At the majority of flagship smartphone launch events in 2024 and 2025, you may have seen brands touting eSIM support as one of the major feature highlights. If you're asking yourself what an eSIM is or if you've got an eSIM-enabled smartphone and want to try it out you've come to the right place. In this step-by-step guide, we'll look at what eSIMs are, how they operate, how to configure them, and even present you with new services such as Saily eSIM that can enhance your connectivity experience.
What is an eSIM?
An eSIM, or embedded SIM, is a virtual SIM card permanently embedded within a device. In contrast to physical, removable SIM cards found in standard devices, eSIMs are integrated into the smartphone's motherboard. This feature enables you to turn on a mobile or cellular plan without having to insert a physical SIM card.
How Does an eSIM Work?
An eSIM works just like a regular SIM card but without the inconvenience of physically changing cards. Rather, the SIM chip is built-in to your smartphone's hardware, ready to be activated. Your carrier sends a QR code or an activation code filled with all the necessary information to connect your phone to their network. When you scan this QR code, your phone downloads the required network information directly onto the eSIM instantly, and voilà, you're online! And because everything is digital, you can have several eSIM profiles stored and switch between them with ease, which makes it a great option for travelers or anyone juggling work and personal numbers on the same device.
Key Benefits of Using an eSIM
Let's start with why eSIMs are becoming popular and why you would want to switch:
1. Convenience and Versatility
Swapping carriers and phone numbers has never been more convenient — there's no carrying around multiple SIM cards. A perfect feature for individuals who have to travel much or have professional and personal usage with different phone numbers.
2. Space-Conscious Technology
By removing the physical SIM card tray, phone makers can utilize that extra space to enhance other hardware features such as larger batteries or improved camera systems.
3. Eco-Friendly
The manufacturing of plastic SIM cards and ejector tools generates e-waste. eSIMs abolish this, minimizing the carbon footprint of conventional SIM cards.
4. End of Roaming Charges
Because eSIMs automatically connect to local networks in other areas, you can skip pricey international roaming charges — assuming your carrier allows it.
5. Adjustable Data Plans
eSIM carriers tend to have more flexible, adjustable data plans than the usual SIM card plans.
6. Keep Your Number
Change carriers without altering your phone number, ideal for people who don't want to go through the inconvenience of updating contacts.
Is Your Device Ready?
eSIM has been around for some time now, but not all smartphones support it yet. It is currently available in most flagship phones like Apple iPhones, Samsung Galaxy S and Fold series, Google Pixel, and some OnePlus phones. Most mid-range phones from other brands like OPPO, Xiaomi, and Vivo do not have eSIM yet, although this could change as the technology gains popularity.
It's also worth noting that eSIM compatibility may differ based on your country and mobile network provider. To find out if your phone has eSIM support, begin by going to your phone's official product page. Check the "Connectivity" entry in the list of specs if eSIM is not listed there, contact your phone manufacturer's customer support for confirmation.
