E sim card is embedded SIM card. The traditional SIM card is directly embedded on the device chip instead of being added to the device as an independent removable component. The simplest and most intuitive thing brought by this is to save space. The soldering process directly adds the SIM card to the product, and it becomes easier for users to switch operators and packages (not currently supported in China). Therefore, the eSIM card has the advantages of smaller size, high stability, one number multiple terminals, and convenient use.
Reduce size: reduce the card slot space on the hardware, making it easier to achieve miniaturization of terminal equipment, such as smart watches and car equipment;
High stability: embedded chips make the product more shock-resistant, high-temperature resistant, and more reliable , To adapt to a harsher working environment;
One number multi-terminal: With the competition and development of operators, the way of using air card writing is more flexible to switch operator data;
Fast and flexible connection: When the operator’s signal is not Hershey can also switch other operators easily.
It is estimated that by 2020 the number of connected devices in the Internet of Things will reach 20.4 billion, and the corresponding market value will be as high as 6 trillion US dollars. The future market prospects of eSIM cards are very broad. Application areas include Internet of Vehicles, wearable devices, smart homes, smart homes, remote smart meter reading, wireless mobile POS machines, location tracking, and so on. By 2020, there will be a total of 125 million eSIM connections worldwide, with a total value of approximately US$174 billion.
eSIMs will promote the Internet of Things revolution, facing the Internet of Things era, eSIM has unlimited value. A simpler and more flexible eSIM solution is a key factor in promoting the scale of the Internet of Things. In fact, for the Internet of Things, eSIM will also give birth to a new business cooperation model and reconstruct a multi-party win-win ecosystem. eSIM will also bring many changes in the Internet of Things era. Many IoT devices are unattended and have no interactive interface. They are "passive" and will not "complain". There is a "last mile" gap between the network and the terminal, and between the operator and the terminal equipment vendor. .
The cooperation in all aspects of the Internet of Things using the eSIM ecosystem will be closer. As shown in the figure above, eSIM can effectively promote the expansion and expansion of the Internet of Things in an environment where OEM manufacturers, operators, SIM suppliers, eSIM equipment suppliers, and IoT platform developers work together. In terms of providing security, scalability, interoperability, and functional connectivity for future IoT devices, establishing such partnerships and developing mutually supporting services will be key.
Application scenarios of eSIM in the Internet of Things
According to the assessment of the GSM Association (GSMA), the Internet of Vehicles, smart medical, public utilities, and smart logistics will take the lead in benefiting from eSIM.
The Industrial Internet of Things includes industries such as smart cities, smart agriculture, smart transportation, smart manufacturing, and smart medical care. Due to the large differences in different industries, the requirements for connection management are complex, and management dimensions and management difficulties seem to be increasing day by day.
For example, more and more national industrial enterprises and construction companies wear smart bracelets to their employees to monitor key variables such as air quality, heart rate, and location to ensure their health and safety under harsh conditions. eSIM uses OTA over-the-air download technology to simultaneously erase and write SIM cards for tens of thousands of devices, which not only simplifies management, but also improves the practicability of smart bracelets and employee satisfaction.
Smart logistics is also one of the typical application scenarios of eSIM. Logistics fleets spanning different cities and even countries are mostly equipped with sensors that collect various data. A large amount of telemetry data is collected every day, and its integrity and circulation are very critical. eSIM not only reduces roaming costs, but also prevents data interruption due to poor signal or SIM card replacement.
With the further popularization of IoT applications and the gradual maturity of new technologies such as 5G communications and artificial intelligence, the advantages of eSIM in terms of high integration, miniaturization, maintenance-free, and long-term connections will further emerge.
Beijing Miracle IoT is a professional eSIM solution provider, promoting the popularization of eSIM technology in IoT applications and providing a variety of eSIM services.
Implementing traffic hosting services to effectively reduce customer operating costs by subtracting customers;
Better tariff optimization solutions, recommending better packages based on actual traffic usage;
The eSIM information management platform can query the card's online status, tariff status and output data tables for management statistics;
written at the end: Although e-SIM seems to be a substitute for the bulky physical SIM card, this small change can cause Greater chain reaction. The traditional roles of OEMs and operators will be redefined, and users will get more benefits. The eSIM connection is the key to the Internet of Things. It is estimated that only network connection can bring about 25% of Internet of Things revenue to large operators, and the remaining revenue will be realized through the value-added services they provide. Therefore, the promotion of eSIM will help accelerate the IoT revolution.
