Traveling to Sri Lanka and not knowing which eSIM service is the best? Learn about different service...
eSIM technology has rapidly gained popularity in recent years, with many tech enthusiasts predicting that it will eventually overtake the physical SIM card.
After all, the benefits are numerous. eSIMs allow for easier switching between carriers without having to swap out physical SIM cards. This is particularly useful for frequent travelers, as it makes it simple to switch to a local network in different countries. eSIMs also free up space in your device, contributing to slimmer, more compact devices.
In this guide, we’ll explain everything you need to know about eSIM technology. We’ll cover how it works, how it compares to a traditional SIM, and how to get started with an eSIM.
An eSIM is a digital SIM that allows you to activate a cellular plan without the need for a physical SIM card. Unlike traditional SIM cards, which are physical chips that you insert into the device, an eSIM is embedded directly into the motherboard. It’s rewritable and can store multiple carrier profiles, making it incredibly flexible and convenient.
eSIM technology works in a similar way to a physical SIM card, but there are still quite a few differences.
The main difference between eSIM and SIM lies in how they are physically implemented. A traditional SIM card is a physical piece of plastic that you insert into a tray on your phone or device. However, an eSIM is digital, embedded in the device’s hardware. It doesn’t require a physical card to function.
This fundamental difference brings with it several other distinctions:
| Feature | SIM Card | eSIM |
| Physical Form | Physical, removable card | Embedded within the device |
| Activation | Requires inserting a physical SIM card into the device | Activated digitally without physical SIM |
| Switching carriers | Requires swapping SIM cards | Can switch digitally without removing anything |
| Device compatibility | Works with all phones and other devices that have physical SIM slots | Works only with devices that support eSIM (e.g. newer iPhones, some Android devices) |
| Multiple profiles | One SIM card can store only one profile at a time | Can store multiple carrier profiles simultaneously |
| Setup process | Manual insertion and swapping SIM cards | Instant activation via software settings or QR code scanning |
| Space usage | Takes up physical space in the device | Does not require physical space |
eSIM works by embedding a programmable SIM chip directly into your device, eliminating the need for a physical SIM card. Instead of swapping out SIM cards, you can activate an eSIM digitally by scanning a QR code, entering carrier details manually, or using your carrier’s app.
Once activated, the eSIM connects to your carrier’s network just like a traditional SIM card. You can store multiple eSIM profiles on a single device, allowing you to switch between different carriers or plans without changing physical SIMs.
eSIM technology offers flexibility and convenience, making it beneficial in various scenarios. Here are the main uses cases:
Like any technology, eSIMs have pros and cons. Here’s a quick breakdown:
| Pros | Cons |
| No need for a physical SIM card | Not all devices support eSIM |
| Easily switch between carriers | Some carriers don’t offer eSIM plans |
| Store multiple eSIM profiles on one device | Requires internet access for activation |
| More secure (can’t be physically removed) | Not all eSIMs support voice calls and SMS |
| Eco-friendly (reduces plastic waste) | Troubleshooting can be more complex than with a physical SIM |
| Ideal for international travel | Some providers charge extra fees for eSIM activation |
So, while eSIM technology is a great option for users seeking convenience, security, and flexibility, users need to check device and carrier compatibility before making the switch.
Getting an eSIM is a simple process, but the steps may vary depending on your carrier and device. Here’s how you can get an eSIM.
Before getting an eSIM, always check if your device is eSIM-compatible and whether your carrier supports eSIM activation.
Using an eSIM is straightforward, but the process can vary depending on your device and carrier. Below, we’ll cover how to set up, activate, and deactivate an eSIM on your phone.
Follow these steps to set up the eSIM profile on your device.
On iPhone:
On Android:
The exact instructions may vary based on your device.
Most carriers activate eSIMs automatically after the profile is downloaded. But, in some cases, you’ll need to do it manually with detailed instructions on how to activate eSIM.
With international eSIMs, your plan will often activate automatically when you arrive at your destination. Make sure your data roaming is switched on so that you can connect to the local network.
If you need to disable your eSIM temporarily or remove it permanently, follow these steps.
On iPhone:
On Android:
Make sure to follow your carrier’s instructions to disable the line so that you don’t incur any accidental charges.
No, not all phones support eSIM technology. While eSIM adoption is growing, only certain models (mostly released from 2018 onward) are compatible with it.
Most flagship smartphones from brands like Apple, Samsung, Google, and Huawei now include eSIM functionality. However, budget and older devices may still rely on traditional physical SIM cards.
It’s important to check your device is on the list of eSIM-compatible phones before you purchase a plan.
Yes. eSIMs can be used on some tablets, smartwatches, laptops, and even some IoT devices. Of course, the model must support eSIM technology.
Here are some options:
eSIM provides seamless connectivity with all of these devices, meaning you can get data anywhere.
eSIM technology comes in different types, each catering to specific needs and use cases.
Yes, eSIMs are generally safe and even offer some security advantages over traditional SIM cards. Since they are embedded directly into your device, they cannot be physically removed or swapped, reducing the risk of SIM card theft or fraud.
They’re generally secure due to:
There are still some concerns, though, including device dependency. If your phone is lost or stolen, recovering your number can be challenging. Also, there is still some vulnerability around the carrier - if there’s a hack, the system is still vulnerable.
Overall, eSIMs are safer than physical SIM cards, but like any tech, they’re not 100% foolproof.
There are many eSIM providers available, each catering to different needs, whether it’s international travel, long-term plans, or regional connectivity. Below are some of the best options:
Each provider has its own strengths, so choosing the right one depends on where you’re going, your data needs, and your budget.
eSIM technology is revolutionizing the way we stay connected, offering a digital alternative to traditional SIM cards. It provides greater convenience, flexibility, and security, making it an excellent choice for travelers, remote workers, and everyday users.
Not all phones support eSIM, but most newer models do. Other devices like tablets and smartwatches may also support eSIM technology.
Where possible, many users are making the switch because eSIMs are secure and reliable. Plus, there are many eSIM providers to choose from, which means there is most likely one around that suits your needs and preferences.
Whether you need a seamless travel connection or a reliable mobile plan, eSIM offers a modern, hassle-free solution.
