How much data do you need in Hong Kong?

Hong Kong has ubiquitous free Wi-Fi (Wi-Fi.HK) in malls, MTR stations, and public areas. 1–3 GB is enough for a short city visit. Budget more if skipping Wi-Fi.

Our recommendation: 1–3 GB for a weekend, 5 GB for a week.

Network coverage in Hong Kong

Hong Kong has blanket 5G coverage — one of the world's most connected cities. All three carriers provide excellent service. No coverage gaps anywhere in the territory.

Tips for using an eSIM in Hong Kong

Separate from mainland China. Hong Kong eSIMs are separate from China eSIMs. Google, WhatsApp, and all Western apps work normally in Hong Kong — no VPN needed.

Octopus card for transit. Hong Kong's MTR system uses Octopus cards — no data needed for transit, but Maps helps for route planning.
