Typically, a standard Hong Kong local SIM or a CoreESIM specifically provisioned for Hong Kong will not automatically provide service in Macau. While geographically close, Hong Kong and Macau operate under separate telecommunication regulatory frameworks. Most Hong Kong carriers require specific international roaming packages to be activated for use in Macau, incurring additional charges. For seamless connectivity in Macau, CoreESIM recommends a dedicated Macau plan, which connects directly to local operators such as CTM or SmarTone Macau, ensuring optimal performance.
