What is eSIM? An Introduction to Embedded SIM Technology

What is eSIM? Just think of a world where switching mobile carriers is as simple as downloading an app. Welcome to this new eSIM world. The demand for modes of connectivity that are flexible and efficient has literally reached saturation as people’s reliance upon smartphones and gadgets for a majority of their daily jobs has increased. eSIM is revolutionary innovation in mobile technology, promising to ease the burden of managing our digital lives.

An eSIM, or embedded SIM, is a digital version of the traditional SIM card embedded right straight into a device. It is a digital SIM with the identical role to a plastic SIM. It is integrated right into a phone, into the body of the phone, such that it cannot or does not need the practice of being removed. The most revolutionary mobile-connectivity concept is making every operation very convenient and highly versatile. This article discusses what eSIMs are, how they differ from normal SIM cards, why they are advantageous, how the setup is done, applications, and possible drawbacks.

What’s an eSIM? Definition:

An eSIM, or embedded SIM, is quite a leap forward in terms of SIM card technology. An eSIM is a very small chip directly soldered into the device motherboard, as opposed to being hardware that goes into the phone. More aptly, it is an eUICC-compliant, reprogrammable chip that works with a variety of carrier profiles. Through software updates, a user can switch between profiles without ever physically handling it. In a nutshell, it basically functions like a physical SIM card but with a bit more flexibility and convenience.

The eSIM technology is based on the eUICC standard, through which profiles from different carriers can be provisioned over the air. A user can thus land a carrier profile over the air on his device, download it automatically, and activate it directly on the device without any physical SIM card. It supports the eUICC standard within eSIM technology for implementation over various device and carrier characteristics, making this a universal solution for mobile connectivity.

Technical Details:

The core of the eSIM technology is based on the technical architecture; precisely, it’s the eUICC. It is the programmed device; the profile of the SIM information is stored in the device. So here is how it works:

eUICC Architecture: An eUICC is a Secure Element that can host multiple SIM profiles, manage the lifecycle of these profiles, and, therefore, allow or disallow their activation or deactivation. This is different from the original SIM card, in that the profile is assigned with a read-only attribute at that stage in the process. The ability provided by eUICC is really significant for flexibility and adaptability.

Remarkably, one of the dominant features of eSIM technology is OTA provisioning, in which the carrier profile is received over the air. So when the carrier or a plan is shifted, the respective profile information of the carrier is downloaded straight into the device. Activation is normally carried out after providing the owner of the device with a QR code or activation code; upon scanning or entering in the device, the CSP profile is downloaded in the eUICC.

Security: The eUICC is built with solid, highly secure features that make it tamper-proof to unauthorized access. Carrier profiles populated over it are secure through encryption and security protocols, where any changes are manageable only by privileged users.

How an eSIM functions: The general procedure involved in joining an eSIM includes the following:

Get Carrier Profile: Customer needs to visit the website or shop with that carrier and request for an eSIM profile. A back-provisioned QR code or an activation code is provided back to the customer for use. ESIM activation: this is when your device will request a download of a profile from the carrier over the network to eUICC by scanning a QR code or entering the activation code into the device. Profile Management: Once a profile has downloaded, it can be activated or even deactivated when there is a necessity. Users can always shift from one profile to the other that is saved on the eUICC by the help of device settings and do so easily.

Over time, eSIM technology has rapidly picked up and now has support from big device vendors such as Apple, Google, and Samsung in their new models. For instance, the iPhone XS Max can now support a dual SIM system using an eSIM with a traditional SIM card slot. Similarly, the new Google Pixel 3 and its younger brothers come with an inbuilt eSIM, by which it is quite easy to switch from one carrier to another and vice versa, without the requirement of any external hardware.

This technology is not only available in smartphones but also available in tablets, wearables, and IoT devices, thereby increasing the application and improving the connectivity options for the devices. eSIM technology today offers huge strides over traditional SIM in terms of flexibility, security, and convenience. By replacing the SIM card with eSIM implementation and OTA provisioning, the user experience will be seamless and smooth.

Difference between eSIM and Regular SIM Card

From ordinary SIMs to eSIM technology, this is a very important step in managing mobile connectivity. Understanding the value and realizing how beneficial eSIM is will require one to delve deeper into the differences between the two.

