Preparing Your Tech for a Business Trip to China

A business trip to China tests your tech setup fast. Google services are blocked. Several Western apps load slowly or not at all. Payments work differently. Security risks also rise. Start preparing two to four weeks before departure.

What Changes When You Land

China filters internet traffic at the network level. Google Search, Gmail, Drive, YouTube, WhatsApp, Instagram, Facebook and X are blocked or unreliable. Slack, Zoom and Microsoft Teams often work, but speed varies by city and carrier.

Ask a local colleague to test your core tools before you fly. Then build your plan around what fails.

Set Up a VPN Before You Leave

A reliable VPN for China is the first item on your checklist. VPN websites and app store listings are blocked inside the country. Install and configure everything at home.

Use this order:

• Install two VPN apps so one can back up the other.
• Sign in on every device you will carry.
• Test each connection protocol, including obfuscated modes.
• Enable the kill switch and DNS leak protection.
• Save offline installers and account details.

Some networks throttle standard WireGuard traffic. Obfuscated modes often hold up better. Rules on VPN use are strict in China. Ask your legal or compliance team what applies to your company.

Choose Your Data Connection

Your connection type affects what you can reach. International roaming routes traffic through your home carrier. That often avoids local filtering, but rates can be high. An eSIM with home-routed data works the same way.

A local SIM is cheaper. It requires your passport for real-name registration, and traffic is filtered. Hotel Wi-Fi is filtered too. Treat it as untrusted. Use your VPN and avoid sensitive logins on it.

Harden Your Devices

Assume any network you use may be monitored. Reduce what a lost or inspected device can expose.

• Carry a clean loaner laptop with only the files the trip needs.
• Turn on full disk encryption with BitLocker or FileVault.
• Update the OS, browser and all apps before departure.
• Back up your data and leave the backup at home.
• Use hardware security keys and pack a spare.
• Set up authenticator apps, since SMS codes can arrive late.
• Turn off Bluetooth and Wi-Fi auto-join.
• Use a privacy screen on flights and in lobbies.

Never leave devices unattended in hotel rooms. Use the room safe, or keep them on you.

Prepare Apps and Payments

Mobile payment dominates Chinese cities. Cash is used less every year. Set up the essentials at home.

• Install WeChat and register your account before departure. Most business contacts use it.
• Link a foreign card to Alipay or WeChat Pay, then run a test payment.
• Download offline maps. Apple Maps works. Amap and Baidu Maps offer better local detail.
• Install offline translation packs.
• Carry a physical card and some cash as backup.
  
  

Plan for Power and Hardware

China runs on 220V at 50Hz. Outlets are Type A, C and I. Pack a universal adapter and check that your chargers accept 100 to 240V.

Keep power banks in carry-on bags only. Stay under 100Wh per unit. Check your airline's rules, since Chinese carriers may require certified power banks. Bring spare cables. Replacement gear costs time you will not have.

Run a Dry Test Before You Fly

Test your setup three days before departure. Connect through your VPN on home Wi-Fi. Open email, cloud storage, video conferencing and every tool you need for meetings. Log each failure. Fix it or replace the tool.

Confirm that your file access works. Microsoft 365 and OneDrive generally work in China. Google Drive does not. Save key documents locally in encrypted archives.

Print hotel addresses in Chinese, meeting locations and key contacts. Phones die. Paper does not.

Check Legal and Advisory Guidance

Read the U.S. State Department's China travel advisory before you book. It covers exit bans, arbitrary enforcement of local laws and detention risks for foreign business travelers.

Enroll in the Smart Traveler Enrollment Program for alerts. Brief your team on emergency contacts and escalation steps. Share your itinerary with your security lead.

Secure Your Devices After the Trip

Treat returning devices as untrusted. Reimage the loaner laptop. Change every password used abroad. Revoke active sessions and review account logins. Scan phones for unusual apps or profiles. Log any incident with IT.
