eSIM technology is a product that its developers have created for the implementation of all the intricacies of a global system of mobile communication, such as GSMA. Initially, it is a standard that is designed for simultaneous storage of several profiles of different communication operators on the same device. Thanks to the use of an integrated electronic circuit, the user can easily connect with networks of different operators without using plastic SIM-cards. Uploading of subscriber profiles is performed via the Internet even for different cellular operators. The user can be confident that his Internet access will be provided through the capacity of his own smartphone or through an intermediary method of local connection. Programmable SIM card is already built into your device. There are such smartphones that support this standard, not the name of a special jack, and it allows such a phone to carry the status of safe and reliable even in the process of searching the desired network. Such devices conduct a remote search of the network, and therefore the user can add and remove mobile operators.
eSIM technology and its strengths
The name eSIM is just an embedded SIM. This is a specification, which is a tool for remotely providing a SIM card to any other device. Among the features of eSIM technology is the free connection of devices to the cellular network, besides these devices can be different, such as tablets, Smart Watch, portable health devices (wearable blood pressure, heart rate, blood sugar) and even fitness bracelets. This tech has become very popular in such regions as the USA, Europe and Asia. There are more than 25 million. person among the users of this technology. For the first time, eSIM technology received the ways of use in Samsung Smart Watch in 2015. After that, Apple and Motorola released devices that support this specification.
XR, XS and XS Max variants of this iPhones technology support this specification. That is why many users can use this with a regular SIM card to use this standard as a simple virtual analogue of it. In both cases, the owner of the mobile phone has the opportunity to choose and, if necessary, change the communication operator an unlimited number of times. Among the important strengths of this tech, there is ease of use. You will not be able to lose or damage the virtual version of the card as opposed to a plastic card with a microchip, and you will not have to stress insert and remove it from the jack. Despite the small size of the latest generation of plastic SIM cards, you can hardly combine them with compact modern devices of various purposes, such as smart watches, portable medical devices, fitness bracelets and sensors.
Among strengths of this tech:
- Quick search for stolen smartphones due to the impossibility of replacing the SIM card.
- Reducing the size of gadgets, including their thickness.
- No communication problems that exist due to incorrect operation (incorrect connector position and deformation).
- Single room for multiple gadgets such as tablets and smartphones.
Another undeniable advantage in using a virtual card is that you can sell your SIM card at any time. Many telecom operators have also noticed some strengths, among which is a reduction in the number of offices and a reduction in the cost of the start-up package. Operating costs for operators are reduced because there is no need to cooperate with dealers or SIM card distributors. There are some abonents that can start a remote purchase of a SIM card and reduce their costs of time and visiting a cellular communication salon. Also, travellers can enjoy this technology, which can buy a suitable tariff plan and download into the phone instead of looking for a profitable service option in local salons, even when they are in another country.
The use of this technology greatly simplifies the process of transition from one operator to another. It is enough for a user of a device with support of the standard to issue an electronic application. The process of connecting the virtual card will not cause you difficulties. So, you just need to scan the QR code from the operator or download the app for your smartphone. You can also use an alternative, such as manually entering the server address and activation code, which also comes from the operator.
