China trip guide
How do you stay connected to work on a business trip to China?
Start with your company’s IT team, because many companies have their own VPN and rules for China trips. Gmail, Google Docs and Drive are blocked on Chinese networks, and Microsoft says its services can be slow from China, so set up your work apps at home. For local contacts, plan on WeChat.

Ask your IT team first
Many companies have a plan for staff in China. Microsoft describes companies that send their China users’ traffic through a company VPN and private network links, to avoid the congested links out of China. Some organisations also lend laptops for travel abroad.
So ask before you go:
Does the company VPN work from China?
Is there a travel laptop?
Are you allowed to add your own VPN to a work laptop?
Your work apps in China
- Google Workspace
Gmail, Docs and Drive are blocked in mainland China. You need a way past the block.
- Microsoft 365
Microsoft says the links between China and the rest of the internet are congested, which hurts large files and calls. From a hotel, without a company connection, it can be slow. Microsoft suggests the desktop apps, such as Outlook, Teams and OneDrive, over the web versions, because they keep a copy of your work.
- Teams calls
Microsoft has set up a better route with Chinese telecoms for Teams calls and meetings over the local internet. Chat and files don’t get it. If your company has audio conferencing, you can also dial in to a meeting by phone.
- Slack
Its apps were taken out of app stores in mainland China in March 2024. Apps you already have keep working, so install and update Slack at home.
Your devices and data
Canada’s travel advice says authorities in China may review what’s stored on your devices, and that communications may be monitored at any time. MIT advises its travellers to take the least data on the fewest devices they can, and lends laptops for trips abroad. Check what your company expects.
Trade fairs such as the Canton Fair
Suppliers and partners in China use WeChat, so set it up at home, where sign-up is easier. For the April 2026 Canton Fair in Guangzhou, the city ran a service area for the fair in the “OneStop” WeChat mini program, with a section for international visitors on transport, payment and daily services.
Where Tunnelz fits
Tunnelz is for your own Mac. It sets up your own server, not shared with thousands, and the Smart route sends Chinese sites direct, so WeChat and local sites stay fast. If your server is ever blocked, Replace Server can set up a new one in minutes, as long as the app can reach Vultr. In China that may take eSIM data or another network (how). If your company has its own VPN or rules for China, follow those first.
