What is an eSIM and how does it work in China
An eSIM (short for embedded SIM) is a digital version of a traditional SIM card built directly into your phone. Instead of inserting a physical card, you simply scan a QR code or sign up online with your chosen provider to get connected.
In China, eSIMs work just like anywhere else, but with one key difference: international eSIMs connect through foreign carriers that partner with Chinese networks such as China Mobile and China Unicom. This allows travelers to get reliable 4G and 5G coverage without needing a local SIM or Chinese ID.
Here’s how it works:
- Buy and download your eSIM plan before your trip.
- Install the eSIM using the QR code or app while connected to Wi-Fi.
- Activate on arrival, and your phone will automatically connect to the local partner network.
- Start browsing instantly without the need to change your number or visit a store.
For travelers heading to China, eSIMs are the easiest way to stay online. They are simple, fast, and ready to use the moment you land.
What to know before buying an eSIM in China
You can use international eSIMs in China, but local Chinese eSIMs are limited to residents. For digital nomads and travelers, eSIMs are the most reliable way to stay connected across mainland China without visiting a store or registering a local SIM.
Here’s what to keep in mind before you buy:
- VPN access: Some Western sites and apps (Google, WhatsApp, Instagram) are restricted in China. You may need a VPN to access them.
- Local restrictions: Chinese eSIMs are usually available only to residents with a local ID.
- Coverage: International eSIMs connect to major Chinese carriers like China Mobile and China Unicom for reliable 4G and 5G speeds.
- Setup tip: Install and activate your eSIM before flying, while you’re still on Wi-Fi.
With the right eSIM, you can start using data the moment you land. No kiosks or paperwork needed, and no roaming surprises to be expected.

How to choose the right eSIM for China
Choosing the right eSIM depends on how you travel and how much data you use. Both Holafly and eSIM4Travel are solid options, but each suits slightly different needs.
Here are a few things to consider before buying:
- Data usage: If you use your phone mainly for maps, messages, and browsing, a small plan from eSIM4Travel might be enough. For heavy data use like video calls or remote work, Holafly’s unlimited data can be more convenient.
- Trip length: Short trips often benefit from flexible, low-cost plans. Longer stays are usually better with fixed-duration or unlimited options.
- Device compatibility: Most recent iPhones, Pixels, and Samsung models support eSIM, but it’s always worth checking your phone’s settings before buying.
- VPN and accessibility: Some Western apps and websites are restricted in China. If you rely on them, make sure your eSIM works smoothly with a VPN connection.
- Support and setup: Pick a provider that offers clear installation guides and responsive customer support, ideally with live chat available while you travel.
Taking a few minutes to think about your usage and travel plans can save you from data issues or extra costs during your trip.

Setting up your eSIM for China is simple if you do it before you travel. Most providers send your eSIM by email, along with a QR code or link and setup instructions. Here’s what to do step by step:
