CoreESIM's Hong Kong-specific data plans are provisioned exclusively for operation within Hong Kong SAR. Despite their geographical proximity, Macau and Mainland China (Shenzhen) operate under different telecommunication networks and regulatory frameworks, including China's internet censorship. If your travel itinerary includes visits to the broader Greater Bay Area, encompassing Hong Kong, Macau, and Mainland China, CoreESIM strongly recommends a multi-country Asia eSIM plan designed to cover all these distinct regions for seamless connectivity.
