amaysim eSIM and plans: prices, roaming packs and the network it runs on

What amaysim plans were listed on 10 November 2026?

amaysim sells SIM-only plans with no lock-in contract, renewing every 28, 184 or 365 days. Nearly every plan on its home page and eSIM page carried an introductory price when we read them, each with its own end date. The table shows the offer price, what the plan reverts to, and when the offer stops.

Two things to notice. The bonus data on the 75GB, 125GB, 220GB and 400GB plans is part of the offer, so the ongoing allowance is lower. And amaysim says the offers are for new online services only, with its terms and Fair Go Policy applying. Calling plans include unlimited national talk and text and international talk and text to 28 or 42 countries, depending on the plan, and every plan includes unlimited data banking.

This is desk research from amaysim's own pages. We have not bought or tested an amaysim plan.

Which network does amaysim use?

amaysim runs on the Optus network. Its home page describes 5G on the Optus 5G network, and its help pages say all amaysim mobile and data-only plans are powered by the Optus Mobile Network. Speeds are capped by plan: up to 150Mbps on most, and up to 200Mbps on the 125GB plan and the 100GB data plan. So your coverage in Australia is Optus coverage, and our Optus guide covers how that compares with Telstra.

How do you get an amaysim eSIM?

amaysim's eSIM page says every plan is eSIM ready and the eSIM number itself is free; you pay only for the plan. There are three routes:

• The amaysim app, which amaysim calls the easiest way to buy and activate an eSIM.
• The amaysim website, if you would rather not use the app.
• In store: amaysim says you can pick up an eSIM pack at any Woolworths or Big W.

To check your phone, dial *#06#; a compatible phone shows a 32-digit EID. amaysim says swapping a physical SIM for an eSIM works on iPhone XS (iOS 12) or later and Samsung Galaxy S20 (Android 10) or later, and it lists some phones that are not eSIM ready, including the Samsung Galaxy A13, A15 and A35. Bringing your own number, it says, gets the eSIM active in minutes. Set it up on a strong, private Wi-Fi connection.

Does amaysim have international roaming?

Yes, through prepaid roaming packs bought in the amaysim app. The packs last 365 days, which is unusual and useful if you travel a few times a year.

The destination count is not consistent on amaysim's roaming page: one banner says 120+ selected destinations and another says 90+. The country list itself runs to roughly 150 entries and includes in-flight roaming on partner airlines. Check that your destination is listed before you buy. The page sets out the steps as buy a plan, then buy a roaming pack in the app, and make sure roaming is switched on in your phone. It does not say what happens if you roam without a pack, so we could not confirm pay-as-you-go roaming rates. Turn data roaming off unless a pack is active.

When is a travel eSIM cheaper than an amaysim roaming pack?

For data, usually. The largest amaysim pack is $70 for 9GB, and Just Gigs is $50 for 6GB. Our verified prices, read on each seller's site in August 2026, were:

Japan

Airalo 10GB over 7 days for US$17, Nomad 10GB over 30 days for US$16, Saily 10GB over 30 days for US$17.99

United States

Airalo 10GB over 7 days for US$21.50, Saily 10GB over 30 days for US$22.99

Indonesia (Bali)

Airalo 10GB over 7 days for US$19, Nomad 10GB over 30 days for US$19

Even allowing for the exchange rate, 10GB on a travel eSIM costs well under the $50 amaysim asks for 6GB. Where amaysim wins is calls and texts on your own number, and the 365-day expiry: a $25 The Works pack bought once can cover two or three short trips if you mostly use Wi-Fi. A sensible split is a travel eSIM for data and your amaysim number left on for calls and texts, with data roaming switched off on that line. Our data roaming guide shows where the setting is, and the cheapest eSIM table ranks plans by cost per gigabyte.

Is amaysim any use to a visitor to Australia?

It can be. There is no contract, the eSIM can be bought online, and the 28-day plans are cheap while the offers run. The pages we read do not set out the identity checks for new services, so allow for that. If you are only in Australia for a week or two, compare it with the options on our cheap SIM card for Australia page.
