How They Work, What They Are, and Why They’re a must-have for Travellers
The rise of eSIM technology marks a significant change in the way we use our phones, and holds pivotal benefits for travellers and holidaymakers. As the way we use our electronic devices evolves, the advantages of using an eSIM overseas are clear, making it a game-changer for travellers and those on the road.
Phones and electronic devices have become a necessity in the modern world, with the ability to access maps, translate languages, make payments and convert currency all huge benefits for travellers. However, using your phone abroad without an eSIM can be costly or complicated.
Where traditionally, globe trotters would need to cough up for expensive roaming charges, face poor coverage or purchase a local SIM card, the adoption of eSIM technology means an easier, more flexible way to stay connected while exploring the world.
In recent years, mobile technology has witnessed a significant transformation with the introduction of the eSIM. Short for “embedded SIM,” the eSIM is a digital alternative to the traditional SIM card that offers users a host of benefits. From convenience and flexibility to cost savings and improved efficiency, eSIMs are becoming increasingly popular among travellers and those taking trips overseas.
The promise of great network coverage almost anywhere in the world without steep charges makes the worries of limited connectivity a thing of the past, so embracing the change is a clear winner for anyone on the road.
When choosing an eSIM, understanding what they are, how they work and which one to get is important, and we can help with that.
The promise of great network coverage almost anywhere in the world without steep charges makes the worries of limited connectivity a thing of the past.
How Does an eSIM Work?
The functionality of an eSIM is similar to that of a physical SIM card in that it stores information that connects your device to a mobile network, allowing you to make calls, send texts, and access mobile data. The main difference lies in how the eSIM handles this data and links to the network.
Remote Purchasing
Instead of requiring a physical SIM card from your carrier, the network operator provides you with an eSIM profile. This can then be downloaded over the internet directly to your device, typically by scanning a QR code or inputting a code.
Switching Between Networks
With a physical SIM card, switching carriers or networks typically requires swapping the SIM card, often meaning that you can only use the new local number of the SIM you purchase. Instead, you can now store multiple data plans on a single device and switch between your eSIMs easily in your device’s settings, completely removing the need to purchase a SIM in each country you visit or being unable to access your existing phone number.
Activation Process
Setting up an eSIM is quick and straightforward. Once you receive the activation details from your network provider, usually a QR code, you simply scan it using your device’s camera and the eSIM will be automatically downloaded and activated. Your device will then connect to the network using the eSIM, just as it would with a traditional SIM card.
Multiple eSIMs on a single device
Another majorly beneficial feature is the ability to store multiple eSIMs from different providers. This means that you can store more than one carrier or network plan in your device and switch between them without the hassle of changing physical SIM cards. For example, the iPhone 16 has the ability to store up to eight different eSIMs and use two phone numbers at a time. This feature is particularly useful for travellers who need to switch between different carriers when visiting multiple countries or crossing borders.
eSIM Compatibility: Which Devices Support eSIM?
As eSIM technology has gained popularity, more and more devices are being released with eSIM capabilities. Some of the major devices that support eSIM include:
- Smartphones: Many high-end smartphones now support eSIMs, including models from Apple (iPhone XS, XR, 11 series, 12 series, and later), Google (Pixel 3 and newer), and Samsung (Galaxy S20 and newer). Some of these devices are dual SIM, meaning they support both a physical SIM and an eSIM, allowing users to maintain two active mobile plans at the same time.
- Smartwatches: Several smartwatches, such as the Apple Watch Series 3 and newer, and Samsung Galaxy Watch, support eSIM technology, enabling users to make calls, send texts, and use data without needing a paired smartphone nearby.
- Tablets: Many tablets, like Apple’s iPad Pro and iPad Air models, have incorporated eSIM technology, making it easier for users to connect to mobile data networks without needing to purchase and insert a physical SIM.
- Laptops: Some newer laptops, such as models from Microsoft’s Surface line, also feature eSIM functionality, allowing users to access mobile data on the go and without the need for a Wi-Fi connection. If you’re a digital nomad, this makes working anywhere in the world a whole lot easier.
As more and more devices that support eSIM technology are becoming available, the potential for physical SIM cards to become a thing of the past is looking more and more likely. With most major network carriers now offering eSIMs, travellers can be sure to keep all of their devices connected when on the go.
The Benefits of eSIMs for Travellers
Whether travelling for business or leisure, the challenge of staying connected in a foreign country affects everyone. When overseas, apps such as Maps, Translate and Weather can help to navigate the local environment, whilst the ability to make calls, receive text messages and access social media makes it possible to stay connected to others.
