I asked TA for a cheap Boost SIM and it's $4 after cashback. Offer ends 30/09/25 11:59pm AEST.
- 5G with International calls.
- Boost has reduced the price from $39 to $13 for the 25GB 28-day prepaid SIM.
SIM includes first recharge. 50GB for the first 3 recharges for new activations. 25GB from 4th recharge. Activate by 6 Oct 25, remaining recharges by 5 Dec 25. All for use in Aus. 28 day expiry. Incl. international calls.
My notes:
- Please note that letting the number expire and not recharging is eligible for cashback.
- Please don't deactivate or port away until you receive the cashback. Deactivate means requesting Boost to remove the number.
- Terms and conditions are from Telstra/Boost and apply to all cashback providers. Confirmed with the rep tightarse here, here and here.
- Cashback is on the purchase of the physical SIM only. You can convert to eSIM after you have received the physical SIM. Activate the physical SIM first, insert and then convert to eSIM.
- If you're a current Boost customer, you will need to port out into another provider and then port back into Boost. Please see the steps in my comment here.
TA's Tracking Tips:
- Prior to using TopCashback, disable/remove all 3rd party plugins (AdBlock, uBlock, Pi-hole, Honey, etc), VPNs, avoid browsers such as Brave and close any additional browser tabs.
- For iOS device: Apart from ensuring you’re not using an AdBlock app for Safari, the most important one is to ensure you have ‘Prevent Cross-Site Tracking’ turned off (see here).
What will stop me getting my cashback
- SIM must be activated within 30 days of purchase, and must not be deactivated until your cashback is payable. If the SIM is deactivated prior, Boost may decline cashback.
- Multiple SIM purchases need to be made as separate transactions. If there is more than one SIM in an order, it will result in an untracked purchase and the purchase will be ineligible for cashback.
- Cashback is ineligible on eSIMs, recharges, phones, bundles, accessories, $2 SIMs.
- Cashback is ineligible on use of any codes not approved and posted by TopCashback.
- Cashback is ineligible on use of gift cards for payment and/or purchase of gift cards.
- Cashback is ineligible on purchases made via the retailer's mobile app.
What else is essential
- Engaging with plugins such as Honey, AdBlock, uBlock, Pi-hole, VPNs, and browsers such as Brave may prevent your order from tracking.
- You must accept and allow all 3rd party cookies on the retailer's page if requested.
- You must always return to TopCashback and click the 'get cashback' button through to the retailer's website for each new transaction. Ensure the TopCashback link is the last one used to visit the retailer's website prior to completing your purchase.
- To be eligible for cashback, all transactions must be completed solely & wholly online and must not be assisted/negotiated via phone/chat/email. Failure to do so will cause tracking to fail and/or have cashback declined.
These cheap one month expire plans with huge data pack are so annoying, why not just extend to a year, I would make better use of the 50GB across a year in my cellular devices.
