A Hong Kong eSIM is a virtual SIM card that connects you instantly to Hong Kong mobile networks (CSL, 3 Hong Kong, SmarTone, CMHK) without a physical card. Plans start at ~$3 for 1 GB, up to ~$50 for unlimited.
Do you really need an eSIM? Hong Kong does not benefit from free EU roaming. To avoid high roaming charges, an eSIM is strongly recommended for all trips.

Unlike European Union countries, Hong Kong does not benefit from free roaming. Your home plan will be very expensive (often $5-10/MB). An eSIM is therefore strongly recommended for all trips to Hong Kong.
Hong Kong is a Special Administrative Region with its own networks and regulations. Unlike mainland China:
If you also travel to mainland China: get a separate eSIM for China (or a regional Asia plan covering both).

For all travelers to Hong Kong, an eSIM is strongly recommended as free EU roaming does not apply.
If you choose an eSIM: GoMoWorld 10 GB with code ESIMP offers the best value.
For heavy users: Holafly unlimited eliminates any stress.
Important: If you also travel to mainland China, get a separate eSIM for China (or a regional Asia plan).
