ESIM will not only bring battery life problems to smartwatches, but also create more information security risks due to its OTA in-flight download mode.How do I write OTA?ESIM service ge zhou min said: 'the Internet of things device, usually in the process of production will be directly embedded into a white card in the device, which contain different operator identification, through a single management platform at a safe distance air transport (OTA), complete the operator safety certification, users don't have to pull out insert SIM card, you can directly select the location of the equipment operator network, and using the local charges in order to reduce international roaming costs.As long as the network standard support, users can freely switch operators, without any restrictions.


Specific to write number mode, jiang peng pointed out: 'watch eSIM using OTA write number action, generally based on GSMA developed sgp.22 specification, through DP+ code number file remote download.If the user change device, you can refer to the existing smart phones don't change card process, with the new equipment to the business hall, operators to void the original device in the code file, and then on new equipment for the user to download a new code file with the original number of binding, so as to realize replacement does not change.'



Clearly, the most needed a second write Numbers, air to write Numbers and the means of direct transmission of OTA and download, also means that a hacker or have a certain technical means of users (for example, is now very common fraud institutions, etc.), all can easily in the process of ordinary users to OTA write number to steal theft of information and data, result in the user data, may be used to further the implementation of fraud and other illegal activities.Moreover, if the user is using the 'number one terminal' service, this information security risk will also be directly spread from the watch end to the mobile phone end.



This is why the three carriers and China academy of information and communications are eager to set up eSIM management committee of the core reason, Jiang Peng told reporters: 'as eSIM technology evolution and industry more and more mature, need TAF and create a unified institution to coordinate the domestic regulators as well as the position of three carriers, standardize business processes.However, in the past two years, progress has been slow due to the failure of the China academy of information and communications technology to get unified support from the three operators on eSIM technology and specification.In order to coordinate their positions, the China telecom academy has set up a committee with three operators to jointly promote the development of the industry.'


On June 17, China academy of information and communications technology formally announced the establishment of eSIM management committee together with China telecom, China mobile and China unicom, which is a strong signal that China has begun to pay attention to all kinds of problems arising from the end of eSIM.According to the introduction of relevant parties, the establishment of eSIM management working committee aims to promote the development, implementation and implementation of eSIM technology in China, and effectively promote the healthy development of eSIM technology and industry in China.The following measures will also provide more reliable security schemes in eSIM information security.



In short, the terminalization of eSIM technology is gradually advancing. The launch of smartwatch market is a good application attempt for terminal manufacturers like apple, huawei, samsung and huami, and the best plan for operators to effectively implement eSIM business.Although the smartwatch market has generously embraced eSIM, it is still worth noting the battery life crisis and user information security risks.From the Angle of power equipment, in addition to rely on the development of the chip manufacturer of existing supply chain solutions to lower power consumption, the OEM in the future in the field of OS system optimization advantages will no doubt be evolved into the key means of related products to compete in the market, in addition to apple, now more and more manufacturers began to intensify efforts to develop the independent intelligent watch OS system, create a differentiation advantage is a good example.


Information security, he thinks, eSIM formally in the field of smart watches in the early period of the commercial will continue to face this kind of problem, this also is the new eSIM management committee provides a good test and regulatory scheme analysis of the case, presumably for the next two or three years later, as the eSIM in the field of intelligent watch the commercial and regulatory specifications and increasingly mature, the smartphone market will also be hungry, overall the eSIM into the great age of the 'IoT terminal'.
