The numbers of smartphones, smartwatches, tablets, and laptops equipped with embedded electronic SIM (eSIM) technology are increasing. This advancement allows users to forego the use of physical SIM cards, enabling them to insert a small phone card into their smartphones.
Apple’s iPhones have included eSIM technology since the iPhone XS release, while Google’s Pixel 3 and Samsung’s Galaxy S20 also feature this technology. Users can verify if their smartphones are equipped with an eSIM by visiting the manufacturer’s website and reviewing the technical specifications.
The eSIM card cannot be removed from the smartphone because all necessary data is stored in it as a profile file. Users no longer need to wait for a physical SIM card to be mailed or emailed to them. Instead, they can now reserve the eSIM profile online by scanning a QR code from the service provider’s customer portal.
The German-based Testing and Product Certification Organization stated that users can often request the eSIM card directly through the application provided by the mobile communication service company. This function has revolutionized the mobile services market by allowing travelers to easily book mobile communication packages worldwide and activate them on compatible devices quickly, without the risk of losing a physical card in the mail.
Smartphones with eSIM technology often also offer a physical traditional SIM card slot, enabling users to use two lines or subscriptions simultaneously. The transition from traditional SIM cards to eSIMs reduces plastic and electronic waste, eliminates the mechanical slot for SIM cards in smartphones, and minimizes the risk of inserting a phone card incorrectly.
Leading companies like Apple and Samsung enable users to transfer profile data from a traditional SIM card to an eSIM if both the smartphone manufacturer and the mobile communication service provider support this function. This transition also allows smartphone manufacturers more design freedom, as eSIMs occupy significantly less space than traditional SIM cards.
