Was browsing the new Aldi catalogue this evening and saw this. Seems like a decent deal. Can't see it online yet. Updated to online link (thanks zzymurgy).
1 year "Super Pack". Unlimited standard calls, SMS, MMS, 42 GB data. Nothing in the conditions about the cost of extra data. On sale from Saturday February 4th.
Monthly sums: $20.75 per month. 3.5 GB per month - again nothing in the conditions about how the data works, I guess assume it's 42 GB up front until more info appears on-line. Aldi uses part of Telstra network and claims that covers 98.8% of Australian population.
@clse945111: Except Boost uses 700mhz and they recommend phones that have that band, and does not have 4GX access. Lack of 4GX is the difference between Boost and Telstra service. They have the same coverage map.
