# Does ChatGPT Work in China, and How to Access It Safely?

Status: **WORKAROUND_REQUIRED** | Last verified: 2026-11-11

> **Verdict:** ChatGPT, Claude, and Gemini are double-blocked in China: blocked by the Great Firewall AND geo-blocked by OpenAI/Anthropic on both mainland Chinese and Hong Kong IPs. To use ChatGPT in China without a VPN, you must use an eSIM whose exit node is in Singapore (such as Airalo Chinacom), not Hong Kong.

## Official Claim vs. Verified Reality

- **Official claim:** Travel eSIM providers say their China eSIMs 'unblock all Western apps and websites.'
- **Verified on the ground:** Many China travel eSIMs route traffic through Hong Kong (3HK or CMLink). While a Hong Kong IP unblocks Google, YouTube, and WhatsApp, OpenAI and Anthropic block Hong Kong IP addresses too! If your China eSIM exits in Hong Kong, opening ChatGPT will return an 'Unsupported Country or Territory' error unless you layer a VPN set to Singapore, Japan, or the US on top of your eSIM.

## Before You Fly (Pre-Departure Checklist)

- Choose a China or Asia regional eSIM that routes through Singapore (Singtel/StarHub) rather than Hong Kong (3HK).
- Install Proton VPN or ExpressVPN before departure so that if your eSIM or hotel connection exits via Hong Kong, you can hop to a Tokyo or Singapore VPN server.
- Keep the ChatGPT and Claude iOS/Android apps logged in before boarding; re-authenticating via Cloudflare Turnstile on a flagged IP is much harder than using an existing session.

## Practical Limits & Failure Modes

- Using a residential proxy or shared low-reputation VPN IP with Claude or OpenAI can trigger automated account suspension; stick to reputable Singapore eSIM roaming IPs or clean VPN servers.
- Apple Intelligence features that rely on OpenAI integration are also unavailable on Hong Kong and mainland China IP addresses.

## Recommended Providers

- **[Airalo](https://doesitworkin.com/go/airalo)** — *Best Singapore-routed China eSIM for ChatGPT* ($4.50 / 1 GB (7 days)): Airalo's Chinacom and Asialink plans route via Singtel (Singapore), which is on OpenAI and Anthropic's supported countries list. *(Note: Verify your IP location at ipinfo.io after landing; if a secondary carrier profile routes via HK, toggle to the Singapore APN/carrier.)*
- **[Proton VPN](https://doesitworkin.com/go/protonvpn)** — *Best VPN to hop from a Hong Kong exit to Japan/Singapore* (Free tier (5 countries); Plus from $4.49 / mo): If you use a 3HK or Holafly eSIM that exits in Hong Kong, running Proton VPN on top of your cellular data works at full speed because the Hong Kong exit has no Great Firewall blocking the VPN handshake. *(Note: Connect to Japan or Singapore servers for the lowest latency.)*

## Frequently Asked Questions

### Why does my China eSIM open Google and Instagram, but ChatGPT says 'Unsupported Country'?

Because your eSIM is routing through Hong Kong. Hong Kong has no Great Firewall (so Google works), but OpenAI blocks Hong Kong IP addresses. Turn on any standard VPN set to Singapore or Japan over your eSIM data, and ChatGPT will work immediately.

### Do normal VPNs work if I run them on top of a Hong Kong-routed China eSIM?

Yes! Because the eSIM already tunnels your traffic past the mainland Great Firewall to Hong Kong, a standard VPN (like NordVPN, Surfshark, or Proton VPN) can connect from Hong Kong to Tokyo or Singapore without interference.
