Is amaysim good value for a mobile plan in Australia?

For most people who want a prepaid SIM plan without a contract, amaysim is good value. Three things make the case, according to amaysim's own pages at the time of writing:

1. Price per gigabyte. The 120GB 28-day plan's ongoing price is $50, which works out to about 42 cents per GB.
2. Data you do not lose. Unused data rolls into an unlimited data bank that does not expire while you stay on your plan.
3. The Optus Mobile Network. amaysim lists the Optus Mobile Network as its network, so coverage follows the Optus map.

Who it suits less: people who want a phone bundled into a single monthly bill with in-store support, or households that want everything from one big telco. For them, Optus's own range is worth comparing, covered below.

amaysim plans in 2026: prices and inclusions

amaysim plans in 2026 come in four groups. These are the ongoing prices amaysim showed on 8 October 2026; new online services often get a discount on the first renewal, which amaysim lists alongside each plan.

Plan	Ongoing price (at the time of writing)	Renewal	Cost per GB	Notable inclusions
42GB	$35	28 days	about $0.83	5G at max 150Mbps; unlimited standard international talk and text to 28 countries
80GB	$40	28 days	about $0.50	Free Number Link; international talk and text to 42 countries
95GB	$45	28 days	about $0.47	Unlimited data banking
120GB	$50	28 days	about $0.42	5G at max 200Mbps; Free Number Link; international talk and text to 42 countries
10GB	$14	7 days	about $1.40	Short-term or backup use
150GB	$150	184 days	$1.00	Long expiry, one payment
240GB	$320	365 days	about $1.33	Long expiry, one payment
350GB	$350	365 days	$1.00	Long expiry, one payment
30GB data only	$25	28 days	about $0.83	Data-only plan for a tablet or modem

All of amaysim's voice plans listed unlimited standard national talk and text, eSIM support and unlimited data banking at the time of writing. amaysim also notes that 3G services are no longer supported, so check your phone is compatible before you switch.

Reading the table. The 28-day plans give the lowest cost per GB if you use a lot of data. Long-expiry plans cost more per GB, but you pay once and do not have to think about it for six or twelve months, which suits light users and people who want one payment a year.

amaysim plans: best deals in Australia for 2026

The best amaysim deals in Australia in 2026 usually come from timing your sign-up and following four steps in order.

amaysim's own offers. At the time of writing, amaysim's plan pages showed first-renewal discounts on several plans for new online services, each with an end date and "New online services only" in the terms. These change often, so check the plan page on the day you sign up.

The four steps to a lower mobile bill:

1. Compare prices. Pick the smallest plan that covers your real use, then compare it with the equivalent plan from Optus and other telcos.
2. Look for a promo code. Check amaysim's deals page and the amaysim offer on ShopBack for any current new-service offer.
3. Go through ShopBack. Open the amaysim page on ShopBack Australia, read the terms shown, then tap through. Going through ShopBack gets you a cash rebate on the same order, at the same store.
4. Pay with your best rewards card. If you use a rewards card, pick the one that suits a recurring bill, and check the card's own terms, as card rewards and any payment fees vary by card and telco.

Other telcos Australians compare for prepaid and SIM-only plans include Optus, Telstra, Vodafone, Boost Mobile, Belong and Circles.Life.

Optus and amaysim plans in Australia: how they relate

amaysim and Optus are linked. Optus bought amaysim's mobile business in 2021, and amaysim's site lists the Optus Mobile Network as its network, with links to the Optus coverage map and outage register. So the main difference between them is the plan and service style, not the towers.

	amaysim	Optus
Network	Optus Mobile Network	Optus Mobile Network
Prepaid plan lengths	7 days, 28 days, 184 days and 365 days, plus data-only	7 days, 28 days, 186 days and 365 days, according to Optus's prepaid SIM page
New-service offers	First-renewal discounts on selected plans for new online services	Bonus data on activation and the next two recharges on selected prepaid plans for new services
Other products	Phones, NBN and a mobile plus NBN bundle	Postpaid phone and plan bundles, NBN and 5G home internet

Who might pick amaysim. People who want a simple prepaid SIM on the Optus network, value unlimited data banking, and are happy to manage everything online or in an app.

