Before purchasing an eSIM, consumers should first confirm the data provider to avoid unknown low-cost cards. If still preferring the convenience and price advantages of eSIMs, consider using "native eSIMs" which directly utilize the network resources of the local telecom operator at the destination. However, when using native eSIMs, it is important to note that if the installation steps require "turning on roaming," it might not be a true "native card." Central News Agency (CNA website) eSIM services have gradually become the preferred choice for people traveling abroad in recent years due to advantages such as immediate purchase and use, and no need to replace physical cards. However, a research report points out that the solutions of mainstream travel eSIM operators assign IP addresses to devices that originate from Chinese telecom operators, raising public concerns about cybersecurity. cacaFly Holy Ocean Technology Chairman Chiu Chih-hung posted on Facebook, mentioning a paper published by a Northeastern University research team last August at the 34th annual conference of the non-profit international academic organization USENIX, titled "eSIMplicity or eSIMplification?". The research team tested 25 mainstream travel eSIM operators' solutions and found that the public network IP addresses assigned to devices did not match the user's actual location. For example, when using Holafly's eSIM for internet access, headquartered in Dublin, Ireland, the assigned IP range belonged to the Chinese telecom operator "China Mobile." Chiu Chih-hung pointed out that China's "Cybersecurity Law" and "National Intelligence Law" stipulate that telecom operators operating within China must coopera
