The amaysim 28 day plans are the bulk of that catalogue. Each is a named data amount, a price, a 28 day cycle, a network and a contract term, and none of them carries a lock-in contract. The renewal question is the same for all of them: what does the second cycle cost?
The 28 day catalogue as published
| Plan | Price | Cycle | Data |
|---|---|---|---|
| $25 plan | $25 | 28 days | 30GB |
| $30 plan | $30 | 28 days | 15GB |
| $35 plan | $35 | 28 days | 42GB |
| $40 plan | $40 | 28 days | 80GB |
| $50 plan | $50 | 28 days | 120GB |
Each of those rows is published with the same three qualifiers: Optus 4G/5G, no lock-in contract, and for most of them unlimited talk and text. The $25 30GB plan is the exception in the catalogue in that its data allowance is the named feature rather than a talk and text pairing.
What triggers the next recharge
Prepaid credit does not roll itself forward. The next cycle starts when the customer recharges again, and the catalogue does not publish a separate renewal price, an auto-recharge default, or a rollover rule for these entries. Treat the listed price as the price of the next cycle unless the provider says otherwise in your account.
The comparison that actually decides it
Because the cycle is the same length across the catalogue, this is the rare case where a direct price comparison is valid: $25 for 30GB is cheaper per GB than $50 for 120GB, while $50 buys four times the data. Work out your own monthly data use first, then take the smallest plan that covers it.
What we could not verify. Where a provider has not published a figure we mark it unknown rather than estimate it. Re-read the provider page linked below on the day you decide.
