Why Use an eSIM with VPN to Connect to the Internet When Traveling in China?

Are you planning a trip to China? Whether you're going for leisure or business, you’re probably aware that internet access in China is highly restricted due to the implementation of the Great Firewall of China, also known as the Golden Shield.

Although you can still access the internet in the country, many apps and websites are blocked. While locals are used to this, tourists and foreign workers will need to adapt. So, if you’re planning to get a travel eSIM for your trip to China, it’s strongly recommended to also get a VPN to bypass the limitations. Here's why and how to do it.

How Can You Access the Internet While Traveling in China?

When traveling abroad, you have several options to stay connected. The same goes for China, despite the Great Firewall!

Local SIM Cards

You can get a prepaid Chinese SIM card at numerous stores throughout China, including at the airport upon arrival. This will give you a local Chinese phone number with a plan that includes calls, SMS/MMS, and a certain amount of data. These plans are often very affordable but come with some downsides. First, expect to spend at least an hour in-store to choose a plan and set up your phone, likely in Mandarin. Also, you’ll need to remove your regular SIM, meaning you won’t be reachable on your usual number.

Public Wi-Fi Networks

There are many public Wi-Fi networks in China—train stations, airports, malls, restaurants, etc. While free, these networks are known to be insecure, which is especially problematic in a country where online activity is heavily monitored. This makes public Wi-Fi a poor option when it comes to protecting your personal or business data.

Pocket Wi-Fi Devices

Most Chinese telecom operators offer tourists the option to rent pocket Wi-Fi devices. These small gadgets, equipped with a SIM card, turn a 4G or 5G connection into Wi-Fi, like a mobile router. It’s handy if you're sharing a connection with other travelers or multiple devices, but it's also bulky and needs regular recharging.

Travel eSIMs

Travel eSIMs use embedded SIM technology to deliver instant international data plans. These let you enjoy a 4G or 5G internet connection on your smartphone while keeping your regular number and without needing any extra hardware.

To use one, just visit a provider of international eSIMs like UPeSIM, choose a suitable plan, and activate it immediately using a QR code. It’s the most convenient solution for travelers who want to use their phone just like at home, no matter the destination.

How Is Internet Access Restricted in China?

Recently in the news for limiting online access for minors, China has one of the world’s strictest internet policies. But what exactly is the Chinese Golden Shield?

What Is the Chinese "Great Firewall"?

The Great Firewall is a comprehensive system for blocking, filtering, and monitoring internet traffic across China. It originated in the late 1990s as a political decision to block foreign web content deemed harmful to Chinese users or national stability.

By blocking IP addresses and DNS servers, filtering URLs, and deeply inspecting data packets, this system can restrict access to websites, detect sensitive keywords, and even throttle the connection of users deemed "suspicious." This affects many websites and apps you probably use every day.

Which Websites and Apps Are Blocked in China?

Chinese users—and visitors—can’t access most major Western platforms: Google, Facebook, Instagram, X, WhatsApp, Messenger, YouTube, Netflix, Twitch, Spotify, Slack, Trello…

While alternatives like Baidu, WeChat, and Youku are available, these platforms are also closely monitored by authorities.

What Does This Mean for Foreign Travelers?

The Great Firewall doesn’t only affect Chinese citizens—it affects everyone visiting the country. You won’t be able to access your social media, email, messaging apps, or streaming services throughout your stay. That means you could be completely unreachable, and unable to access flight tickets, hotel bookings, or travel documents. So even if you plan to print everything, you must have a way to bypass China’s internet restrictions.

How Can a VPN Bypass Internet Restrictions in China?

One of the easiest and most secure ways to get around the Great Firewall is to install a VPN on your devices. Here’s how it works:

What Is a VPN?

VPN stands for Virtual Private Network. It’s a tool that allows you to browse the internet securely and privately, with encrypted data and a masked IP address. VPNs are commonly used to secure public Wi-Fi, avoid tracking, and access geo-restricted content (like your streaming catalog or online games). That’s exactly why it’s recommended for travel in China!

How Does a VPN Work?

A VPN encrypts your data and routes it through a remote server. This prevents tracking and hides your IP address, replacing it with one from the server you connect through. You can even choose the server location, letting you appear to be in another country and thus access the content you’re used to—even if your real IP address is in China.

Is It Legal to Use a VPN in China?

China officially allows only a handful of government-approved VPN services. Most commercial VPNs are technically banned. While foreigners aren’t typically punished for using a VPN (since everyone does), it’s best to stay discreet and pick a reputable VPN provider.

What’s the Best VPN for China?

Avoid free VPNs in China—they are more likely to be blocked. Instead, go with a trusted provider like NordVPN, ExpressVPN, Astrill, or Surfshark, which regularly update their servers to stay ahead of China’s filters. For ultimate peace of mind, choose a travel eSIM for China that already includes a VPN!

Why Is an eSIM with VPN the Best Option for Traveling in China?

Rather than purchasing an eSIM and VPN separately, it’s smarter to choose an eSIM that already includes VPN protection. This way, you get the benefits of both in one solution.

Instant Internet Access

With a travel eSIM, you can install it the day before or the day of your departure and enjoy immediate internet access upon arrival, with no airport hassle.

A Private and Secure Network

eSIM internet access is more secure than public Wi-Fi. Even without a VPN, your connection is less likely to be monitored or hacked.

No Need to Install a VPN

You don’t need to sign up for or install a VPN separately on all your devices. Since the eSIM already includes a VPN, your connection is secured automatically, both on your smartphone and for any shared hotspot use. You won’t need to tweak any settings to access your usual apps and content.

What’s the Best eSIM for Traveling to China?

Unsurprisingly, the best eSIM for China is one with a built-in VPN! That’s why UPeSIM offers a China eSIM with VPN across all plan durations.
