Activate or replace your SIM card

If you need to activate a replacement or a new SIM card, all the information you need is below.

If you purchased online, or over the phone, your SIM should auto-activate within 4 hours of delivery. Periodically turn your device off and on until your SIM has activated. You will see Optus next to the coverage bars once the SIM is active.

Otherwise, follow the prompts at Activate or Replace your SIM.

While you wait for your new SIM to be activated:

  • Insert your new SIM card into your device
  • Change your new SIM card PIN from the default (0000)
  • For mobile devices including tablets, download the My Optus app to manage your account
  • If you have a USB modem, connect it to your computer and install the connection software. See Device Guides for help.

If you’re experiencing issues, go to SIM replacement & activation help.
