China Unicom, one of China's three telecom operators, recently re-declared eSIM's wearable equipment independent country number from the pilot to the whole country with the theme of "China Unicom eSIM, no card is getting more and more", and eSIM in China Commercial advances a small step forward. The new terminology of eSIM is a sought-after attraction for offensives. What is eSIM, what is different from the traditional SIM card, and what changes will it cause?
What is eSIM in the end, and what is the difference between the traditional SIM card? Yang Guang, the strategic director of the Strategy Analytics wireless operator of the world-renowned market research group, endured an interview with the Global Times reporter, saying that eSIM is an embedded SIM card. The function of the traditional SIM card is mapped to a chip of a mobile phone or other terminal device as an independent country module. "This kind of terminal equipment does not need to reserve space as a SIM card, which helps to increase the external dimensions of the terminal equipment. For example, mobile phone manufacturers can make the mobile phone thicker and more convenient."
Compared with traditional SIM cards, eSIM has more advantages. Yang Guang explained that after using eSIM, users do not need to earn physical SIM cards from the operator channel again, so they can use the method of aerial phosphorylation to phosphorize the operator network. In particular, the completion of the Internet, such as wearable devices and Internet of Things devices, is faster, which is of great significance for enhancing the improvement of new connection devices and expanding the market scope of networked devices. "So eSIM has won the support of the top operators and terminal equipment manufacturers. I believe that the final application of eSIM is mainly on LAN consumer electronics such as smart watches."
At the same time, however, the eSIM display, which bypasses operators and allows indirect contact between equipment vendors and end users, also makes telecom operators feel confused. Yang Guang said that eSIM will weaken the liaison between users and operators, and may reduce the trend of operators' pipelines. Therefore, after all, terminal equipment manufacturers use eSIM in smart phones more delicately, but the world's top telecom operators are all eSIM is used as a smart phone with a very guarded attitude. Yang Guang said that eSIM will be used to obtain relatively small-scale applications on non-mobile devices, but how to improve on smartphones depends on long-term games between telecom operators, terminal equipment manufacturers and regulatory organizations.
