What Devs Need to Know Before Visiting China in 2026
Traveling to China as a developer brings unique friction. It is not just the Great Firewall. The real issues are small. A QR code at a restaurant will not work. A metro gate will reject your foreign card. Hotel Wi-Fi will drop your connection to Google.
Here is your survival guide for 2026.
Visa Rules Many countries like the US, UK, and most of the EU enjoy 30-day visa-free transit. You only need an onward ticket. Check the specific rules for your nationality one week before you book.
Payments China runs on Alipay and WeChat Pay. Cash is hard to use at small shops. Foreign cards work at big hotels but fail at local food stalls.
Use these steps to fix this:
- Install Alipay and use the Tour Card feature.
- Install WeChat Pay and enable International mode.
- Verify your identity with your passport and a selfie before you leave.
- Link your Visa or Mastercard to these apps.
Two tips for payments:
- Keep top-ups under 200 RMB to avoid a 3% fee.
- WeChat Pay limits reset at midnight Beijing time.
Internet and Connectivity If your home carrier has a China roaming plan, use it. Your traffic will route through Hong Kong. This means Google, GitHub, and Slack will work.
If you do not have roaming, you have three choices:
- Buy an eSIM from China Unicom HK or 3HK. This routes through Hong Kong to keep your apps working.
- Install a VPN with a stealth protocol before you land. Do not wait until you arrive because VPN websites are blocked.
- Use local alternatives. Apple Maps works well in China. Use Outlook instead of Gmail and Telegram instead of Slack.
Transport The high-speed rail is the best way to travel. You can go from Beijing to Shanghai in about 4 hours. There are no long security lines. You simply tap your passport at the gate.
Use Trip.com or the 12306 app to book tickets. Buy them at least one day in advance.
