Hi @JohnL ,
Welcome to the community!
Our supplied TPG mobile SIM still not support LTE eSIM for smart watches. There's no update on when the eSIM will be available on our Mobile plan, but once there's an update, it will be posted on our website and social media pages.
I have just received a birthday gift of a Series 6 + Cellular Apple Watch and have now been told TPG does not support this smart watch. Is this really true in this day and age of technology?