Physical vs. Digital

It is the traditional SIM card, which is a physical entity used to create the association of devices with the mobile network. It comes in the size of a standard SIM, micro-SIM, or nano-SIM, which is accordingly associated with the device slot. On the contrary, an eSIM is a small chip mounted on the motherboard of the device. It is, therefore, digital in a way, meaning there will be no worries of a physical card and definitely all the logistics from handling, inserting, and replacing the cards.

The physical nature of the traditional SIM cards makes them not only prone to damage but also to getting lost completely, thus causing a hitch in receiving mobile services. Most mobile service users need tools to first eject SIM trays from the device—a process that is sometimes cumbersome and might cause errors. The eSIM, being embedded within the device, makes it very convenient and stronger, avoiding all these headaches and hitches.

Configuration and Activation

Activating a physical old-style SIM usually involves some physical actions: visiting the manual procedure of inserting it into a SIM slot in a device, configuring settings, and sometimes even rebooting. This leads to the manual type of process and will hence most probably be time-consuming and a frenzied job, especially when end users frequently switch SIMs due to the above reasons.

By contrast, an eSIM is activated digitally. For the most part, the eSIM is usually activated by scanning a QR code sent by a provider or by keying in an activation code through the device settings. It is much faster and way less cumbersome than, for instance, going through the motions of dealing with physical SIM cards when one purchases a new plan or changes the provider. Most carriers could simply give a person a QR code in their email, and the user would scan it on their device, and within minutes, the eSIM profile would be downloaded and activated.

Apart from this, the whole activation process is digital. When it is digitized, one can have multiple eSIM profiles on one device, and people can easily switch from one to the other through a device’s settings without the need for a physical SIM card, instantly. It is especially useful for people who, due to their official or personal reasons, move from one place to another repeatedly and hence require multiple carrier profiles interchange.

Flexibility in the Carrier Switch

It’s usually very inconvenient and time-consuming because, in most cases, it’s difficult to replace the old card with the new card due to incompatibility.

Likewise, it is convenient to move from one service provider to another with eSIM technology. One can easily download a new eSIM profile into the device through the device and change the service provider. This is easily done in the majority of devices through a mobile application or in the settings of the device; one does not need to visit the card physically. For example, he can easily download and install an eSIM card if he is traveling overseas but does not want to pay for roaming services. In quite a literal sense, it actually takes less than a few minutes.

Multiple Profiles

A traditional SIM card can bear only one carrier profile at a time. That means to swap between multiple carriers, you will find it quite bothersome to keep changing different SIM cards.

The inability to carry more than one carrier profile at an instance greatly limits the application of an eSIM. This means that one can freely switch from one carrier to another, or from one service plan to another, without the need to swipe a card. For instance, one can keep the other for the home carrier and one other for a local carrier in the country they often stay in. It is easy to switch from the home carrier profile to the local carrier profile by navigating to a profile of choice under the device’s settings menu.

Remote Management

Traditional SIM cards require the device to be in hand, in case any changes occur, at the card-swapping information update. This may be quite cumbersome, especially in remote locations or used in an application of IoT.

They can be remotely managed as well with e-SIM. A carrier can do an over-the-air update, or for that matter, a new profile push to the eSIM. This, in turn, will allow the end user to update services without any kind of physical intervention, which again is great practice when one needs to solve issues related to IoT devices that are in an environment far-reaching or hard to get at.

Security

Security is one area in which eSIM cards can outdo the traditional ones. The eSIM profiles are remotely controlled, hence being associated with more security features. For example, in the event of the loss or theft of your device, you are privileged enough to disable the eSIM remotely so that no one else will be able to use it. On the other hand, traditional SIM cards are swappable and for instance, if one is stolen, an added concern to security is that the person might use it on another device. Basically, transitioning from the traditional SIM cards to eSIM technology brings with it a lot of benefits but, above all, convenience, flexibility, and security. It cuts down on the use of cards, being digitally activated and managed, and is, indeed, a modern solution befitting the growing needs of the mobile user landscape in this growing Internet of Things.

Advantages of Using eSIM

The introduction of eSIM technology brings to the table the myriads of advantages that it has over the user experience with their mobile networks and devices. Ranging from convenience, security, and flexibility to cost savings, this makes it difficult to resist by most users and businesses.

Convenience:

One of the major benefits of the eSIM technology is convenience. This makes the handling of physical SIM cards very inconvenient for activating, deactivating, or changing the carrier, due to mostly the number of users who travel often and who require handling multiple lines.

