eSIM TECHNOLOGY: 5 Beneficial Reasons why you Should Activate it!
What have you heard about the eSIM technology? Allow me to make a guess!
Unlike the SIM card you possess, it is not a physical SIM. What you know is correct; however, there is more to it than just “Not a physical SIM” you may have heard or know!
So, what are exactly is eSIM, and how does it reshape the methods used to connect and communicate with mobile networks?
In today’s post, we will explain everything you need to know on the topic of eSIM technology, its advantages, how it functions, and its increasing importance in mobile communication.
Let us share with you all we know about this technology.
What is an eSIM?
eSIM means Embedded SIM. It represents a new era in mobile connectivity. Unlike traditional SIM cards, which are physical, removable, and have to be placed inside your device, eSIM is a digital SIM card that is hard-coded into your device.
A mobile subscriber’s account is identified via a SIM associated with the particular network the subscriber is using. This means the SIM facilitates access to mobile subscription services, e.g., voice and data services.
The only difference about eSIM is that it keeps the mobile network’s profile information in digital form, permitting users to access their carrier’s network without the need for a physical SIM card.
How Does eSIM Work?
eSIM functions by keeping one or more carrier profiles on your device. These profiles can be activated or changed remotely, so you can connect to various networks without needing to change SIM cards.
Typically, an eSIM is activated over the air by scanning a QR code or through a relevant application by your chosen network provider’s app. With the eSIM technology, changing network providers, plans, or activating new services is simplified to just a few taps.
The Benefits of eSIM Technology
* No Physical SIM Cards Required: This is particularly beneficial for people who travel, as they no longer have to carry an additional SIM card with them. All your carrier information is stored securely on your device.
* Increased Convenience: eSIM makes it easier than ever to switch plans with different mobile carriers. For example, you can now change your carrier without having to go to a store to get a SIM card. Everything is done digitally.
* Allows for Dual SIM Functionality: Many eSIM-enabled devices allow for dual SIM capability, meaning you can have an eSIM and a physical SIM card simultaneously. This is especially handy for tourists who have to manage both local and international lines or for separating work phone and personal one’s primary numbers.
* Space Saving During Design: Manufacturers can use the space for the SIM CARD tray to add other components like large batteries, more efficient processors, or better camera systems.
* Eco-Friendly: eSIM is an environmentally friendly option compared to traditional SIM cards, as they don’t require plastic, which reduces waste and the carbon footprint associated with manufacturing and shipping SIM cards.
How can I find out whether or not my device supports eSIM technology?
iPhone: Settings > Cellular or Mobile Data > Add a New Cellular Plan
If the option to add an eSIM is available, that means your phone supports it.
Android: Settings > Network & Internet > Mobile Network
Options for eSIM settings or dual SIM settings should be present.
Dialing #06#:
Using your mobile’s dialer, input *#06#. If the device is compatible an eID (embedded SIM unique identification number) will be displayed on the screen.
What devices can use eSIM technology?
There is a large list of devices that support eSIM technology, such as:
Smartphones: eSIM compatibility can be included within mainstream devices such as iPhone XS, iPhone 11, Google Pixel 3, and Joanna, and Samsung Galaxy Series.
Wearable technology: Currently, Apple Watches, Samsung Galaxy Watches, and other Smart watches use eSIM.
Tablets and laptops: This feature is also available in the iPad Pro (2018 and newer) and some laptops that are 4G/5G capable.
IoT devices: Smart cameras, smart sensors, and other smart products that are connected devices essentially rely on eSIM technology for effortless communication.
How to Activate eSIM
Activating eSIM is quite straightforward. Depending on your carrier, it usually involves the following steps:
1. Getting the Carrier Profile—You must acquire the eSIM profile from the carrier by either scanning a QR code or using an app the carrier has.
2. Activating eSIM—You can enable it through the settings of your device once the profile is acquired. Many times this can be done in a matter of minutes.
3. Switching Between Profiles—If your device accommodates more than one profile, you can switch between carriers easily without having to remove any SIM cards.
Comparing eSIM and Physical SIM Cards
| eSIM vs. | Physical/Traditional SIM |
|---|---|
| An eSIM is built right into your device while having the ability to support several carrier profiles, enabling remote activation and management (which is not possible with SIM cards). | A SIM card is a card that can be put into a device and must be swapped physically, making it less flexible. |
| The issue of damage SIM is completely eradicated | Physical/traditional SIM often gets damaged leading to line Retrieval which is another time consuming process and expenses. |
| It is irremovable but can be transfered from one device to another in case you wish to switch phones/devices | It can be removed at any point of time |
| Not all devices and MNOs (mobile Network Operators) supports the eSIM technology. | All devices with SIM slots supports traditional SIMs |
| May be deactivated | The same |
Why eSIM is more secure than physical SIM cards
The use of an eSIM offers additional saftey features. A profile kept on an eSIM is encrypted and stored within a device making it safer than a standard SIM. Masters of the device can with ease enable or disable profiles through secure commands.
Another security feature I like about this eSIM technology is that you can lock it with your preferred PIN code and no one else will be able to unlock it except you. This feature helps in the case of a stolen phone.
If you have the SIM-PIN feature enabled on your embedded SIM, be rest assured that your profile wouldn’t be tempered with.
Carrier Support for eSIM
While major carriers around the world are embracing eSIM, its adoption is still growing. Countries like the United States, United Kingdom, and many European countries have widespread eSIM availability.
However, not all mobile networks or regions offer eSIM support yet. In Nigeria, I think it’s only MTN and Airtel that support the eSIM technology. However, as the technology becomes more common, expect more carriers to integrate it into their plans.
is eSIM Right for You?
The adoption of eSIM is growing, and it offers incredible convenience for users who want flexibility and ease when managing their mobile network connections. eSIM might be the right choice for you if you are:
A Frequent Travelers: eSIM allows you to switch between international and local networks easily, eliminating expensive roaming fees.
A Tech Enthusiasts: Those who enjoy exploring the latest in mobile technology will appreciate eSIM’s streamlined, future-proof approach.
A Business Owner and Professional: Managing multiple lines or separating work and personal numbers is easier with eSIM technology.
An Environmentally Conscious User: If reducing your environmental impact is important to you, eSIM’s reduction in physical SIM card waste is a significant benefit.
