How to Register and Activate Your Optus SIM?


To register and activate your Optus SIM, visit optus.com.au/activate, enter your SIM number, provide your personal details and valid ID, select a plan, and follow the prompts to complete activation. Activation can be done online using a computer, tablet, or another phone, and you’ll need a current ID such as a driver’s licence, credit card, or passport. Once activated, insert the SIM into your device and you’re ready to use your Optus service.

Optus makes SIM activation straightforward and accessible. Whether you’re a new or existing customer, you can activate your Optus SIM card online at optus.com.au/activate using any device with internet access. The process requires your SIM card number, personal details, and valid identification. You’ll also choose a prepaid plan during activation, and you can opt to recharge immediately or later. The online portal is user-friendly and supports both Australian and international customers, making it easy to get connected quickly.

Steps to Register and Activate Your Optus SIM

  • Your new Optus SIM card (with SIM number).
