eSIM Technology Explained: How It Works & Why It’s the Future of Connectivity
No more fumbling with tiny SIM cards ever again. No more hunting for that little pin to eject your tray or losing your card. What if your phone could change networks, add more lines, or even roam internationally with a few taps?
The world of eSIM technology makes this possible. In fact, by 2027, there will be more than 3.4 billion devices using eSIM, and your smartphone could be one of them.
However, you might be thinking what is an eSIM, how does eSIM work? What’s the buzz around it? So, let’s break it down and find out why this virtual SIM card might be the game changer that you didn’t know you needed!
What is an eSIM?
What if your SIM card could never be popped out of your phone but was still able to operate? The magic of an eSIM is a small chip that’s embedded right inside your phone, tablet, or other device. So how does it work and what is it different from the regular physical SIM card?
An eSIM is a digital version of your physical SIM card and is built into your device’s motherboard instead of being a removable card. It also means no more losing or damaging SIM cards. It is as simple as activating it remotely with your carrier, and it’s the most flexible and convenient.
eSIMs work a little differently than other SIMs, which need you to insert a physical card with a particular network; instead, eSIMs are built into a built-in eUICC (Embedded Universal Integrated Circuit Card) chip. With this, you can activate your phone remotely for multiple carriers and networks without the need for a new SIM card. And you can switch networks, activate new plans or even international eSIMs.
How Does eSIM Work?
Over 20 million eSIM-capable devices were activated globally in 2023, and that number is expected to grow exponentially, eSIM is changing how we stay connected, assets, and simple. How does esim work? Let’s break it down.
The eSIM (Embedded SIM) is not a physical card but a digital profile ‘embedded’ inside your device. The eSIM allows you to change it remotely instead of swapping out a physical SIM card when switching networks or carriers. Here's how it works:
eSIM profiles are activated remotely by your carrier and don’t require a physical card. When you sign up for a plan or switch carriers, they just send a network profile to your phone or device.
Remote provisioning: One of the coolest features of eSIM is that you can change carriers or update your plan without having to get a new SIM card. Simply adjust your phone’s settings, and you can switch networks in seconds without having to pop in a new card.
Multiple Profiles: eSIM enables you to carry multiple network profiles at the same time. This is great for people who travel internationally or those who need to switch between personal and business lines. Multiple carriers can be on one device!
eSIM Standardization: eSIM runs under the eUICC (Embedded Universal Integrated Circuit Card) standard, which means eSIM is compatible with all devices all over the world, eliminating network restrictions when travelling.
If you are wondering how does eSIM works, let us tell you that they work in a similar way to traditional SIM cards, connecting the device to networks to give your device mobile service. But all of it is digital, so there’s no need for a physical SIM card slot, which makes your phone thinner and more durable.
Simply put, the eSIM gives you flexibility, convenience, and the ability to stay connected across networks with just a few taps on your phone.
eSIM Activation Process
By 2025, it is expected that more than 1.3 billion eSIM enabled devices will be in use, and eSIM technology is changing the way we connect, especially for those who are on the move. SIM cards are a thing of the past, and you can now activate your mobile service in just a few steps. We break down the eSIM activation process, and how easy it is to switch and stay connected.
