What is a travel eSIM?
If you are new to the concept, think of a travel eSIM as a fully digital version of a traditional phone chip. Instead of swapping physical pieces of plastic, you simply download a digital data plan directly onto your smartphone via an app or a quick QR code scan before you even leave home. It allows you to tap into local networks the second your flight touches down, bypass expensive roaming fees entirely and keep your primary Australian phone number active in the background for important bank verification texts.
Whether you’re planning a multi-country European summer, a quick weekend escape to Bali, or an extended getaway across Asia, finding the right digital setup can save you hundreds of dollars.
The best travel eSIMs for your next overseas trip (2026)
01 Nomad eSIM
Best for value and native AUD pricing
Nomad is one of the most trusted travel eSIM providers globally, and it stacks up particularly well for Aussie travellers. It covers more than 200 destinations worldwide – meaning you can sort your connectivity whether you’re heading to Bali, Barcelona or beyond.
What sets Nomad apart is its combination of competitive pricing, a genuinely good app experience, and 24/7 live customer support. Plans are available by country, region, or globally, and you can top up directly through the app if you run out of data mid-trip – no reinstallation required. Current sale pricing includes deals like 20GB for Europe over 30 days from around AUD $36, and 50GB for Thailand over 10 days from around AUD $20.
Nomad regularly runs sales, so it’s definitely worth checking their deals page before you buy, as limited-time bundles (like their Value Bundle packs with 12-month validity) can offer significant savings for travellers who plan ahead.

Covering over 200 destinations, it takes the absolute guesswork out of locking down a reliable travel eSIM. You simply pull up the app, pick your destination and download your data package in a few taps – saving you from carrier bill shock and that frantic hunt for patchy airport Wi-Fi the second you step off the plane.
Pricing varies depending on your destination, trip length and how much data you need. With starter packs kicking off under $10, it’s an incredibly low-risk, easy option for first-time users, though larger data limits and multi-country zones will naturally cost a bit more.

What we love most is the focus on unlimited data plans, which makes it useful for longer trips or heavy data use like video calls, streaming and hotspot sharing (with daily limits in some destinations). You’ll also keep your WhatsApp number and customer support is available 24/7 if you need help while travelling.

The Australian-founded eSIM provider specialises in unlimited data plans across popular destinations like Europe, Japan, Bali, South East Asia and the USA, with options lasting up to 180 days. Set-up takes just a few minutes, hotspot sharing is supported, and you can even keep your number while travelling.
With regional options for multi-country trips and a money-back guarantee for added peace of mind, it’s the perfect pick for longer holidays or travellers who don’t want to stress about running out of data.

06 Ubigi
Best for easy data top-ups
Picture this: your data cuts out while you’re trying to navigate an unfamiliar city street, but your provider requires you to be on Wi-Fi just to load the app and buy more. It’s a frustrating catch-22 that catches plenty of us off guard. This is exactly where Ubigi shines. Unlike a lot of eSIM brands that lock you out the second your balance hits zero, Ubigi leaves its own app connection open for recharges. You can top up your data anywhere, anytime, without having to hunt down a cafe Wi-Fi network.
It is a fantastic option if you aren’t quite sure how much data you’ll burn through but want a guaranteed safety net against being stranded. Because it offers everything from quick one-offs to recurring monthly and annual plans, it’s also highly popular with corporate travellers and long-term nomads.
Top eSIM deals:
- USA – from AUD $5
- Thailand – from AUD $7
- China – from AUD $7
- Italy – from AUD $7
- South Korea – from AUD $7
07 Roamless
Best for paying for what you need
Most traditional travel eSIMs come with annoying expiration dates: use your data within 7 or 30 days, or lose it forever. Roamless completely throws that rigid rulebook out the window. It operates like a prepaid digital wallet where you load up funds just once, pay dynamically by the megabyte as you browse, and your balance never expires.
But the real game-changer here is something almost no other eSIM provider offers: a built-in voice calling feature. Because 99 per cent of travel eSIMs are strictly data-only, trying to ring a local overseas hotel to check a check-in time or calling a boutique restaurant to change a dinner reservation can be nearly impossible without triggering an expensive roaming bill from your Australian carrier.
Roamless lets you dial real international landlines and mobile numbers directly through the app, making it an incredibly practical option when you’re out and about.
Top eSIM deals:
- USA – from AUD $5.51
- Canada – from AUD $6.90
- Mexico – from AUD $5.51
- UK – from AUD $5.51
- Switzerland – from AUD $5.51
- Spain – from AUD $5.51
The benefits of using a travel eSIM
Travelling abroad comes with enough to think about without adding ‘find a SIM card shop’ to the list. Here’s why more Australians are switching to a travel eSIM before they fly:
Cost effective plans
International roaming through Telstra, Optus or Vodafone can cost anywhere from $5 to $10+ per day. A travel eSIM for the same destination typically works out to a fraction of that – often $1-3 a day for a solid data allowance. Over a two-week trip, that’s a meaningful difference.
Setup takes minutes
You buy your plan online, scan a QR code or tap install in the app, and you’re done. No hunting down a kiosk after a 14-hour flight, no passport copies, no fiddling with a SIM tray tool at the gate.
You can keep your Australian number
This is a big one. Because a travel eSIM runs alongside your regular SIM, you can still receive calls and texts on your usual number while using local data rates abroad. Your family can still reach you. Your work emails still come through. You don’t have to pick one or the other.
Works across multiple countries
Many travel eSIM providers offer regional plans, so if you’re doing a multi-stop Europe trip or island-hopping through Southeast Asia, one eSIM covers the whole journey.
More secure than a physical SIM
An eSIM can’t be lost, stolen or skimmed. If your phone is lost or stolen, there’s no SIM card for anyone to remove and use in another device.
Better for the environment
A travel eSIM is entirely digital from purchase to activation – a small but real sustainability win compared to single-use physical SIMs.
Frequently asked questions:
Is a travel eSIM cheaper than international roaming?
Yes, in most cases significantly so. International roaming through Telstra, Optus or Vodafone can cost $5-10+ per day, whereas travel eSIM plans from providers like the ones mentioned above typically work out to $1-3 per day for a comparable data allowance.
What are the disadvantages of using a travel eSIM?
The main limitations are device compatibility (your phone must be eSIM-capable and carrier-unlocked), and the fact that most travel eSIMs are data-only. They don’t include a local phone number for calls or SMS. You would need to use apps like WhatsApp or FaceTime for voice calls instead.
Which eSIM is best for travelling from Australia to Europe?
For Europe, both Nomad and Saily offer strong regional plans covering the Schengen area and beyond. A regional plan works out considerably cheaper than buying individual country plans – expect to pay around AUD $30-40 for 20GB over 30 days.
Does an eSIM affect data speed or signal strength?
No. An eSIM connects to the same local carrier networks as a physical SIM card would, so your data speeds and signal strength should be equivalent. The main variable is which network the eSIM provider partners with in your destination. Premium providers like Nomad and Sim Local typically partner with the strongest local carriers.
