What is a Telstra eSIM, and how does it work?
Telstra offers one of Australia’s SIM card options, and its eSIM is simply the digital version of a physical card. Rather than fiddling with a tiny plastic tray and hoping you don’t lose the ejector pin, you download the Telstra service straight to a compatible device, typically through the My Telstra app or by scanning a QR code.
So, what’s the upside to using a Telstra eSIM? For starters, activation tends to be faster since there’s nothing to physically ship or slot in. If your phone supports dual SIM functionality, you can run two numbers on one device, which is handy if you want a local Australian number alongside your home line. And yes, there’s the environmental angle too — no plastic card, no packaging.
It also helps that Telstra is one of Australia’s “Big Three” carriers (alongside Optus and Vodafone) and runs the country’s largest mobile network, with over 2,000 more mobile sites than any other Australian carrier. That’s a real advantage if you want your coverage to include anything beyond the big cities — regional and remote coverage is where Telstra tends to pull ahead.
More broadly, eSIMs are now a standard feature with carriers worldwide, which makes it far easier to switch providers or add a travel line without swapping cards every time you cross a border. And if your travels go beyond Australia, Saily is worth a look — it offers affordable mobile data plans in 200+ destinations, so you can get online abroad without hunting for a SIM shop the moment you land.
How do I get a Telstra eSIM?
You have two main paths to get a Telstra eSIM — starting a brand-new Telstra plan using an eSIM or switching an existing physical SIM over to a digital one.
If you’re setting up a new plan, you can grab an eligible Telstra plan online or through the My Telstra app and activate it as an eSIM. Depending on the method, you’ll either follow an in-app setup flow, scan a QR code, or use carrier activation, where your device detects the eSIM automatically during setup and prompts you to download it with a 6-digit confirmation code Telstra sends you.And if you’re already a Telstra customer, switching from a physical SIM is pretty painless. Log in to the My Telstra app, head to "Services," select your mobile service, tap “Set up or manage eSIM,” and follow the prompts to convert. No plan change required — it’s the same service, just a different SIM format.
In most cases, activation only takes a few minutes. It’s a good idea to stay connected to Wi-Fi while performing this action, since your mobile service can briefly drop during the switch. And if you’d rather have a human in the loop than trust the app gods, Telstra also offers help in its retail stores. Just make sure your phone supports eSIM technology!
Can tourists buy a Telstra eSIM?
Tourists can absolutely buy a Telstra eSIM, and a prepaid plan is usually the way to go. Telstra’s prepaid eSIM plans are available for purchase online, and you can activate one after you arrive in Australia as long as you’ve got a compatible device.The one hoop you’ll need to jump through is identity verification. Australian law requires ID checks before activating any prepaid mobile service, but you don’t need to be a resident — an international passport is accepted as valid ID for prepaid activation. For travelers who want something simpler with no ID checks, dedicated travel eSIM providers like Saily tend to offer a smoother experience. Just download the Saily eSIM app, get a plan suitable for your needs, and connect!
Telstra eSIM plans in 2026
One thing worth knowing up front — Telstra doesn’t have special “eSIM plans.” Every plan that works with a physical SIM also works with an eSIM, so it’s just a different format, not a different product. In practice, you’re choosing a Telstra plan, then deciding how you want to activate it.
As of September 2026, here’s what Telstra offers:

Telstra tweaks plan pricing and inclusions fairly regularly — the most recent round of changes took effect on May 5, 2026 — so it’s worth double-checking current rates on Telstra’s website before committing.
How to transfer Telstra eSIM to a new phone
Treated yourself to a new phone mid-trip? Don't worry — moving your eSIM across is simple. Switching phones with an eSIM isn’t quite the same as swapping a plastic card from one tray to another — your eSIM profile exists digitally on the device, so you need to transfer or re-download it to the new one.
Here’s how to do it in the My Telstra app:
Check that your new phone supports eSIM technology and is connected to Wi-Fi.
Open the My Telstra app on the new device and sign in.
Go to “Services” and select “Set up or manage eSIM.”
Tap “Transfer or restore eSIM” and follow the prompts.
If you’re moving between two iPhones (or two iPads), Apple’s “eSIM quick transfer” can speed things up. With both devices nearby, you go to “Settings,” tap “Mobile,” and then “Set up mobile” on the new phone, choose the service you want to transfer, confirm, then approve on the old device when prompted. You’ll need to verify your identity and download the eSIM profile to finish. It’s a nice shortcut when it works — just don’t count on it for every scenario.
One big warning — don’t factory reset, wipe, or trade in your old phone before the transfer is done. If you erase the eSIM profile before the new device is activated, recovering it becomes a much less enjoyable way to spend your afternoon. You can always remove the eSIM profile from the old device after the new one is up and running.
And if you hit a wall with the self-service path, Telstra support is available via phone, chat, or in-store. Sometimes the fastest fix is just letting someone else take charge.
Can I use Telstra eSIM overseas?
Using your Telstra eSIM internationally is possible, but whether it actually makes sense depends on your plan type, your destination, and how long you’ll be away.
If you’re on a postpaid upfront plan, you get access to Telstra’s International Day Pass, which covers a solid list of countries across three zones:
Zone 1 — AU$5/day in New Zealand, Fiji, Papua New Guinea, Samoa, Tonga, Vanuatu, and Nauru
Zone 2 — AU$10/day across most of Europe, the Americas, Asia, and parts of Africa and the Middle East
Zone 3 — AU$10/day in a handful of additional destinations (available on upfront plans only)
Zone 1 and Zone 2 passes include 2GB of data per day plus unlimited standard calls and SMS. If you burn through the data, a 2GB top-up costs an extra AU$10 and lasts 31 days. That’s convenient for a long weekend, but the math gets less friendly on longer trips. Two weeks at AU$10 a day adds up to AU$140 just for the privilege of roaming — and that’s before any data top-ups. A month-long trip? You’re looking at more than AU$300 in extra roaming charges!
Telstra does offer prepaid international roaming packages in some destinations too, but coverage is narrower and it’s not the kind of seamless, automatic roaming you get with a day pass on postpaid. If your destination isn’t on the eligible list, you’re out of luck unless you connect to Wi-Fi or grab a local SIM.
For many travelers, the smarter move is to keep your Telstra eSIM active for your Australian number — incoming calls, texts, two-factor authentication codes — and add a second eSIM from a travel-focused provider for data. Most recently released phone models support dual SIM functionality, which makes this easy in practice.
In such a situation, a service like Saily can save you real money. Instead of paying Telstra’s daily roaming fees, you pick up a destination-specific data plan at a fraction of the cost, and your Telstra line remains available for use. A Saily eSIM is not a replacement for your Telstra service — it’s more like a travel buddy for data.
Alternatives to the Telstra eSIM for travelers in Australia
Telstra isn’t the only option for getting online — and depending on your priorities, it might not even be the best one.
Among local carriers, Optus and Vodafone both offer prepaid eSIM plans with competitive pricing and solid metro coverage. Vodafone is the only major Australian carrier that lets prepaid users keep browsing at throttled speeds after hitting their data cap, which is a nice safety net.
For travelers moving between countries, travel-focused eSIM providers like Saily are built for a different use case entirely. With a travel eSIM, you can activate it in minutes through an app. Such travel eSIM services often offer regional or multi-country plans too — so one eSIM can cover your entire trip rather than just one stop. Saily, for example, covers 200+ destinations and lets you add new plans to the same eSIM without reinstalling anything.
So local-carrier eSIMs are best when you want an Australian phone number and plan to stay in-country. Travel eSIMs are the better pick if you want fast setup, no paperwork, and coverage that follows you across borders.
