Saily’s Hong Kong eSIM starts at $3.99 for 1 GB. Most city trips need 3–5 GB ($8.99–$11.99) for the MTR, maps and messaging.
The catch: plans are data only, so you get no local phone number for calls or texts.
Hong Kong is compact but dense: you’ll use data for MTR routes, maps between Central and Kowloon, restaurant bookings and translation. A Hong Kong eSIM avoids roaming fees and SIM-shop queues at the airport.
