An eSIM is an electronic SIM card that offers a digital alternative to a traditional physical SIM card. Instead of physically switching out a SIM card, eSIMs can be downloaded onto your phone and activated through your phone's settings. eSIMs also allow you to use multiple SIM cards at once, so you can access multiple phone numbers (like a work and a personal number) or have access to your regular number but use the data from an eSIM while travelling.
eSIMs are becoming increasingly popular, with many telcos now offering the option on their phone plans. eSIMs are also particularly useful for travelers because they make it easy to switch between networks without having to physically change SIM cards. Beyond travel, eSIMs are also a great everyday option, because they allow you to more easily switch mobile providers without the hassle of purchasing a physical SIM in store, or waiting for one to be delivered.
If you’ve got a trip planned, it’s worth looking into eSIM options from dedicated international eSIM providers so you can easily access data while overseas without spending a crazy amount of money on international roaming fees. While some Australian providers offer international roaming for as little as $5 per day, if you’re planning on travelling for more than a few days, this can add up and it’s often cheaper to opt for an international eSIM.
If you’re not sure where to start looking for a good value international eSIM, we’ve rounded up some of the best and most popular providers below, including four digital telcos that offer free eSIM trials with up to 600MB for 30 days for free before you commit to buying.

Other popular global eSIM providers
While a free trial is a great option for testing an eSIM provider, it probably shouldn’t be your only criteria when it comes to finding the best eSIM plan to fit your needs. In fact, many of the most popular global providers don’t offer trials, although most have lower-priced plans that can be an effective method for trialling whether they’re worth continuing with.

FAQs
How do you activate an eSIM?
There are actually multiple ways to set up an eSIM, so the exact steps can be different depending on the provider. Generally speaking, there will be an app you can download, an email with a QR code, or a set of step-by-step instructions to follow. You’ll also need to make sure you have a data connection (just Wi-Fi will work) during the activation process because you will need the internet.
When should I activate my eSIM?
If you’re purchasing an eSIM for travel, unless the provider specifies otherwise, you should wait until you arrive at your destination before activating. Activating beforehand may cause you to use some of the included days as the plan usually starts from the moment of activation.
What phones do eSIMS work in?
Most newer smartphones should be eSIM compatible. For iPhones, all models starting from the iPhone XS (released in 2018) can use eSIMs and all Samsung phones released since 2020 should be eSIM compatible. You can also look up your specific device on the manufacturer’s website, or check within your device’s settings to see if it's compatible with eSIM.
Do eSIMs have phone numbers?
Some eSIM plans do come with a local phone number and some credit to make calls and send texts; however many travel eSIMs are data-only. If you need an eSIM that comes with a localised number, make sure you check with the provider before purchasing.
Do eSIMs work on cruise ships?
Whether an eSIM works on a cruise ship will depend on the region it’s designed for, as well as whether there is reception on the cruise ship. Some eSIM providers like GigSky and Airalo offer data plans specifically for cruise travel, so if you’re going on a cruise, choosing one of these specialised plans can help ensure you stay connected while at sea.
