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.
