eSIMTrends observes that despite geographical proximity, Hong Kong and Macau maintain separate telecommunications infrastructures. A standard Hong Kong-specific eSIM or SIM will not automatically provide coverage in Macau. Travelers require either a dedicated Macau eSIM or a regional plan that explicitly includes both territories. Relying on a Hong Kong plan in Macau typically incurs high international roaming charges, a trend eSIM users actively avoid.
