Use My Optus, visit optus.com.au/recharge, or call 555 from the Optus Prepaid SIM—even with a $0 balance. Confirm the mobile number and recharge option before paying.
Recharge without guessing the amount
Check the current plan
Open My Optus and note the plan name, balance and expiry. An advertised starter-SIM offer may be for a new service rather than your existing recharge.
Choose the recharge method
Use the app or official recharge page. If you cannot get online, call 555 from the service. Follow its available payment prompts.
Check the recipient and inclusions
Read the number, price, data and expiry on the confirmation screen. With a voucher, confirm the voucher suits the plan before redeeming it.
Keep the receipt
Save the confirmation and check the account afterwards. A bank entry alone does not tell you which phone received the recharge.
Open the official Optus recharge page directly. If you are topping up a relative’s phone, have them read the number out and repeat it back before you confirm.
SMS and AutoRecharge
Optus lists Menu to 9999 for its SMS menu. Its terms allow AutoRecharge management through that menu or 555 when you have a saved payment method. The published keyword is Menu; do not rely on the old article’s RECHARGE instruction.
Some current Flex Plus offers are AutoRecharge-only. They require a payment card and do not accept manual recharges. Check your specific plan before turning AutoRecharge off. On balance-triggered AutoRecharge, Optus says expiry resets and unused days or ineligible inclusions are forfeited.

If the recharge does not appear
The payment is pending
- Check
- The transaction status and recharge confirmation.
- Next
- Keep the reference and ask Optus to trace it before paying a second time.
The voucher fails
- Check
- The digits, expiry and eligible recharge product.
- Next
- Keep the voucher and purchase receipt; contact the retailer or Optus rather than discarding it.
The allowance is smaller than the offer
- Check
- Whether the offer is for new activations or requires AutoRecharge.
- Next
- Compare your service’s eligibility with the offer terms; a shop display is not proof that an existing number qualifies.
Compare recharge options
The table is supplied by Wireless Choices. Check the expiry as well as the dollar amount: a shorter recharge may mean more payments across the year. Prices are kept in the table rather than repeated in this guide.