Who might pick Optus. People who want a postpaid plan with a new phone on one bill, or who want to bundle mobile with Optus home internet. ShopBack Australia lists offers across several Optus products, including postpaid mobile and home internet. Check the Optus page on ShopBack Australia before you sign up.

Things to check before you switch to amaysim

• Coverage. Check the Optus coverage map for home, work and anywhere you travel often.
• Phone compatibility. amaysim says 3G is no longer supported, so make sure your phone supports 4G calling (VoLTE).
• Your number. amaysim offers a BYO (transfer) number option, so you can usually keep your number. Keep your old service active until the transfer is done.
• eSIM or physical SIM. amaysim's plans are eSIM ready, which can make switching faster on a compatible phone.
• Renewal cycle. A 28-day cycle means 13 renewals a year, not 12. On the $50 plan, that is $650 a year at the ongoing price.
• Fair use. amaysim's plan cards refer to its Fair Go Policy and say plans are for personal use in Australia.

How ShopBack lowers the price of a mobile plan

Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles. That is why going through ShopBack belongs in your sign-up routine as a step, the same way you would compare plans or check for a promo code.

A worked example (illustrative only). Say you sign up for a 365-day amaysim plan at $320. At an illustrative rebate of $20, the effective price of the year is $300. ShopBack telco offers are often a fixed dollar amount on an eligible new service rather than a percentage, so check the live offer and terms on the store's ShopBack page, because they vary by store and change over time.

How to do it:

1. Choose your plan on amaysim or Optus first.
2. Open the store's page on ShopBack Australia: amaysim or Optus.
3. Read the offer and terms shown, including any activation window for the SIM.
4. Tap through and complete the sign-up in that same visit, without switching to another tab or app.
5. The cash shows as pending and becomes available after the store confirms the eligible purchase.

amaysim's site lists the Optus Mobile Network as its network, and it links to the Optus coverage map and outage information. Optus bought amaysim's mobile business in 2021. Check the coverage map for the places you live, work and travel before you switch.

How much are amaysim plans per month?

Is amaysim cheaper than Optus?

They suit different needs rather than one always being cheaper. amaysim focuses on prepaid SIM plans with data banking, while Optus's own range spans prepaid plans from 7 to 365 days plus postpaid phone and plan bundles and home internet. Compare the plan you would actually use from each, including any new-service offer, then sign up through ShopBack Australia.

Does amaysim have a lock-in contract?

amaysim's SIM plans are prepaid and renew every 28 days, 7 days or on a long-expiry cycle, so there is no lock-in contract on the plan itself. If you also buy a phone, read the device terms separately before you sign up.

Which amaysim plan is the best value?

On cost per gigabyte, larger plans usually work out cheaper. At amaysim's ongoing prices at the time of writing, 120GB for $50 is about 42 cents per GB, while 42GB for $35 is about 83 cents per GB. The best plan is still the smallest one that covers your real monthly use, because unused data only helps if you keep the plan.

Can I keep my number if I switch to amaysim?

amaysim lists a BYO (transfer) number option, so you can usually move your existing number across when you sign up. Keep your old service active until the transfer is complete, and check your old provider's terms for any remaining device or contract costs.

Open the store's ShopBack page, read the offer and terms shown, tap through and complete the sign-up in the same visit. The cash comes back to your ShopBack account once the store confirms the eligible purchase.

Is cashback better than telco rewards points?

They do different jobs. Cashback lowers what you actually pay for an order and comes back as cash, so it works like a discount on the price, not like points or miles. Points are a reward you redeem later, often only with the same company.
