Core Viewpoint - The release of Apple's iPhone 17 has made eSIM a hot topic, particularly due to the changing stance of domestic telecom operators regarding eSIM support [1][2]. Group 1: Beneficiaries of eSIM - The primary beneficiaries of eSIM technology are mobile manufacturers, as it provides an opportunity to drive new phone sales by leveraging network upgrades [5][6]. - Device manufacturers also stand to gain, as the current market is highly competitive, and eSIM upgrades can provide a stable revenue stream without intense competition [11][10]. - End customers benefit from eSIM, but the extent of this benefit is limited due to various operational complexities and security concerns associated with switching carriers [14][15][19]. Group 2: Telecom Operators' Perspective - Telecom operators view eSIM as a double-edged sword; while it may facilitate customer acquisition, it also lowers the barriers for customers to switch providers [22][24]. - The competitive landscape may intensify as all operators adopt eSIM, leading to a focus on service quality and pricing rather than technological differentiation [27][28]. - Operators may face increased costs and resource allocation to support eSIM, similar to the impact of number portability, without significant gains in market share or profitability [29][28]. Group 3: Media and Investors - Media outlets, particularly self-media, benefit from the hype surrounding eSIM, as it generates traffic and potential advertising revenue [32][33]. - Investors in the stock market can capitalize on the fluctuations caused by eSIM-related news, even if the underlying companies are on a downward trend [37][38]. - The promotion of eSIM often generates more value through media coverage than the technology itself, highlighting the disparity between perception and reality [39].
