Amaysim is an Australian mobile virtual network operator that offers SIM-only mobile phone plans and related telecommunications services using the Optus network.
Amaysim is an Australian mobile virtual network operator (MVNO) based in Sydney that provides SIM-only mobile phone services using the Optus 4G and 5G networks. They focus on no‑lock‑in, prepaid and subscription-style mobile plans, including standard talk/text/data plans, data‑only plans, and long‑expiry options. Customers can buy SIM cards online at amaysim.com.au or through retail partners, then manage their service via the amaysim website or mobile app, including usage tracking, plan changes, and payment details.
A charge from Amaysim may appear on your bank or card statement when you purchase a new SIM plan, recharge an existing service, or have auto‑renewal enabled on a 28‑day or long‑expiry plan. Common transactions include recurring plan renewals (every 28 days or on the plan’s expiry date), one‑off data add‑ons, international call or roaming packs, or pay‑as‑you‑go top‑ups. You might also see small temporary authorisation holds (often around $1) when you first add or update a payment method; these are used to verify your card and are usually reversed automatically within a few days.
If you’re unsure about an Amaysim charge, start by logging into your account at amaysim.com.au or via the amaysim app to review your active services, plan type, renewal date, and recent payments. Check your email for invoices or receipts from Amaysim sent at the time of purchase or renewal (they’re usually sent to the email address you used when signing up). For further help, you can contact Amaysim customer support through their website (help centre and live chat) or by phone; a support agent can confirm which number or service is linked to the charge, explain any add‑ons or extras, help you change or cancel auto‑renewal, and discuss any possible refunds or billing corrections.

Why am I seeing a recurring charge from Amaysim every 28 days?
Most Amaysim mobile plans are set up on a 28‑day renewal cycle, which means your plan fee is automatically charged to your saved payment method at the start of each new period. This can look like a monthly subscription even though it renews every 28 days. Log into your Amaysim account or app and check the “Plan & Usage” or “Billing” section to see your plan cost, next renewal date, and whether auto‑renew is turned on. You can switch off auto‑renew if you prefer to recharge manually.
What are the typical amounts Amaysim charges for mobile plans?
Amaysim’s charges usually correspond to the cost of your chosen SIM‑only plan or add‑ons. Their 28‑day mobile plans commonly range from around $10–$40 depending on the included data and features, while long‑expiry plans and larger data packs can be higher. If you see an amount you don’t recognise, compare it to your current plan price and any recent plan changes or data add‑ons in your Amaysim account. Detailed plan pricing and your past invoices are available under the billing or payments section at amaysim.com.au.
How do I cancel or stop future Amaysim charges?
To stop future Amaysim charges, log into your account at amaysim.com.au or in the app and turn off auto‑renew for your service. Your plan will remain active until the end of the current paid period, and will not recharge again unless you manually add credit or re‑enable auto‑renew. If you’re porting your number to another provider, once the transfer completes your Amaysim service will usually cancel automatically and further renewals should stop. If you’re unsure whether cancellation went through, contact Amaysim support to confirm your service status and next billing date.
Why do I see a small $0–$2 Amaysim charge or pending transaction?
Amaysim may place a small temporary authorisation on your card (often around $1) when you sign up, update your payment method, or sometimes when a payment is being verified. This is not a real charge and should automatically drop off or be reversed by your bank within a few business days. If the small amount remains on your statement longer than a week, contact your bank or Amaysim support with a screenshot of the transaction for clarification. These checks help ensure your card details are valid before processing actual plan or recharge payments.
How can I request a refund or dispute an Amaysim charge?
Because Amaysim services are generally prepaid, refunds are not guaranteed for change‑of‑mind after a recharge, but they may review cases such as duplicate charges, technical errors, or unauthorised transactions. First, compare the charge to your invoices and usage history in your Amaysim account to identify which service and plan it relates to. If you still believe the charge is incorrect, contact Amaysim via their help centre, live chat, or phone support with your account email, mobile number, and transaction details. They can investigate the payment and advise whether a credit, adjustment, or refund is possible under their policies.
How do I contact Amaysim about an unknown charge on my card?
Go to amaysim.com.au and access the Help or Contact section to reach support via live chat or online request form, or call their customer service number listed there. Have your full name, email address used to sign up, and the last four digits of the charged card handy, as well as the date and amount of the transaction. Support can search for any Amaysim service linked to your details and explain what the charge was for. If they cannot locate an account, they can advise next steps, including contacting your bank for further investigation.
Can an Amaysim charge be for a different mobile number or an old account?
Yes. Amaysim charges are tied to the payment method, not just to a specific phone number you remember. It’s common to see a charge for a secondary SIM (for a family member, tablet, or data‑only service) or for an older number you no longer actively use but which still has auto‑renew enabled. Log in with any email addresses you might have used, and check all services listed under your profile. If you can’t find the number, contact Amaysim support so they can search by payment details and help you close or disable any inactive services.
Why was I charged by Amaysim after I thought I had already cancelled?
If you cancelled close to your renewal date, your plan might have already auto‑renewed for the next 28‑day period before the cancellation fully processed. Amaysim services typically remain active until the end of the paid period, so you may still see one last charge. Log into your account to confirm that the service shows as cancelled or that auto‑renew is off and note the final expiry date. If you believe you were charged after cancellation should have taken effect, contact Amaysim support with the cancellation details and transaction date to request a review.
