# Does It Work in Hong Kong? (2026-11-11)

Hong Kong has open access to Google, WhatsApp, and social media, but enforces mandatory eSIM real-name registration for local numbers and is geo-blocked by OpenAI and Anthropic.

> **Quick take:** Google and WhatsApp work without a VPN, but ChatGPT and Claude block Hong Kong IPs—use a VPN or a Singapore-routed eSIM to access AI tools.

## Service Compatibility Matrix

- **ChatGPT, Claude & OpenAI API** [workaround_required]: OpenAI and Anthropic geo-block Hong Kong IP addresses; connect via a VPN server in Singapore, Japan, or Taiwan, or use a Singapore-routed eSIM. ([Guide](https://doesitworkin.com/hong-kong/chatgpt))
- **Travel eSIMs & Real-Name Registration** [conditional]: Local Hong Kong SIMs and 3HK plans require passport real-name registration (RNR) before activation; foreign data-only roaming eSIMs often skip HK RNR. ([Guide](https://doesitworkin.com/hong-kong/esim-real-name))
- **Google Maps, Gmail, YouTube & WhatsApp** [works]: Works at full speed on all Hong Kong Wi-Fi networks and mobile carriers with accurate GPS coordinates.
- **Octopus Card & Contactless Visa / Mastercard on MTR** [works]: MTR turnstiles, buses, and Star Ferry now accept foreign contactless Visa/Mastercard directly alongside the Octopus for Tourists iPhone app.
