Roaming charges in Hong Kong depend on the home operator and the exact destination list in its pass. Hong Kong may be priced separately from mainland China, so country-group labels must be checked carefully.
A phone can create charges through background data even when the traveller mainly uses Wi-Fi. Automatic data switching is another common route back to the home SIM.
NoveSIM travel plans are data-only and do not provide a Hong Kong number, traditional calls or SMS. Internet apps continue to work over the data plan.
Quick answer: Verify that the carrier pass explicitly lists Hong Kong, disable roaming and data switching on the home SIM, and select a Hong Kong eSIM for mobile data. Check separate coverage before crossing a border.

Read the destination list precisely
Check Hong Kong by name, along with the daily fee, allowance and fair-use policy. Do not infer inclusion from a China, Asia or worldwide label.
Prevent accidental roaming
Choose the travel eSIM for data and disable mobile-data roaming on the primary line. Pause cloud backups using the app data controls.
Compare the alternatives
An eSIM provides arrival data without changing the physical SIM. A local SIM may help when a local number is needed. Review the Hong Kong eSIM guide.
Plan cross-border travel separately
A Hong Kong plan does not automatically cover another destination. Confirm every country or region before travel and use the offline maps guide as a backup.