Using eSIM makes it easy for a user to change a carrier or plan by altering the device settings, without a shop visit and without time spent waiting for the physical SIM card to arrive. You can keep switching carriers with your existing mobile-to-mobile carrier by downloading the new carrier’s profile onto the eSIM and activating it in minutes. Since it is totally digital manipulation of cards, the process, again, goes through seamlessly.

Besides this, having a second line is quite easy using eSIM technology. Many new phones now have dual-SIM functions, using an eSIM. It is now possible to have a primary and an auxiliary line in a one-device setup, without the hustle of getting a second physical SIM card. This is very handy, for example, when one needs to keep a work number separate from his personal number on one device.

Security:

From a security point of view, in comparison to the classical SIM card, the eSIM is an improvement. An eSIM is theft- and fraud-secure since eSIM profiles can be managed from a distance. The subsystem of an eSIM can be disabled from a remote area in the event that the device is stolen or lost, thus averting unauthorized access to the network or personal data. In fact, this is one of the secure measures an eSIM takes, as compared to a physical SIM card, which is removable and can be inserted in another device in case it is stolen.

In addition, eSIMs offer a higher level of encryption in which SIM profiles cannot be accessed by unauthorized hands or tampered with, thus boosting the security aspect of IoT as one of the finest ways to ensure the safety of devices in applications deployed in unsecure places.

Flexibility:

Among other reasons, eSIM technology provides unprecedented flexibility in the management of mobile connectivity. A whole lot of carrier profiles could be stored in one eSIM, making it very fast and convenient in switching between carriers or service plans. More importantly, this proves most valuable to frequent travelers, who can easily switch to local carriers to help them avert huge roaming charges. This is much better than buying a new SIM card in each country; rather, a user with an eSIM downloads a local carrier profile and activates it on the user’s eSIM.

For example, a business traveler can ensure their main carrier profile is active in-country, and then download temporary profiles from local carriers when they go out of the country. The switching happens through device settings, thus avoiding the associated pain of physical SIM-swapping processes, and therefore saves time and energy.

Cost-Efficiency:

The use of eSIM technology in mobile networks can accrue cost savings for both consumers and operators. With the use of this technology, a consumer is able to enjoy the best rates and offers without worrying about being tied down for a long period of time in a contract, since easily changeable carriers and plans will be executable. Again, the ease of changing carriers can even bring about more competitive pricing by mobile network operators to benefit the consumer.

For mobile network operators, eSIM lessens operational costs associated with making, delivering, and managing physical SIM cards. Digital provisioning of SIM profiles simply means that the process of SIM activation and management of mobile subscriptions is eased. All this now becomes very cost-effective and an operational exercise from which benefits are passed on to the end consumers in the form of better price points and service offerings.

Travel:

The ability to switch to a carrier of choice locally, without incurring expenses purchasing another SIM card and inserting it into the gadget, makes global traveling easier. This feature will exceptionally offer benefits to the frequent traveler and save an individual from the high calling charges that pertain to roaming, just like a local rate. Travelers will be able to download and activate local carrier profiles upon reaching their destinations, providing quite immediate and inexpensive connectivity.

For example, he will not necessarily have to identify a local SIM card vendor in a foreign country because he has an option to download the local carrier eSIM profile before departure or immediately upon landing. The smooth handover from one carrier to another fits the travel experience through assurance of getting what one expects from this sector.

Device Management:

eSIM technology greatly benefits businesses that need to manage large fleets of devices, mostly in IoT applications. eSIM enables the management and remote provisioning of the connectivity of these devices, thus reducing the need for physical intervention or maintenance. This capability is most important in devices sent into locations or areas that are hard or even impossible to access, like environmental sensors, smart meters, and industrial equipment.

Moreover, on-the-fly remote update of carrier profiles, management of subscriptions, and troubleshooting of connectivity issues can be effected, which greatly eases centralized management and further enhances operational effectiveness by significantly reducing costs.

Environmental Impact:

This also presents the environmental benefit, as eSIM technology essentially does not use a physical SIM card. Most environmental waste in production, packaging, and distribution of a traditional SIM card emanates from the carbon emission. An eSIM shall cut down on that footprint because there shall be no physical card in the process of connecting a device.

How to Activate eSIMs

Activation steps are rather easy, but they slightly vary from device to device and from a carrier to a carrier. This process has been designed to be easy-to-use, which means even a person very new to eSIM technology can easily activate their new mobile plan without much hassle. Here is an in-depth eSIM setup guide:

Compatibility Check:

Verify your device is eSIM compatible before you proceed. Most new devices already come with in-built eSIM support.
