For more than 30 years, the SIM card has been connected to a piece of plastic that must be placed into a slot. The introduction of the eSIM, or integrated SIM card, caught subscribers off guard. What’s that? How does eSIM work, and why is it required? eSIM technology ESIM is a digital SIM. Some supported devices have built-in chips to which you can bind several numbers and tariffs – separate for each country. When moving, you only need to switch SIM cards. At the same time, there is no physical card, so it’s not scary to lose it. And you don’t have to pull out your “native” SIM card, which receives SMS notifications from banks and other services. One of the international operators with reasonable rates for a digital SIM card in different countries is eSimWay. In many countries, eSIM tariffs are cheaper than local SIM cards. And somewhere, for example, in Japan and Cuba, it is easier to use a digital SIM than a physical one. A “global tariff” also operates in more than 90 countries. Why use an eSIM? In most scenarios, eSIM for travelers looks to be preferable to regular SIM cards. Firstly, it cannot be broken, lost, or incorrectly inserted into the device. Secondly, you do not have to look for a paper clip and generally somehow disassemble the device in order to change the number or operator. Thirdly, a virtual SIM card gives flexibility in using different tariffs, as it stores up to 5 numbers. For iPhone users, eSIM activation is a long-awaited opportunity to get a “two-SIM apple”, that is, from one device to communicate on the main number and, for example, corporate. Free Esim Why do eSIM providers offer free mobile communications? The most obvious reason is so we can try the mobile data plan and possibly switch to a new operator. Like in fitness clubs: each club gives you the first trial lesson for free. It is the same with mobile operators, but sometimes there are nuances. To get a free connection, you need to fulfill certain conditions. Advantages of eSIM over physical media: the ability to use several numbers at once; the opportunity to save money on communication. You can set several virtual numbers with optimal rates separately for calls, Internet, and SMS; data protection. When your phone is locked, thieves won’t be able to remove the SIM card to use mobile banking if it is stolen; there is no risk of losing or damaging the SIM card when moving from one device to another; it is now easier for manufacturers to protect the phone from moisture, so there is no need for a separate slot for a SIM card, the connector of which is an additional source for water ingress; you can choose an operator without visiting the offices through the application, which significantly saves you time; there is no “dancing with tambourines-paper clips” to install a new SIM card in a smartphone. Scanned the QR code, and that’s it! In addition, nothing needs to be done; there is no need to buy physical SIM cards abroad; the technology allows, due to the micro-size of the module, to embed eSIM in small devices, for example, in smartwatches. That with classic SIM cards was previously problematic. eSIM is especially handy when traveling. If you have an iPhone, then you have encountered a problem when the local data plan is more profitable, and you have to choose whether to leave your SIM card and receive calls or buy a local one and save.
