Telstra are launching their eSIM support from Thursday, with a free offer of 30GB to use within 30 days to kick things off - however it's only supported on Windows 10 devices which have an eSIM (like the 2017 Surface Pro with LTE)
From March 7 to December 31, for anyone that wants to try out the new technology for themselves, we’re offering customers who have a compatible Microsoft eSIM-enabled device a 30-day trial that includes 30GB of free data to use in Australia. Once the trial period or data has expired, customers will be able to choose a variety of prepaid or post-paid offers from our range of plans.

eSIM technology is currently already available on some Windows 10 devices including the Microsoft Surface Pro 4G LTE and premium HP Spectre range – the HP Spectre Folio 4G LTE and the HP Spectre x360 4G LTE – and will become more prevalent with a number of new Windows based devices already slated for launch through 2019.
Just to clarify, eSIM has been available on Apple devices, like the Apple Watch, with Telstra for over a year now. It’s just that they’re launching it with Windows 10, which is why this promotion is only limited to those devices.
