Embedded SIM is known as eSIM. eSIM technology, as its name implies, makes it easier to integrate the SIM into wearables and phones. Similar to a regular SIM card, an eSIM functions as a unique identification that enables telecom providers and your contacts to get in touch with you so that you may make calls or send texts. Because eSIMs do not require a physical SIM card slot, they save up space and enable thinner device designs. Compared to regular SIM cards, an eSIM offers higher security since the data on it is encrypted. With eSIMs, physical harm, loss, or theft are less common. This page goes into additional information about the eSIM technology.

eSIM technology: what is it?

Manufacturers and carriers of smartphones have started to adopt a new strategy in recent years: an eSIM has replaced the traditional, physical, removable SIM card. eSIM prevents SIM card theft because there isn’t a physical component to take out and use in another device. Your phone cannot be used by thieves to access your bank or social media accounts once they have stolen it.

How is eSIM technology implemented?

It is significantly simpler to transfer carriers thanks to eSIM technology. By only scanning a QR code, you may enter information from your carrier directly on your phone and complete the change without having to wait for a new SIM card to arrive or go to a store. You may configure your smartphone’s eSIM, swap between lines and carriers, and manage your accounts by going into the settings. The eSIM technology in a dual-SIM smartphone could enable many accounts, and switching between them is easy.

Then, how does eSIM technology function in practice?

The solution is right here: configuring an eSIM is much as placing an online food order. To capture the configuration that will be sent to the virtual card, you must aim the phone’s camera at a 2-D barcode that the operator has provided.

The eSIM card configuration process is finished by going through a series of steps, which vary depending on the phone and whether you use an Android or iOS phone. These steps include choosing whether the eSIM card will be used for calls and data or only for data, and whether the digital SIM will function as a single line or in conjunction with another line, either in another eSIM card or in another phone.

You have to decide which line on your phone to use as the primary and which as the backup if it has several lines. The virtual SIM card may be programmed several times, and it can work with both local and international carriers based on the parameters you give it. With Simbye, you may also activate eSIM and begin utilizing it effectively.

A list of gadgets that use eSIM technology

The following is a list of gadgets that use eSIM technology:

Google Mobile

An eSIM that could only be used with Google Fi was included with the Google Pixel 2. Nevertheless, third-party mobile carriers can be utilized with the Google Pixel 3 and later Pixel devices. Samsung added eSIM technology to its line of high-end smartphones with the Galaxy S20.


Apple introduced eSIM in 2017. Apple still uses a mix of an eSIM and a traditional SIM card in almost all iPhone models. But last year, the iPhone 13 received support for two eSIM cards, giving users dual-SIM functionality without requiring a physical SIM card.

Samsung Mobile Phones

Many of Samsung’s most current phones are eSIM compatible. Up to five virtual SIM cards can be carried by an eSIM, a multi-carrier device that lets you choose between plans via your mobile device’s settings.

With Samsung devices that include an eSIM, you may activate a second cellular data plan that you can use domestically or abroad without a physical SIM card.

Huawei Cellphones

Numerous of the most recent Huawei phones are eSIM-capable gadgets. Without a physical SIM card, Huawei models with an eSIM allow you to activate a second cellular data plan that you may use locally or internationally.

Advantages of the eSIM technology

eSIMs are superior than regular SIM cards in a number of ways. The following is a list of some advantages of eSIM technology:

International Accessibility: An eSIM is recommended if you go overseas regularly. You can always communicate, no matter how often or suddenly you move. The primary goal of an eSIM service is mobile connectivity anytime, wherever.

An eSIM card is never susceptible to loss or damage: One of the many reasons you should test an eSIM is because it can never be lost or destroyed by external conditions. Using an eSIM reduces the risk.

Possibility of having numerous phone numbers: Using an eSIM is similar to using a phone with two SIM card slots in that you may have several phone numbers.

Less space is needed on mobile phones: By eliminating a possible point of failure, the removable SIM card tray may improve the overall robustness of mobile phones.

Simpler to activate: All it takes to activate an eSIM is to scan a QR code, which connects your eSIM profile to your mobile network.

The eSIM technology’s future

It is anticipated that by 2025, over 3.4 billion devices globally would have it installed, up from 1.2 billion in 2021. In contrast to a traditional SIM, which requires users to physically input their device, an eSIM is embedded into every device and can be updated and managed remotely. Simply message the carrier to request the activation of an eSIM, and they will often respond with a code that has to be scanned on the new device you plan to use the eSIM on. After that, the eSIM ought to function. Activate an eSIM right now with Simbye!
