I have lost my sim its on a plan, can I get a replacement sim with my number on it ?
I'd check if there's an Optus retail store open near by. You can pick up a SIM and we'll replace it on the spot (with your number of course)
Otherwise, you can message us via the My Optus app. We'll send a SIM out and you can activate it via our online activation portal.
