China eSIM & Internet: Google, WhatsApp and Local Apps

A travel eSIM can give you mobile data in China and access to Google and WhatsApp, provided the plan uses an overseas internet connection. You can also register Alipay and DiDi with a foreign phone number, so getting a Chinese SIM is optional for those services.

If your existing mobile plan includes roaming in China, that is another way to stay connected. The useful distinction is what the connection lets you access, and whether you need a local number.

Google and WhatsApp in China

Google, Facebook and YouTube are blocked on mainland China's internet. A local SIM or ordinary hotel Wi-Fi uses that connection.

Some travel eSIMs work differently: they connect to a Chinese mobile network but send internet traffic through an overseas connection. For example, Airalo says its China eSIMs use this route, allowing access to Google and WhatsApp without a separate VPN. That is a feature of those plans, rather than something the word “eSIM” promises.

The difference shows up when you switch to Wi-Fi. An eSIM's overseas connection only applies to its mobile data; it does not carry over to the hotel network. If an app works on your eSIM but stops loading on Wi-Fi, the change of connection may explain it.

When comparing plans, look for an explicit statement about access to the services you use in China. “Unlimited” also deserves a closer look: some plans reduce speeds after a daily high-speed allowance. Your phone needs to support eSIM and be unlocked for another carrier's plan.

Using your own number in China

You can register Alipay with a foreign mobile number, and DiDi Greater China also supports foreign numbers and international credit cards. You do not need a +86 number just to pay or book a ride through these services.

A data-only eSIM does not include a phone number for calls or SMS. On a phone that supports two active SIMs, your usual line can stay available for verification texts while the travel eSIM provides data. Those texts still arrive through your usual carrier, whose roaming service and charges apply separately.

A mainland SIM becomes useful if you need local calls or a particular service requires a Chinese number. Foreign visitors can apply at China Mobile, China Unicom or China Telecom service offices with a passport. The line must be registered in your name.

Maps, payments and rides

For getting around, Amap — also called Gaode — now has an English version with local search and route planning. Its main map services can be used without logging in. It is a useful option alongside the apps you already use, especially when your connection cannot reach Google.

Alipay covers more than payments: you can also book a ride from inside the app. If you already use it, a separate ride-hailing app is optional. DiDi Greater China is another option if you prefer a dedicated app.
