Will my Truly Roaming Hong Kong eSIM provide coverage if I visit Macau or Mainland China (e.g., Shenzhen)?

This specific Truly Roaming plan is designed for use exclusively within Hong Kong. Although Macau and Shenzhen (Mainland China) are just a short ferry or train ride away, they operate on different telecom networks, and Mainland China enforces its own internet firewalls. If your itinerary includes travel within the broader Greater Bay Area (Hong Kong, Macau, and Mainland China), we strongly recommend selecting one of Truly Roaming's regional or global eSIM plans to ensure continuous, unrestricted connectivity across all your destinations.
