Freedom of Communication: Overview of eSIM Technology

In 2024, eSIM technology is gradually gaining popularity among leading smartphone brands and users. It has a number of advantages and should also facilitate the transition from one operator to another, allowing you to use mobile communication without borders. Today we will explain in simple words what an international eSIM is and compare it with a physical SIM.

What is eSIM?

eSIM is a built-in SIM card that does not require the installation of a physical chip in your mobile device but offers the same functionalities as a traditional SIM card. New smartphones (as well as smartwatches and tablets) may already come with eSIM cards. Additionally, since eSIMs do not require a physical SIM card for installation, you can purchase and activate one before traveling abroad. To do this, you need to choose a provider (such as ESIM-Man, Airalo, or Airhub), purchase the desired wireless plan, and follow the instructions to download and install it on your device. Like traditional SIM cards, prepaid eSIMs come with a fixed amount of data, SMS messages, or talk minutes that you can use while traveling. You can select the plan you want, and generally, you can also easily extend its validity directly from the app.

Why is eSIM Better Than a Traditional SIM?

Firstly, with the introduction of eSIM technology, smartphone manufacturers gain additional space inside devices. This space can be used for installing other components, which could, for example, lead to larger batteries in the future. In addition, because the eSIM is digital, users can easily change carriers and "SIM cards" without physically removing the card. All actions can be performed online, making the process much easier. Devices that support eSIM allow the use of multiple data plans simultaneously. For example, users can make calls on one line while using the internet on another. This makes the device more flexible and convenient to use. It is also worth noting that eSIM cannot be removed from the device, which enhances security. Even if the smartphone is stolen, access to the card and data is maintained as long as there is a network connection.

Who Does eSIM Technology Suit?

The new eSIM technology is perfect for all subscribers who value functionality and their own mobility. This card can be an ideal solution for various spheres of life. For example, it can be used to analyze data, collect information, coordinate actions, and automate those areas of life that can be linked to a smartphone. eSIM cards are compatible with different devices: smartphones, tablets, smart watches, smart homes, and even cars. The main condition is a strong and stable Wi-Fi or mobile internet signal. So, who are the main consumers of eSIM cards? Here they are:

• Travelers. It allows convenient and cheap connections to networks abroad.
• Technology enthusiasts. They use them to interact with the latest devices and technologies.
• Regular users. It can be used to get multiple numbers and manage multiple data plans at the same time.
• Businessmen and companies. This solution allows for convenient management of corporate devices and more.
• Residents of remote regions. In some regions, this is the only way to access mobile communication.
