From the initial standard card (SIM), small card (MicroSIM) to ultra-small card (NanoSIM), it is not difficult to find that the SIM card has been developing in the "small" direction, and now, the operator has even introduced an eSIM. chip. On May 25, China Mobile launched the first self-developed 4GeSIMSoC chip - C417M-S, C417M-D.
The concept of the eSIM card is to embed the traditional SIM card directly into the device chip, instead of being added as a separate removable component to the device. The user can perform the functions of surfing the Internet, sending messages, dialing, etc. in the mobile terminal without inserting a physical SIM card. .
Mobile terminals have bottlenecks, eSIM locks the Internet of Things
Although eSIM is very abstract, it is not a new thing. The most common is our smart watch, AppleWatch3, which can share numbers and traffic with mobile terminals without the need for a SIM card, and supports mobile app functions such as making calls, sending messages, listening to music, and socializing.
Multi-terminal No. 1 is a key advantage of eSIM development. You may have doubts that most people only have one mobile phone, and smart watches are not essential. Does eSIM still have its own market?
Indeed, from development to application, after several years of development, eSIM's application on the mobile side is not as optimistic as expected, but it has brought the development of the Internet of Things market to spring.
With the development of the Internet of Things, a family's mobile terminals are no longer limited to mobile phones, televisions, electrical appliances, etc., and various wearable devices, human body monitoring devices, car networking, smart homes, smart homes and other applications are entering our lives. For these smart devices, communication and networking are undoubtedly the basic functions.
Imagine that if each device requires a separate IoT card to operate, we will face different terminals every day, which will undoubtedly increase the personal management cost. In this case, eSIM is a better choice.
In addition to solving the problem of personal number one terminal, eSIM will also be deeply applied in the development of IoT enterprises and the construction of smart cities.
In the era of the Internet of Things, eSIM has a coup
Different from the traditional SIM card, eSIM adopts the mode of remote write card, which can directly store information to the terminal and then activate it. Currently, the smallest eSIM card can achieve 2mm & TImes; 2mm, in addition to small size and low cost, eSIM is in the Internet of Things. A unique advantage in device applications.
1. Embedded design; can be widely applied to intelligent hardware with higher requirements for structural shockproof and waterproof.
2. Intelligent IoT; eSIM card enables users to switch between networks of different operators, reducing consumer dependence on operators.
3. Remote configuration; through the smart APP, you can remotely control the switch and purchase the package to realize the intelligent IoT experience.
National eSIM, how far away from us
Although eSIM is currently optimistic in the field of Internet of Things, there is no way to fully spread the market in a short period of time. The main reason is that there is no way to achieve interconnection between operators.
According to relevant experts, eSIM does not have a unified relevant industry standard. The major operators are not sure about how the certificates are unified, who is connected to the number and the operator, and when the remote download method is used. Other issues have not yet been harmonized. Before these problems are solved, eSIM will only be piloted in a small-scale fixed field.
However, with the outbreak of the Internet of Things, eSIM-related industry standards will be accelerated by the market, and eSIM popularization is only a matter of time.
