A lower-case ‘e’ is a powerful prefix. It’s heralded the shift from physical mail to digital email and paperback books to electronic libraries for ereaders. Even the popularity of real-world sports has been matched by the rapid rise of esports. And now the physical SIM card is under threat from the eSIM.

What is an eSIM?

An eSIM is a digital SIM card. In terms of the physical SIM vs eSIM debate, the former is a card that must be correctly inserted into your phone before you can use a smartphone’s cellular capabilities, while the latter doesn’t have a physical component. To configure an eSIM, you usually download an app or scan a QR code.

Outside of not having to physically insert or remove a SIM card, the big benefit of an eSIM is that you can technically shift telcos instantly, as long as the new mobile provider supports eSIMs. This effectively eliminates downtime between plan swaps.

The other benefit of an eSIM is it frees your smartphone’s physical SIM card slot for another SIM, converting your phone into a makeshift dual-SIM handset.

Finally, eSIMs also let you share the same mobile number between a smartphone and compatible smartwatches, including the Apple Watch and certain Samsung smartwatches.

Before we start, here's a quick look at some of the most popular eSIM-compatible mobile plans in Australia.

Which telcos offer eSIMs in Australia?

Even though eSIM might still seem like such a futuristic concept, more providers have adopted the technology than you might expect. At the time of updating this guide, there are 18 Australian mobile providers who offer eSIM:

Telstra
Optus
Vodafone
Amaysim
Boost Mobile
Circles.Life
Everyday Mobile from Woolworths
Exetel
Felix
iiNet
Kogan Mobile
Lebara
More Telecom
Spintel
Superloop
Tangerine
Yomojo

It's worth adding that the three big telcos offer different levels of support for eSIMs. For instance, Optus supports eSIMs for compatible smartphones and wearables. Vodafone also supports these devices but adds tablets to the mix, while Telstra supports all three alongside compatible Windows PCs. If you’re eager to travel with an eSIM, you can look into providers like Airalo.
