On ordinary mainland networks and most hotel Wi-Fi, Google, WhatsApp, Instagram and similar apps are restricted. An international travel eSIM often routes cellular data outside the mainland, so those apps work on your phone’s mobile data — and often stop working when you join hotel Wi-Fi. A local Chinese SIM typically will not reach them. Install and test your plan before you fly, and use Amap, not Google Maps, for directions.

Key facts
| Restricted on mainland networks and typical Wi-Fi | Google services, WhatsApp, Instagram, Facebook, X and similar — this is a network fact |
|---|---|
| What still works there | WeChat, Alipay, Amap, DiDi |
| International travel eSIM | Often roaming, so cellular data may reach familiar apps; experience varies by plan |
| Local Chinese SIM | Fine for local apps; not, by itself, a path to restricted foreign apps |
| Hotel Wi-Fi | Usually a mainland connection, even if your eSIM’s cellular data is not |
| Maps | Use Amap. Google Maps is a poor primary map in China even when it opens |
You need a data plan that actually connects, and a clear idea of which apps the mainland network will not carry. Those are two different problems.
The actual problem
On ordinary mainland Chinese mobile networks and on most hotel or café Wi-Fi, many familiar services — including Google Search, Gmail, YouTube, WhatsApp, Instagram, Facebook and X — are restricted. That is a fact of the network, not a rumour. WeChat, Alipay, Amap (高德地图) and DiDi work on those same networks, which is why they belong on your night-before list.
Your job is not to “hack” anything. It is to arrive with a data plan that works, a map that works, and a clear idea of which apps will need a different path.
International eSIMs versus a local Chinese SIM
A travel eSIM bought from an international provider often works as roaming: your data is routed via the provider’s network outside the mainland. Travellers report that, on that cellular data, familiar apps often work without extra software. Two catches come up again and again in traveller discussions, and they match how the routing works:
- The moment you join hotel or café Wi-Fi, you are usually back on a mainland connection, and the restricted apps stop working. Switching back to cellular data (and turning Wi-Fi off) is the simple test.
- A locally bought Chinese SIM or eSIM (China Mobile, China Unicom, China Telecom) is typically a mainland connection. It is fine for WeChat and maps; it will not, by itself, make restricted foreign apps work.
We do not recommend a single brand. Experience varies by phone, by plan, and by month. Read recent reviews for the exact plan you are buying, confirm that your phone is unlocked and supports eSIM, and install and test the eSIM before you fly — some provider apps are themselves hard to reach from inside the mainland. Check whether the plan includes Hong Kong and Macao if you will cross the border, and whether tethering is allowed if you want to share data with a laptop.
Roaming on your home SIM
If your home carrier offers China roaming at a price you can live with, it is the least fiddly option: same number, same SMS for bank codes. Ask the carrier three things: whether China is included, the daily cap, and whether data is routed in a way that reaches the apps you need. SMS for Alipay or WeChat verification must actually arrive — some roaming setups delay or drop it.
Maps, mail and messaging
Google Maps is a poor primary map in China, even when it opens. Coverage and directions are often out of date. Use Amap (高德地图), which has an English interface, or Apple Maps, which many visitors find adequate. Save your hotel and first dinner as favourites, and keep a Chinese address on a driver card.
For mail and chat: if your eSIM’s cellular data reaches Gmail and WhatsApp, fine. Also be ready to use WeChat, because hotels, ticket desks and small businesses will want to message you there. Set WeChat up at home.
Hotel Wi-Fi, laptops, and tools you install at home
Hotel Wi-Fi is convenient and usually restricted in the same way as a local SIM. If you need a familiar service on a laptop, a common approach is to tether from a phone whose cellular data already works, if your plan allows it. Some travellers also install, before they leave home, a tool that their own country allows them to use, so that hotel Wi-Fi is usable for mail. We do not recommend a product, a setting, or a workaround: what works changes, some tools are unreliable, and you are responsible for following the law of your home country and of China.
Whatever you use, the unfashionable advice is the useful one: download it, log in, and test it before you fly. Keep offline copies of tickets, hotel addresses and maps. Do not rely on a single path.
Frequently asked questions
Do I need a VPN in China?
It depends on your data path. On some international eSIMs, familiar apps already work on cellular data and you may not need anything else on the phone. Hotel Wi-Fi is usually restricted. If you install any tool, do it at home, and follow the laws of your home country and of China. We do not recommend a product.
Will WhatsApp and Gmail work on an eSIM?
Travellers often report that they do, on international roaming eSIMs, over cellular data. They often do not, on hotel Wi-Fi or on a local Chinese SIM. Test before you rely on it, and keep WeChat as a fallback.
Does Google Maps work in China?
It may open, but it is unreliable for places and directions. Use Amap (高德地图) or Apple Maps.
Which eSIM should I buy?
We do not recommend a single brand. Read recent reviews for the exact plan, confirm your phone supports eSIM, check Hong Kong and Macao coverage if you will cross the border, and install it before you fly.
