM includes the first recharge, so the A$39 or A$300 you pay at checkout covers the first cycle. Keep your old service active until the port completes. Boost's plan pages also note all inclusions are for use in Australia and the A$28 8GB plan excludes international calls, so check the plan page if you call overseas.

For the first 28 days, yes. Boost sometimes runs online sale prices on its $49 28-day SIM for new activations, and when it does that SIM can undercut Boost's own A$28 entry SIM while giving far more data. The catch is the ongoing recharge price of A$49, so from month two you pay the full rate unless you move down a tier. If you order a sale-priced SIM through the ShopBack Boost Mobile page, check that page on the day to see which SIM tiers are listed.

Boost runs these as online-only sale prices on its $365 12-month and $180 6-month SIMs for limited windows, with ongoing recharges at full price, so check boost.com.au on the day. Our Australia sale calendar flags EOFY in June, Black Friday in late November and Boxing Day as the windows when telco discounts usually deepen, and Boost's own promotions can run for weeks or months. Buy a long-expiry SIM when a sale price and the ShopBack tier line up, checking that the SIM is one of the tiers named on this page; the rate shown there on the day you click is the one that applies.

The SIM price is the same, because the ShopBack click-through lands you on boost.com.au at Boost's own online prices, including any online-only sale prices. Online-only sale prices are also not available in store. The difference is what comes back: an online order started from the ShopBack Boost Mobile page earns a fixed Cashback amount for the SIM tier shown on this page. So the cheapest route is the online order from ShopBack, activated within the window shown on this page as a new Boost customer.

Boost is cheaper than Telstra because it is a prepaid-only brand that pays Telstra for access to its network and sells SIMs online with lean overheads, instead of funding a store network, postpaid contracts, handset repayments and bundled extras. You still get the full Telstra retail 4G and 5G footprint, so for most people coverage is the same. What you give up is the extras: Boost sells SIM-only prepaid plans, with no handset on a plan and no bundled entertainment. If you want a new phone on a plan or in-store help, Telstra can be worth paying more for. If you already own your phone and want Telstra coverage on a SIM-only plan, Boost usually wins.
