As with any month to month plan, you get the flexibility to leave at any time without the worry of running out of credit as you could on a prepaid plan. Use the selector below to find out more about each plan.

  • Unlimited calls don't apply on lower recharges If you recharge My Prepaid Monthly Plus at the $10 or $20 level, you don't get unlimited calls.
  • Shorter recharge period Most monthly plans last for 30 days, but My Prepaid Ultimate expires after only 28 days instead.

Who this plan would suit

Optus' My Prepaid Ultimate plan offers a lot of data with the option to rollover unused data which could be great if you're a heavy data user.

      Hi Sophia,

      The prepaid credit expiry period starts from the moment of activation, not purchase. However, the page you’ve landed on is for postpaid SIM-Only plans. These work on a month-to-month basis and have a set billing period.
