How to Use the Internet in China: Business Traveler’s Guide

If you’re planning a business trip to China — whether it’s for visiting factories, attending the Canton Fair, or meeting suppliers in Yiwu — staying connected to the internet is essential.

However, using the internet in China is quite different from other countries due to local restrictions and infrastructure. Apps like Google, WhatsApp, and Gmail may not work without the right setup.

This guide explains how foreign buyers and business travelers can access reliable internet in China, covering eSIMs, local SIM cards, portable WiFi, and VPN options to help you stay online and productive.

1. Why Internet Access in China Is Unique

China has one of the most advanced mobile networks in the world — 5G is available in almost every city — but international websites and apps are restricted under what’s known as the “Great Firewall.”

That means many services you use daily, such as Google Maps, YouTube, WhatsApp, and Instagram, are blocked.For foreign buyers, this can make communication and navigation difficult. You may need internet access not only to message suppliers but also to use translation tools, payment apps, and cloud storage.

That’s why it’s critical to plan your internet in China setup before you arrive.

2. Option 1: Use an International eSIM Before You Arrive

An eSIM (embedded SIM) is one of the easiest and fastest ways to get connected in China. You can buy and install it online before your flight, and activate it once you land.

Advantages:

● No need to visit a local store or show your passport.

● Keeps your original SIM active for business calls.

● Some eSIMs include built-in VPN access for unrestricted browsing.

How it works:

You’ll receive a QR code from your provider. Scan it to install the eSIM profile, and data access will activate automatically.

Popular eSIM providers for China: Holafly, Airalo, Nomad.

Each offers short-term data plans (3–30 days) with different speeds and coverage.

Tip: Install and test your eSIM and VPN before entering China, as many websites and app stores are blocked once you arrive.

3. Option 2: Buy a Local Chinese SIM Card

If you plan to stay in China for several weeks or months, a local SIM card is often more cost-effective. The three main carriers are China Mobile, China Unicom, and China Telecom.

What you’ll need:

● A valid passport for registration.

● An unlocked phone that supports Chinese network bands.

You can purchase SIM cards at airports, convenience stores, or official carrier shops in large cities.

Pros:

● Lower cost for long stays.

● Stable 4G/5G coverage almost everywhere.

Cons:

● International apps (Google, WhatsApp, etc.) remain restricted.

● Staff may not speak English in some locations.

Most foreign buyers choose China Unicom, as its frequency bands work best with international smartphones.

4. Option 3: Use a Portable WiFi (Pocket WiFi) Device

A portable WiFi device, also called a pocket WiFi, creates a personal hotspot you can share with multiple devices.

It’s a good solution for teams traveling together or for people using laptops and tablets frequently.You can rent one at airports, hotels, or online before your trip.

Advantages:

● Connect several devices at once.

● No need to change SIM cards.

● Some models include VPN service.

Drawbacks:

● Requires charging and carrying an extra device.

● Connection speed may drop if multiple users share it.

For factory tours or trade fairs, pocket WiFi helps you stay connected even when switching devices between meetings.

5. Option 4: Use Hotel or Public WiFi (with Caution)

Many hotels, cafés, and restaurants in China offer free WiFi, but these networks often require a Chinese phone number to verify access.

Moreover, public WiFi is not always secure, and your browsing may still be filtered.To protect sensitive business information, always use a VPN when connecting to public networks.

Also, avoid accessing confidential business accounts over open WiFi connections.

6. Do You Need a VPN in China?

If you need to use apps like Google Maps, Gmail, or WhatsApp, then yes — you’ll need a VPN (Virtual Private Network).

A VPN lets you securely connect to international servers and access blocked sites.However, keep these rules in mind:

● Download and activate the VPN before entering China.

● Choose reliable, paid providers with proven performance.

● Free VPNs are often unstable and may expose your data.

Using VPNs in China is a gray area for individuals — always choose trustworthy providers and use them responsibly.

7. Best Internet Setup for Business Travelers

For most foreign buyers visiting China for sourcing trips, the best solution is a combination of eSIM + VPN.

This setup gives you stable data, quick activation, and full access to communication tools.

Option	Best For	Pros	Cons
eSIM	Short trips, flexibility	Quick setup, no registration	More expensive for long stays
Local SIM	Long stays	Low cost, reliable coverage	Needs registration, no access to blocked sites
Pocket WiFi	Teams or laptops	Multi-device sharing	Extra device to carry
Hotel/Public WiFi	Occasional use	Free	Unstable, not secure

Pro Tip: Always keep your main SIM active to receive calls from your home country while using data from your eSIM or WiFi.

8. Pre-Trip Checklist: Stay Connected the Smart Way

Step	What to Do	Timing
1	Choose your preferred connection (eSIM, SIM, or WiFi)	1 week before travel
2	Purchase and install eSIM / VPN	3 days before flight
3	Test access to Gmail, WhatsApp, Maps	Before departure
4	Keep your original SIM active	During trip
5	Bring a portable power bank	Optional but useful

With the right preparation, you can focus on building supplier relationships instead of worrying about internet issues.
