Boost’s $30 Prepaid SIM yields 20GB plus a 14GB bonus data for the first three recharges. The discount brings this down to just $15 for the first month. A $15 SIM normally gets between 2GB and 6GB with unlimited talk and text, so Boost’s 34GB offering on this promotion represents solid value. Of course, it is worth remembering you will pay full price from your second onward, and will have a lower allowance from your fourth. You can of course leave whenever, given the plan is prepaid. 

Likewise the $40 SIM pack comes with 30GB plus a 14GB bonus data for the first three recharges. With the discount, the first $20 recharge is worth 44GB of data on the Telstra network. 

These Boost Mobile deals are offered on a 28-day expiry on the entire Telstra 3G and 4G network and are available until June 30 for new customers. Here are some comparably priced prepaid recharge options for comparison.

How WhistleOut Works

To round out your discounted SIM, you can pick up a refurbished iPhone XS, iPhone 7 or Samsung Galaxy Note 9 at a 10% discount directly through Boost Mobile. Each phone undergoes a 72 point check before going to market, but just in case that's not enough all refurbished phones come with a 12-month warranty and a 30-day satisfaction guarantee. 

Handset costs range from $289 to $799 RRP so you could have your hands on an Apple device for as little as $260 in the EOFY sales.
