This data SIM card is ideal for business travelers and tourists who frequently travel between China, Hong Kong, Macau, and Taiwan, with varying stays and moderate data usage needs. Specifically, the following groups are particularly suited to this data SIM card: Business travelers who frequently travel between China, Hong Kong, Macau, and Taiwan: One SIM card can be purchased annually for data usage in all four locations, eliminating the hassle of frequently changing cards or purchasing multiple local SIM cards. Long-distance travelers or seasonal travelers: This card boasts a 365-day validity period, suitable for those who travel around Taiwan during different seasons, travel to mainland China for business, or reside in Hong Kong and Macau for extended periods, without worrying about data SIM cards expiring prematurely. Light to moderate internet users: 30GB of high-speed data is sufficient for daily tasks such as Google navigation, map viewing, communication via messaging apps (Line, WhatsApp), and occasional social media video viewing. After the high-speed data is used up, there is still unlimited low-speed (e.g., 512kbps) internet access available, ensuring uninterrupted internet access.

When used in mainland China, it allows direct access to restricted websites such as Google, Facebook, Instagram, and YouTube without the need for a VPN.
