eSIM technology is unstoppable with 3.2 billion devices estimated to be in use by 2025.

The hardware that we use to manage our lives and access an expanding world of online material has radically altered over the past 30 years in cell phone technology, from hardware that was primarily designed for voice and SMS to hardware that has undergone this transformation. Phone technology has seen significant evolution. One component has remained constant in devices over the past 30 years, though: the SIM card. What is an eSIM card and their benefits find out below.

Since its creation in 1991, Subscriber Identity Module (SIM) cards have been used billions of times. In actuality, there are more of them in use than there are human beings on the earth. SIM cards have always served the same function, which is to allow users to use voice and SMS messaging services by establishing their identification to a mobile carrier. With the ability to encrypt speech and data services as well as transmit communications between devices, technology has become smaller and more functional.

SIM cards, though, are starting to feel a little stale. When you obtain a new phone, switch service providers, or wish to use a local carrier to roam abroad, they’re awkward to install and difficult to switch over.

Additionally, the majority of SIMs are made of plastic, which is bad for the environment and the carriers’ own carbon footprint targets.

Presently, it appears like the classic SIM card’s era may be coming to an end. As a potential replacement for current SIM cards, embedded SIMs (eSIMs) are gaining acceptance all over the world.

What Is an eSIM and Where Are They Used? what is an esim card

An eSIM is a little chip that resides inside of your smartphone as opposed to a conventional card. It is impossible to remove the hardware. The information kept in an eSIM, however, is programmable by design. Without having to wait for a physical SIM card to arrive in the mail or go to a store in person, you may quickly digitally activate yourself on a provider’s network. Additionally, it implies that you are able to use several operators’ and different numbers on your phone with the same eSIM. One for business, one for travel overseas, and one for personal usage, for instance.

Many of the most recent models from the largest phone manufacturers in the world now support eSIMs, including the iPhone 12 series from Apple, the S20, S21, and S22 from Samsung, and the Pixel 3 from Google. eSIM is now available alongside classic SIM capability for many of these brands; it has not taken the place of older technology. This is because, despite the desire of consumers and businesses to embrace this technology, certain operators still do not support eSIMs.

In the US, eSIM is supported by Verizon, AT&T, T-Mobile, and DISH, with activation typically made easy using QR codes or applications. With providers like Orange and Vodafone, eSIM is accessible in more than 40 countries across Europe. According to Juniper Research, there were over 1.2 billion eSIM devices in use as of 2021, and it is very possible that this figure has gone up in the last year.

eSIM Immediate Benefits what is an esim card

Customers who use eSIMs immediately save money by not needing several handsets for different uses, such as one for business and one for personal use, and can switch carriers with ease without having to go to a store or wait for a new SIM to arrive in the mail. In some circumstances, this might even result in savings for businesses by preventing the purchase of several phones for staff members.

Using a local eSIM and taking advantage of local rates may be less expensive and simpler for customers who frequently go overseas. The same degree of flexibility will be made available to corporations for their employees who must travel abroad.

Additionally, eSIM technology may provide greater security. If a phone is stolen and has a traditional SIM, the criminal can easily put in a new SIM and switch the phone to a different network. When the user profile needs to be authenticated online, doing this with an eSIM is not as simple.

In addition, the GSMA, which represents the global communications sector, announced this month the launch of its eUICC Security Assurance scheme (eSA), which aims to guarantee that new eSIM products are resistant to a variety of high-level assault threats. This will only contribute to higher eSIM technology security standards.

eSIM long term benefits

eSIMs have a number of additional long-term advantages. Customers now have a simpler way to switch service providers thanks to eSIMs, which encourages healthy competition among providers and leads to increased network efficiency and client satisfaction, said Luc Vidal-Madjar, head of IoT and eSIM solutions at BICS for IBTimes. We will, off course, observe an improvement in general service levels across the telecom sector as the technology is more extensively deployed.

The space that eSIM technology frees up in devices can be used to reduce the size of the device, increase battery life, or improve other capabilities like the camera, which is useful for all those influencers out there. As manufacturers discover new ways to utilize the area once held by SIM cards, the functionality of smartphones should advance. Another major advantage of eSIM is its ability to reduce plastic and electronic waste. As more and more SIM cards, along with the supplementary work devices that many of us own, are taken out of circulation, this will aid in efforts to achieve carbon neutrality.

Additionally, eSIM technology makes it simpler to integrate cellular connectivity into a variety of gadgets, including connected household appliances, smart meters, and machinery. In a variety of different industries, it will hasten the development of IoT devices and their use cases. Additionally, eSIMs can significantly simplify the process of allowing connected devices to roam across borders without the need to switch SIM cards for businesses that have linked devices that must cross borders – think, for instance, of connected devices on ships.


The adoption of eSIM technology is on the rise, with 3.2 billion devices estimated to be in use by 2025. The majority of new handsets already support the technology, and consumer and business demand for it is growing. Although some carriers may be reluctant to embrace the technology because it could increase churn, they cannot afford to do otherwise. what is an esim card

So, if you haven’t checked to see if your carriers and gadgets can handle eSIM, do it right away! And … if your Android mobile phone doesn’t support eSIM, there may be a solution for you:

Once installed in the smartphone, you can use the Card to download all eSIM profiles online. All you have to do is insert the Card into the SIM card slot of the smartphone, download the free APP from the Google Playstore and then simply scan QR codes for all areas of application. The Card can store more than 10 eSlM profiles.
