Do you need to buy an eSIM for China? This is a question many travelers ask when preparing for a trip to a country with a strictly controlled internet system. An eSIM is considered a solution that helps you connect quickly, access Google, Facebook, and Zalo stably without having to install a complicated VPN. In this article, you’ll clearly understand why you should use an eSIM, how to use it, and how to choose the right plan for your trip.

Do you need to buy an eSIM for China?
Do you need to buy an eSIM for China? The answer is yes — it’s highly recommended. China has fairly strict internet controls, so many platforms like Google, Facebook, and YouTube are restricted when using the local network. This makes communication, information searching, and using familiar apps more difficult.
Using a China eSIM helps you get online as soon as you land without having to remove a physical SIM. You can still access familiar apps stably and conveniently. This is an optimal solution, especially suitable for travelers on short trips or those who need continuous internet.
Can you use a Vietnamese SIM in China?

The answer is YES, you can absolutely bring your Vietnamese SIM (Viettel, Vinaphone, Mobifone…) to China. However, you need to register international roaming before departure. This is a way to keep your phone number for communication while abroad. Although convenient, this option still has some major limitations:
- Extremely expensive cost: Data roaming charges are very high, and large costs can quickly arise after a short period of use.
- Unstable speed: The connection depends on the local network, so it may be spotty and disrupt the experience.

Notes when using an eSIM in China
To ensure the eSIM works stably and avoid errors during use, you need to understand the notes below. These are important steps before and while using a China eSIM. Careful preparation will help you stay connected without interruption.
- Check whether your phone supports eSIM
Not every device supports eSIM. iPhone XS/XR and later, Samsung S20/Note 20/Z Fold/Flip, and Google Pixel 3 and later all support it. You can dial *#06#, and if an EID code appears, your device supports eSIM. - Make sure your phone is an international version: eSIM does not work on carrier-locked phones or devices using a SIM adapter. If your phone is not an international version, you won’t be able to activate it. So check in advance to avoid wasting time.
- Do not delete the eSIM after installation: Each QR code can only be scanned once. If you delete the eSIM, you won’t be able to reinstall it with the old code. If there is a problem, contact support instead of deleting it yourself.
- Install while you have stable WiFi: You need internet to scan the QR code. It’s best to install it before flying or at the airport. Avoid waiting until you are in China to install it because you may not have internet then.
- Remember to turn on Data Roaming: When you arrive in China, you must turn on Data Roaming for the eSIM. If you don’t, your phone won’t have internet even though the eSIM is already installed. This is the most common mistake people make.
