China has a national internet filtering system that blocks a large number of foreign websites and apps. No matter which SIM card you use, the following services are blocked at the network level:
- Google (Search, Maps, Gmail, YouTube, Google Drive)
- Facebook and Messenger
- Twitter / X
- Snapchat
- Most foreign news sites (BBC, New York Times, Reuters)
This guide covers two common solutions: eSIM and local SIM card + VPN.
Option 1: eSIM — International Roaming Ready on Arrival
What Is eSIM
eSIM is an embedded digital SIM card. It requires no physical card slot — you manage and switch carriers entirely through software.
Key Features
- Access international apps in China without a VPN
- No passport required to purchase a travel eSIM; setup is quick and simple

Option 2: Local SIM Card + VPN — Budget-Friendly Local Option
Why Does a Local SIM Card Need a VPN?
Due to China’s internet firewall (GFW), a local SIM card only gives you access to Chinese apps (WeChat, Alipay, Amap, etc.). To use Google, Instagram, and other international services, you will need a VPN.
How to Get a Local SIM Card
Have your passport ready before you go.
- Buy online: You can order a SIM card online. For example, China Unicom offers travel SIM cards with international shipping. You can also find well-reviewed options on Amazon.
- Airport counters: After landing, ask staff whether SIM cards are available at the airport. Airports with SIM card counters include:
- Beijing Capital International Airport (PEK)
- Beijing Daxing International Airport (PKX)
- Shanghai Pudong International Airport (PVG)
- Guangzhou Baiyun International Airport (CAN)
- Chengdu Tianfu International Airport (TFU)
- Carrier stores in the city: Search for any of the following carriers on your map app to find the nearest store:
- China Unicom
- China Telecom
- China Mobile
VPN
This guide does not recommend specific VPN products — choose one with good reviews. Make sure to download and test your VPN before arriving in China, as most VPN websites are also blocked within the country.
FAQ
Will my Chinese SIM card still work after leaving China?
It depends on your plan. Most local Chinese SIM cards stop working or become very slow once you leave the country. Some China Unicom tourist plans include a small amount of roaming data in neighboring countries like Japan, South Korea, and Thailand. If you plan to visit multiple countries in one trip, ask the carrier before purchasing.
