That's true, even Telstra was slow getting to it (was only available for prepaid services for a long while). I think Aussie telcos need a bit of kick to really go in on eSIM, such as Apple releasing eSIM only iPhone's in the USA. You can't even get a add-on SIM for an Apple/Android Smartwatch from anyone except the big three here still.

It would be good to have regulation surrounding eSIM, because telcos will always find a way to make it awful. E.g. able to do 24x7, max 1hr processing time, no cost to user, able to do via self-service options.

I have a Telstra prepaid esim.
