In recent years, mobile phone eSIM card technology has gradually taken its place in technological advancement. This trend is not an exception for the Bulgarian market, where the three main mobile operators offered this innovation. More and more devices now support the eSIM service: phones, tablets, watches, and laptops. All of these devices provide the ability to add an eSIM, complementing traditional SIM cards.
Let's take a closer look at what this innovation is and what its benefits are that make it a preferred choice in the world of mobile communications.
One of the main advantages of eSIM technology is the ability to quickly change subscription plans in seconds. In this way, the need to constantly insert and change a physical card is eliminated, providing flexibility in choosing different services and also saving time going to the office of the mobile operator.
Simply put, an eSIM is an embedded SIM card that can be easily reprogrammed for use with different mobile operators. Devices supporting this technology have an embedded factory chip and software part. The chip replaces the traditional physical SIM card, and the software identifies the different networks. In the context of smartphones, this means the ability to add a second subscription plan, especially useful when roaming, allowing you to change operators through the device's settings. In other words, it is possible to choose the most advantageous mobile operator even while traveling. At the same time, managers in large companies can switch the subscription plans of thousands of devices remotely and in real time. eSIM activation is quick and easy; it involves receiving a card with a QR code that is scanned by the phone, then following a few simple instructions through the device's menu. It is important to note that the QR code card should be stored carefully, as it is necessary if you decide to transfer the eSIM card to another device for various reasons. One eSIM card cannot be activated simultaneously on several devices; therefore, it is recommended to delete it from the old device before the transfer and only then activate it on the new one.
eSIM technology is a natural progression of the evolution of SIM cards that have gone through mini, micro, and nano sizes. With its embedded chip, the eSIM frees up valuable space in modern devices, which becomes especially important in the age of nanotechnology. The process of switching between mobile operators is now as easy as downloading a mobile application and selecting the desired subscription plan. This is especially important when traveling abroad, where roaming is avoided and it is not necessary to visit the offices of mobile operators.
