Why eSIMs Are Great for Travel

eSIMs, the digital counterpart to traditional SIM cards, are becoming a staple in modern smartphones. The technology is especially beneficial for travellers as international eSIM data plans have become cost-effective and dependable.

eSIMs are a cheaper alternative to global roaming. And if you’re only travelling overseas for a short time – or going to different countries – they’re much more convenient than buying a physical SIM at your destination and swapping it into your phone’s SIM card slot.

What is an eSIM?

An eSIM – short for “embedded SIM” – is a digital version of the physical SIM card. It works exactly the same as a regular SIM card, but instead of inserting it, the eSIM can be downloaded directly to your phone.

With an eSIM, you can set up a new mobile or data plan directly on your device from anywhere in the world. This instant activation process, which can be done before you leave, greatly simplifies the travelling experience.

There are many current providers of eSIMs tailored to travel, such as Airalo, Nomad and Flexiroam.

Why you should get an eSIM

Flexibility

eSIMs are downloadable, and work with an existing SIM card. This works especially well for those who are expecting an important call to their usual number, as you can have both your usual SIM and eSIM active at the same time.

eSIM providers often have various plans that are tailored to different types of travellers with different lengths, data caps and country coverage.

With Airalo, for example, you can choose a plan for a specific country, a region or even a global plan covering every country where Airalo operates. Prices start from around USD4.50 (~AU$7) for 1GB of data lasting 7 days, depending on the country, with better pricing for larger plans.

If you would traditionally use a portable WiFi device, an eSIM could be better suited as well. Your phone can act as a personal hotspot, providing you with constant connectivity for all your devices.

While this does mean you are dependent on your phone battery, many travellers carry a portable charging device to extend their phone’s battery life.

Cost savings

Traditional international roaming charges can be sky-high, even with the day passes offered by major Australian telcos. Likewise, the process of buying a local SIM card in a new country can be both time-consuming and difficult.

Below is a comparison of international roaming passes offered by Telstra and Optus, and eSIM providers Airalo and Nomad. The prices are based on a 30-day trip to the United Kingdom, choosing the highest available data limit:

ProviderCostDataCallsTexts
Telstra$30030GB (1GB per day)UnlimitedUnlimited
Optus$150150GB (5GB per day)UnlimitedUnlimited
AiraloUSD36 (~AU$55)20GBNot includedNot included
NomadUSD30 (~AU$46)20GBNot includedNot included

While Airalo, Nomad and other providers offer data only, you will still be able to receive calls and texts to your Australian phone number. You are also able to use Voice over Internet Protocol (VoIP) services such as WhatsApp with only data, and you can still make phone calls over data using a service like Skype.

In most cases, an eSIM works out to be a lot cheaper. The only exception would be if you’re an extremely heavy data user. But most travellers would only need to use a relatively small amounts of data while out and about, as you can get free WiFi in hotels, airports and many other places.

How to get an eSIM

You will first need to ensure your phone is eSIM-compatible. The Airalo website has a list of compatible devices. Then, choose an eSIM provider and plan, purchase it, and set up an account.

If purchasing an eSIM, you may wish to consider paying with a card without foreign transaction fees, as most providers are based outside Australia.

Install the eSIM following the provider’s instructions, typically by scanning a QR code. Activate the it using the provider’s app and set your phone’s cellular settings to define the eSIM’s use.

Once activated, you can use your phone as usual. Regularly monitor your data usage via the provider’s app to make the most of your plan.

Conclusion

eSIM technology significantly simplifies the traveling experience by eliminating the need for physical SIM card changes, allows for flexibility depending on your travel patterns, and is generally cheaper. They’re here to stay, and are already a valuable tool in a traveller’s repertoire.

It’s been on my “To Do“ list to start this sort of thread but covid got in the way and I find my Optus package (with included roaming data) generally does the job. But prior to switching to Optus i specifically bought a new iPhone with dual SIM (physical + eSIM).

I used TruPhone in Sth Africa on a data package - which worked well. I have some pricing info I‘ll upload.

Initially, the local Telcos weren’t doing eSims, so you either had to do the physical sim swap or find a suitable eSIM service provider. They’re all doing eSims now, so one option is to put your primary (local) number on the eSIM and free up the physical slot for local sims you pickup along the way.

*BUT* the advantage of eSims is you can get them before you leave the country or even swap over - without needing to go into s physical store etc.

If your using iPhone, here’s some info:

I suspect some people don’t even realise they have a dual sim phone because the esim options in settings don’t appear until you load one.

Click through on the page above shows “eSIM carriers”:

If you rock up to one of those countries, you’re supposed to be able to purchase some service and scan a QR code to load up the eSIM.

If you’re just after roaming data, TruePhone, Flexiroam (and others) have packages / bundles. They come with an app to manage the eSIM and packages.

So if I want to sign up for an overseas eSIM, where does the QR code come from? The providers website when I sign up?

I believe so. I’ve never actually done it via QR code - hopefully someone who has can share their experience.

I’ve been using Airalo over the past few years and have had great experiences across the EU and North America. So long as you only need data then they’re quick and easy to setup.
They also have regional plans that can cover more than one country.

The only hiccup has been in PNG however their customer service was quick to deal with the issues with the local network provider.

Have my Australian telco on an eSIM and I use a physical sim when overseas. Works a great for receiving texts to my Australian number and any urgent calls.

I usually pre purchase sims for overseas from simsdirect.com.au

Have done it a few times and would recommend them.

I figure it’s easier to have an eSIM Australian number and foreign physical sim, rather than the other way around. I usually pop the physical sim into my phone in the lounge before departing Australia.

Wow this looks incredible. Thanks for pointing it out. If only it included voice & text it would be even better, but still might work well combined with Whatsapp/Skype.

Edit: It looks like Truphone does something similar and their prices are the same and occasionally even better than Airalo.

I haven't used an international esim just yet, but I'm going to this week. I tried out an optus esim just to see if it would work as expected (and abused the 7GB for the first free week :).

The process itself was amazingly simple. I can turn the sim on and off very easily. I was actually very impressed at how easy it all was to use, and did not impact my existing physical sim at all.

I would warn you that using 2 sims will drain your battery faster. The two radio receivers work simultaneously, and that uses power.

TruPhone will charge in AUD (if you pre-purchase in Oz). Otherwise the local currency if it supports that. USD the default but GBP, EUR and some others (where TruPhone is listed in the carrier list in my earlier post I believe they have a local currency agreement).

Prior to going and while overseas I checked the going rates from TruPhone. Here’s the UK/EU pricing in $Oz before I left.

Same from Singapore (USD).

Then in the UK (GBP).