When it comes to the battle of eSIMs vs physical SIMs, there are clear differences to keep in mind. Sticking to your current physical SIM card can result in roaming charges that cause eye-watering expenses and often coverage is still limited in certain areas, whilst buying a physical SIM every time you travel overseas can be time-consuming and result in using a new number, which can be particularly inconvenient for those touring multiple countries at a time. In contrast, an eSIM removes these challenges, making it much easier and more affordable to stay connected during international travel.
Here are some of the key benefits of eSIMs for travellers:
Convenience and Flexibility
One of the biggest advantages of using an eSIM is the convenience it offers. Instead of searching for a local SIM card in a new country, dealing with language barriers, or worrying about whether your phone is compatible with local networks, you can simply download an eSIM profile from a network carrier before or after arriving.
As compatible devices allow you to store multiple eSIM profiles on one device, it is easy to switch between different carriers or data plans, wherever you are. For instance, you could have one profile for your home country and another for the country you’re visiting, switching between them without swapping physical SIM cards. If you keep your primary SIM switched on, you can use your existing phone number whilst using the data from your eSIM.
Cost Savings
International roaming charges can quickly add up, especially if you need to make frequent calls or use a lot of data. With an eSIM, you can avoid these fees by downloading a local carrier’s profile and using their network at local rates. Most eSIM providers offer competitive data packages for short-term or long-term use, making it easier to stay connected without breaking the bank.
Instant Activation
With traditional SIM cards, travellers will need to research local providers, physically visit a store, deal with language barriers and paperwork and can easily end up with a plan that isn’t the best fit for their needs. The process of activating a new SIM for your device can be time-consuming and inconvenient, and if you are travelling to more than one international destination, the process then needs to be repeated in every country you visit.
The instant activation of eSIMs eliminates this hassle by allowing you to download and activate a new plan in minutes. You can purchase an eSIM and set it up online before you travel, or even when you’re already in the country using local Wi-Fi, allowing you to be connected in an instant.
Dual SIM Functionality
Many smartphones with eSIM capabilities also support dual SIM functionality. This means you can have both your existing physical SIM card and an eSIM active simultaneously, which is particularly useful for travellers. You can keep your home SIM active for important calls and texts while using a local eSIM for data. This dual setup allows you to avoid roaming charges while staying reachable on your home number. For digital nomads and those doing business whilst abroad, this means that you can always be contactable and do not need to update clients and colleagues every time you change your physical SIM in each country.
Environmental Benefits
Traditional SIM cards are made of non-biodegradable plastic. When travellers resort to relying on a new SIM card in each country, often for as little as a few days, this collectively adds up to a significant contribution to environmentally damaging waste. An eSIM removes the need for a single-use physical card, eliminating the plastic waste and associated environmental impact of manufacturing and shipping these cards. With millions of physical SIM cards being used by travellers for short periods worldwide, the ecological impact of this is notable. For eco-conscious travellers, choosing an eSIM is a more sustainable option.
How to Get an eSIM for International Travel

Activate the eSIM:
Once you’ve purchased an eSIM plan, you’ll receive a QR code or a unique activation code from the provider. To activate the eSIM on your device, simply scan the QR code using the camera on your phone, or manually input the code into your phone’s settings. This process is simple and typically takes just a few minutes.
Manage Your eSIMs
After activating the eSIM, you can manage it through your phone’s settings. If you have multiple eSIMs activated, you can switch between profiles in an instant, depending on your location and carrier availability. Keep in mind when choosing your eSIM provider the amount of data you are likely to need and monitor your data usage to avoid running out while you are abroad. In many cases, you can even adjust your plan on the go if needed, ensuring that you are never out of connectivity.
Conclusion
The revolutionary development of eSIM technology offers a myriad of benefits for travellers, holidaymakers and those visiting different countries. If you are travelling for business, are a digital nomad or are touring more than one country on your trip, the advantages of using an eSIM also mean that you can easily work on the go without fears that your connectivity will be disrupted or your phone number frequently changed. From convenience and flexibility to cost savings and environmental sustainability, eSIMs provide a significantly better alternative to traditional SIM cards.
As eSIM adoption grows, travellers will enjoy an even smoother experience when staying connected abroad, allowing them to focus more on their journey and less on managing mobile connectivity. However you travel, eSIMs represent the future of hassle-free communication, making it a must-have tool for anyone looking to explore the world without limits.
