Using Your eSIM in China

What the Great Firewall blocks, and why a travel eSIM behaves differently there.

Using Your eSIM in China

China filters internet traffic nationally. Google — including Gmail and Maps — plus Instagram, Facebook, X, WhatsApp and many news sites are blocked on local connections such as hotel Wi-Fi.

A travel eSIM connects through roaming rather than a local Chinese carrier, and travelers often report reaching their usual services this way. We cannot promise it. The behavior depends on the network's routing, which we do not control and which can change without notice.

Practical Advice

Set up before you fly. Install the eSIM while you still have unrestricted internet; it activates on its own when it connects to a local network on arrival. Downloading anything once you have landed may be impossible.

Do not rely on hotel Wi-Fi for anything you need — it is subject to the full local filtering.

Keep an offline map of your destination and screenshots of your bookings.

Have a Chinese payment app ready if you can. Cash and foreign cards are accepted far less widely than travelers expect.

If Services Are Blocked Anyway

Confirm you are actually on eSIM data and not on Wi-Fi — this is the usual explanation. If you are on eSIM data and still blocked, contact us with the specific service and we will check the routing for your plan.
