Three numbers to separate
Write down the introductory charge, ordinary charge and number of eligible promotional renewals. Then do the same for data. On its official page checked on 5 October 2026, amaysim's 80GB offer showed $13 for the first renewal and $40 for later 28-day renewals, for eligible new online services, with an offer end date of 11 October 2026.
Boost's $49 plan showed 75GB for the first six eligible 28-day recharges and 45GB from the seventh. Its conditions included a new activation deadline and a later deadline for remaining promotional recharges. The price and the data do not necessarily change at the same time.
Our filter uses the ordinary amount
If you need 60GB every period, a plan that drops to 45GB is excluded even while its bonus is active. If you can only spend $35 each renewal, a first-period discount on a $40 plan does not make that plan fit. You can change those constraints and recalculate.
