read about the news on March 2019, haven’t tried it until talked on Live Chat, some staff still insist it is for Apple Watch only. Fact: as a post-paid customer with latest iPhone (Xs/Xs Max/Xr) you can go in Optus stores to ask for QR card, they can help you set up :). Gaming changing for dual sim users :), no more 2 phones 2 hands lol
From Optus website:
eSIM is available to existing, new or recontracting Postpaid Mobile customers with an iPhone XS, XS Max and XR, running iOS 12.2 or later.
Can I activate an eSIM and still use my original SIM (a la the old days of the $5 data sharing sim - of which i still have 3)?
