While there are some differences between the duo, many of those differences aren’t as big as you might think. Here’s the low down on what an eSIM is, what devices support eSIM, which Telstra and Optus postpaid and prepaid plans are available on eSIM and how to set up eSIM with either of Australia biggest mobile providers. Telstra puts the responsibility back on you to ensure you have a device with an “eSIM symbol” to confirm its eSIM compatibility. That’s not overly helpful, Telstra. Thankfully, Optus offers a list of eSIM-compatible devices to use as a guide: If you’re with a mobile provider (like Optus or Telstra) that offers eSIM connectivity, swapping out your physical SIM card for an electronic one can be done online via an app, over the phone or in-person at a physical store. The second benefit that eSIM offers is that it can effectively turn a single SIM handset into a dual-SIM. Swapping to eSIM will free up the physical card slot inside your device. What happens next is up to you. Last but not least, eSIM also offers benefits to those using wearables like the Apple Watch as it allows you to share the same mobile number across both your smartphone and select smartwatches.
