Can Zalo Be Used in China? Tips for Stable Use
Before heading to China, many people wonder whether Zalo can be used in China and how to avoid interruptions in communication. Sim PM helps you understand the reasons and how to use Zalo stably throughout your trip to China.
Can Zalo be used in China?
Can Zalo be used in China? The answer is no. Zalo cannot be used normally in China if the user connects to the internet through the country’s domestic network. When using a Chinese SIM, hotel Wi-Fi, airport Wi-Fi or cafe Wi-Fi, the Zalo app is usually unable to send messages, make voice calls, make video calls or sync notifications.
In practice, many people only realize this problem after arriving in China and suddenly losing contact with family and colleagues because Zalo does not work. This especially affects travelers, short-term business travelers, or Vietnamese students who use Zalo as their main communication channel.
Why can’t Zalo be used in China?
To clearly explain why Zalo cannot operate normally in China, it is necessary to look at the country’s specific internet management policy. China does not operate the internet in an open model like many other countries, but applies strict control mechanisms to manage information flow and cross-border data.
The Great Firewall internet censorship system
China operates a large-scale internet censorship system, commonly known as the Great Firewall. This system monitors, filters, and restricts access to online services whose servers are located outside China or that are not under the management of domestic authorities. As a result, many international platforms familiar to Vietnamese users are blocked or operate unstably.
Platforms not managed by China are restricted from access
Applications that are not part of China’s domestic technology ecosystem are generally not allowed to access the domestic network directly. This applies broadly to many foreign services, including social networks, search tools, and messaging apps. When users connect to the internet using a China SIM or domestic Wi-Fi, these platforms are restricted or completely disconnected.
Zalo is not part of China’s domestic app ecosystem
Zalo is a messaging app developed in Vietnam, does not have domestic servers, and is not among the platforms prioritized for operation in China. Because it is not part of the domestic app ecosystem, Zalo is not granted direct network access through China’s telecommunications infrastructure.
How to use Zalo in China
Although Zalo is blocked on the domestic internet infrastructure, users can still maintain communication if they choose the right connectivity solution. In practice, the questionCan Zalo be used in China does not only depend on the app, but on how you access the internet in China. Below are the two most common options today, along with an objective assessment to help users choose more easily.

VPN is a familiar option for people with technology experience. The principle of a VPN is to create an intermediate connection to route data outside China, thereby accessing blocked platforms such as Zalo. However, VPN use in China is not stable because many VPN services are restricted or blocked over time.
- Need to install and configure before traveling to China.
- Connection speed depends on VPN quality.
- Easily interrupted or may not work during peak hours.

What should you prepare to use Zalo stably when traveling to China?
