iPhone14 series, the American version of iPhone14 has become the focus of some people's attention. Before this, the US version of iPhone 2 would be about 1,000 yuan cheaper than the Chinese version, and the user experience is no different from that of the Chinese version, but the US version of iPhone 14 closed this door for domestic Apple fans. Because the SIM card of the US version of iPhone 14 has been cancelled, it fully adopts eSIM technology.
In addition to Apple , the media said Samsung also announced that S23+ will adopt eSIM technology that does not require physical SIM insertion. As two giants in the global smartphone market, Apple and Samsung's advancement of eSIM technology seems to have made eSIM a trend.
. What is worthy of attention from Chinese people is that after Apple and Samsung, the Ministry of Industry and Information Technology of China announced that it is studying and promoting eSIM technology and preparing to apply it on tablets, portable computers, and smartphone devices. When the time is ripe, the application scope of eSIM technology will be expanded.
I believe many netizens are surprised by this matter. What is eSIM? Why do leading companies start pursuing eSIM? Will SIM be completely replaced by eSIM in the future? What are the advantages of
eSIM?
The so-called eSIM is actually an electronic version of SIM. This is a data file similar to a replacement SIM card that can be downloaded through the Internet. With it, users can connect to the mobile network, make phone calls, and send text messages. There is no difference between user experience and SIM cards, and compared with SIM cards, both for consumers and mobile phone manufacturers, they have certain advantages.
For mobile phone manufacturers, canceling the SIM card slot can indeed make more room for the internal space of the mobile phone, such as increasing the battery capacity or reducing the thickness of the mobile phone, and improving the sealing of the mobile phone, thereby improving the dustproof and waterproof level .
In the past decade of SIM card development, the size of SIM card has been evolving to "smaller". For example, the previous SIM card to the later mini SIM card, and later it was reduced to the micro SIM card, and then it became the nano SIM card used. Every time you upgrade, the size of the SIM card will become smaller, and from existence to none, from 1 to 0, is also regarded by many as the ultimate goal of SIM card development.
For users, they don’t have to go to the business hall to open a card or apply for a card, nor do they have to worry about the SIM card burning out and go to the business hall to re-issue it. It is both cost and waste time. At the same time, changing the number of mobile phones and porting the to the Internet will be more convenient. The whole process can be operated online. In addition, eSIM card is more in line with the usage habits of Chinese people, because using eSIM technology can get rid of the limitations of dual-sIM for one machine. One mobile phone can install multiple eSIMs and use multiple mobile phone numbers. Will
replace SIM cards in full?
Simply put, it is difficult for eSIM to completely replace SIM cards! Why?
First of all, for operators' business, SIM cards are largely monthly rent. For example, a main card comes with three sub-cards, and the monthly rent of each sub-card is equivalent to the monthly rent of a SIM card. Although the monthly rent for a single user is very cheap, it cannot withstand the number of hundreds of millions of sub-cards nationwide. Moreover, if eSIM card is popular, users' number portability will complete the entire process online. Even an eSIM-based mobile phone number will roam between the four major operators. How to re-bill, how to maintain customers, and whether the operation process will change may change greatly, and the situation faced by operators in the future will also be very passive.
Secondly, the application scenarios of SIM cards are also changing. According to public reports, the operator's super SIM cards have been put into use in some domestic cities. The so-called super SIM cards are the entrances based on three basic cards, numbers and messages created in the 5G era. Whether it is making phone calls, surfing the Internet, sending text messages, or serving as meal cards, traffic cards, access control cards, or even as car keys. 5G electronic keys and transfers, SIMs have room to exert their value. It is difficult for eSIM cards to replace SIM cards in this regard!
In addition, the difficulty of control is increased. If eSIM technology is fully opened, many developers may bring point-to-point encrypted call technology to users. Although it can improve user privacy, it will seriously breed illegal and criminal behavior. If overseas developers participate, these key links will not be avoided. If they can master our call information and data, the consequences will be unimaginable.
Previously, the Ministry of Industry and Information Technology mentioned that effective measures should be taken to ensure the management rights of the eSIM platform and the card writing rights of the eSIM terminal, and no other enterprises shall be authorized to activate relevant permissions in any form. This also means that with the advancement of eSIM technology by the Ministry of Industry and Information Technology, it will release the authorization of eSIM to terminals under authorization, and combine it with the super SIM cards launched by operators in many domestic cities. Therefore, it is not difficult for us to draw the following conclusion: eSIM will coexist with SIM cards in the future, and SIM cards will not be completely replaced!
