Suitable for the following groups: Business travelers frequently commuting between the Mainland, Hong Kong, and Macau: Share data and voice minutes across all three regions without swapping SIM cards; access the internet via a Hong Kong IP address; and directly access overseas sites like Google and Instagram from the Mainland without needing a VPN. Users needing a low-cost way to keep their number active: There is no fixed monthly fee; the number can be retained indefinitely as long as it remains valid (usually extended by topping up or purchasing data packages), making it ideal as a backup number that is rarely used but needs to be kept. Cross-border online shoppers and users requiring local registration: Users can apply for a virtual Mainland secondary number—enabling a "one SIM, two numbers" setup—to conveniently receive Mainland verification codes and register for local apps and bank accounts. Users of cross-border shopping and overseas platforms: Since the card comes with a Hong Kong mobile number and can seamlessly receive overseas SMS messages while in the Mainland, it is perfect for registering accounts on overseas platforms (such as ChatGPT, PayPal, and various international e-commerce sites).
