Development in the telecommunication industry replacing physical SIM cards with next-generation SIM such as eSIM and iSIM. According to experts, eSIM card users reach around 5 billion by 2030. Why is next-generation SIM technology dominating day by day? The key reason is convenience. eSIM and iSIM are the virtual SIM cards that are directly integrated into the device. Compared to an eSIM card, iSIM is not very popular. These SIMs ensure a strong internet connection without roaming charges.  In this article, I will go through the details of how SIM cards have evolved and how the next generation is becoming the future of hassle-free communication.  Evolution of Physical SIM to iSIM Technology The first SIM card was invented in 1991, which made our device capable of connecting with the other network. It was a big achievement that human beings living miles away can communicate with each other. Then, a big change came in the telecommunication industry after years; the devices became smart, and SIM cards evolved into virtual SIMs.  Nowadays, we use devices that are compatible with next-generation SIM technology. The physical chip card that we inserted in our devices years ago now comes into the market directly integrated into the devices by the manufacturers. This evolution positively affects our lives and improves the way to communicate worldwide. Here is the sketch of how the bulky SIM cards evolved to next-generation SIM technology.  Key Featurters of eSIM and iSIM eSIM is a tiny chip card that is attached to the compatible device hardware. It is the premium solution to access instant connectivity without breaking the bank. Similarly, integrated SIM or iSIM is installed into the device’s processor. Like an embedded SIM, iSIM ensures to provide easy cellular coverage. Both SIMs are specialized to provide flexible and convenient data connection. The key features of eSIM and iSIM include. Features eSIM iSIM Integration Embedded into the device’s hardware Integrated into the device processor Cost  Cost-effective Expansive Activation Remote activation Remote activation Purpose Offer fast cellular network coverage Extensive network coverage Specialized for Smartphones and travel gadgets IoT devices Adaptation  Compatible for wireless devices Limited to IoT devices Why is next-generation SIM technology dominating? Next-generation SIM technology is dominating and taking over the place of physical SIM cards. It become a convenient means of communication because it offers ease and is comparatively lower cost than the local SIM cards and pocket WiFi. Some reasons why it is becoming popular include.  Enhanced Security Compared to the traditional SIM cards, eSIM and iSIM offer enhanced security. The SIMs don’t have any chance of being stolen or damaged. Users’ information is digitally stored in virtual SIM cards. Thus, it has a lower chance of hacking or SIM swap attacks.  Cost-Effectiveness  eSIM card is a cost-effective solution to access connectivity.
