Amaysim runs entirely on the Optus network as an MVNO, so coverage matches Optus's own footprint. Strong in cities and major regional centres, thinner once you're well outside them. Check Optus's own coverage map, not general amaysim marketing, before deciding.

  • No lock-in, 28-day recurring cycle
  • Simple four-tier lineup, easy to compare
  • Unlimited data banking (rollover) on every plan
  • Unlimited international SMS/MMS to 28 countries
  • eSIM supported
  • The 15GB plan's promo price is a third of its ongoing rate: $10 for the first cycle, then $30 every cycle after
  • Optus network only, so the same regional weak spots as any Optus-based SIM
  • 5G speed capped at 150-200Mbps depending on plan

Amaysim is a SIM-only mobile brand running on the Optus network, with four data tiers and the same 28-day recurring structure across all of them: no lock-in contract, cancel any time, unused data rolls over indefinitely.

Current plans

Four SIM-only tiers, 28-day recurring, no lock-in:

All four include unlimited standard national talk and text, unlimited international SMS/MMS to 28 countries, and unlimited data banking so unused data carries over rather than expiring. The 80GB and 120GB tiers add Free Number Link. 5G speed is capped: 150Mbps on the 15GB, 42GB and 80GB plans, 200Mbps on the 120GB plan.

The 15GB plan is the one to budget carefully for. Its advertised $10 is a one-cycle intro rate that jumps to $30 from the second renewal on. The other three tiers are priced the same from the first cycle.

Compare these against every other current plan, including other Optus-network options, in the full comparison table.

APN settings

Amaysim mobile uses its own APN profile, separate from Optus's own. Amaysim's APN settings has the exact values, confirmed directly from amaysim's own help centre.

The honest verdict

Amaysim is decent value once you're looking at the real ongoing price on the 15GB plan rather than the promo rate. The unlimited data banking is a genuinely useful feature most budget SIM-only brands don't bother with. It suits someone who wants Optus-network coverage without a contract and is comfortable checking the second-cycle price before signing up. Anyone chasing the cheapest possible ongoing rate should compare it directly against Optus itself and other Optus-network resellers before committing.

Frequently Asked Questions

What network does Amaysim run on?
Optus. Amaysim is an MVNO reselling Optus's network, so coverage is identical to an Optus SIM: solid in metro and regional centres, weaker in remote areas.
Why is Amaysim's 15GB plan so much cheaper in the first month?
It runs a discounted first 28-day cycle at $10, then reverts to $30 every cycle after. The advertised $10 is the promo rate, not what you'll actually pay ongoing. The 42GB, 80GB and 120GB plans don't carry the same promo and are priced flat from the start.
Does Amaysim support eSIM?
Yes, all current SIM-only plans are eSIM ready.
Is there a lock-in contract?
No. Plans recur every 28 days with no lock-in. Cancel or switch plans at any time.
