Most people notice it within an hour of landing in mainland China. The phone shows full signal, the hotel Wi-Fi is connected, and yet the apps they use every day simply refuse to open. Search spins forever, mail never syncs, messengers sit on "connecting".

Nothing is broken. Those services are hosted outside the country, and cross-border links treat different kinds of traffic differently. This article lays out plainly which services do not work in mainland China, which ones carry on as normal, and what to prepare before departure so that work and family contact stay stable.

What generally will not connect

On an ordinary local connection these are effectively unreachable:

  • Everything Google — Search, Gmail, Drive, Calendar, Maps, Translate, YouTube
  • Social and messaging — WhatsApp, Instagram, Facebook, X (formerly Twitter), Telegram, Snapchat, Discord
  • Reference and media — Wikipedia, Reddit, Netflix, Twitch
  • AI tools — ChatGPT, Perplexity
  • Foreign news — BBC, The New York Times, The Guardian, The Wall Street Journal, Bloomberg

Estimates of affected domains run into the hundreds of thousands, so no list is ever complete. The useful question is not "is this app on a list" but "where are its servers".

What still works normally

The better news is that a large slice of ordinary work tooling is unaffected:

  • Apple — iMessage, FaceTime, App Store, iCloud, Apple Maps
  • Microsoft — Bing, Outlook, Office, Teams
  • Collaboration and development — Zoom, GitHub
  • Shopping and travel — Amazon, most hotel and flight booking sites

Put simply: if your workflow sits on Microsoft and Apple, the disruption is far smaller than if it sits on Google.

Why "I will sort it out when I arrive" fails

This is the classic traveller's mistake. The websites and app-store pages of most connectivity tools are themselves unreachable from inside the country. People land, open the download page, and find that the page will not load either.

Account recovery has the same trap. If your two-factor codes arrive in Gmail and Gmail will not connect, you are locked out of your own accounts. All of this has to be handled before you fly.

A pre-departure checklist

  • Install and test your connectivity tools before leaving, and confirm you can sign in
  • Move two-factor delivery to SMS or a mailbox that works locally — do not depend on Gmail alone
  • Download offline maps in advance (Apple Maps works locally, Google Maps does not)
  • Set up a fallback contact channel: iMessage, FaceTime or WeChat
  • Copy important documents out of Google Drive into OneDrive or local storage
  • Save emergency phone numbers, not just social-app handles

Why connection stability is the real issue

For anyone travelling on business the question is rarely "can I open this website". It is whether the connection is predictable. A video call that drops mid-sentence, mail that arrives half an hour late, a payment page that times out — these hit your work directly.

A VPN (Virtual Private Network) builds an encrypted tunnel between your device and a server. Data is encrypted before it leaves the device, so other people on the hotel or airport Wi-Fi cannot read it, and neither can whoever runs that network. For a business traveller who lives on public Wi-Fi, that is worth having in any country.

When choosing a provider, three things matter: how stable the connection is, how close the servers sit to where you are (closer means lower latency), and whether the provider keeps logs. Orris VPN runs nodes in Asia on a no-logs policy — plans and pricing are listed openly.

Conclusion

In mainland China the whole Google suite, the main social apps and most foreign news sites will not connect, while Apple services, Microsoft tools, Zoom and GitHub carry on as usual. The one rule that matters: prepare before you fly, because the download pages you would need are unreachable once you are there.

Twenty minutes of preparation is what stands between a smooth trip and losing contact with your work and your family.
