Activate or replace your SIM card

If you need to activate a new SIM or replace your existing SIM, all the information you need is below.

SIM Purchased Online or over the phone

If you received your SIM from an online purchase or over the phone, your SIM will 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 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.

SIM purchased from a Non-Optus store

If you purchased a $2 (12 Month Mobile Plan SIM) from a Non-Optus store, you will need to activate it via optus.com.au/BYOactivate and follow the prompts.

If you need help locating the SIM number or have issues activating, see SIM replacement & activation help.
