|---|---|
| Mobile Data | China eSIM |
| Calls | Primary SIM |
| SMS | Primary SIM |
| Data Roaming on China eSIM | ON |
| Data Roaming on Primary SIM | OFF |
| Automatic Data Switching | OFF |

APN Settings for China eSIM
Most phones configure APN settings automatically. If mobile data does not work after arrival in China, enter the APN manually.
| Field | Value |
|---|---|
| APN | data.esim |
| Username | Leave blank |
| Password | Leave blank |
| Authentication | None |
Should Network Selection Be Automatic?
Yes. Network Selection should usually stay on Automatic. This lets your phone connect to an available supported network without forcing one operator manually.
If mobile data does not work, first check Data Roaming, Mobile Data selection, APN settings and whether your plan includes China before changing network manually.
Best Network for Maps and Translation Apps
Maps and translation apps usually need stable mobile data more than extremely high speed. In cities such as Beijing, Shanghai, Guangzhou, Shenzhen, Xi’an and Chengdu, major networks should usually be suitable for maps, translation and travel apps.
For rural trips, mountain areas, national parks or remote regions, download offline maps and save important addresses before leaving major cities.
Best Network for High-Speed Rail Travel
China’s high-speed rail routes often pass through cities, tunnels, rural areas and station zones. Mobile data may work well in many sections, but signal can vary during long train journeys.
Before boarding, save your hotel address, ticket details, translation phrases and offline maps.
Best Network for Remote China Travel
If your trip includes Tibet, rural Yunnan, mountain areas, remote national parks or smaller villages, expect mobile data to vary. Even the strongest network cannot provide stable internet in every remote location.
Use mobile data where available, but do not rely on it as your only travel backup in remote areas.
Does WhatsApp Work on China Mobile Networks?
WhatsApp may not work normally on local Chinese internet networks because some apps and services can be restricted. A China eSIM provides mobile data, but app access can depend on network routing, local restrictions and your specific plan.
Your WhatsApp account can remain linked to your existing phone number, even if your China eSIM is data-only.
