I asked TA for $7 cashback. Costs $3 (after cashback). Cheapest Boost SIM currently.
- 5G with International calls.
- Boost has reduced the price from $39 to $10 & increased data to 75GB for the 25GB 28-day prepaid SIM.
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 (e.g. $2 Telstra SIM) and then port back into Boost. Please see the steps in my comment here.
For better tracking, use the TopCashback app, click the 'Get Cashback' pink button to the Boost website (not Boost app), use mobile data (not Wi-Fi) and Chrome browser.
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 any gift cards, vouchers, or store credit for partial or full payment. Cashback is also ineligible on purchase of any 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, DNS AdGuard, and browsers such as Brave may prevent your order from tracking.
- Accept and allow all 3rd party cookies on the retailer's page if requested.
- Return to TopCashback to click the 'Get Cashback' button for each new transaction.
- Transactions must be completed solely & wholly online and must not be assisted or negotiated via phone/chat/email. Failure to do so will cause tracking to fail and/or have cashback declined.
