China eSIM Guide: Networks, Local Apps and Hong Kong vs Mainland
Mainland China has excellent mobile coverage: high-speed rail lines, metro systems and even many rural areas are well served. What makes a China trip different is the apps. Daily life runs on Chinese apps for payments, maps, taxis and messaging, and many international services visitors rely on at home don't work the same way on mainland networks. Preparing your phone before you go matters more than which plan you buy.
Which networks China eSIMs use
Mainland China has three national operators: China Mobile, China Unicom and China Telecom. Among the wholesale China plans we track:
| Plan type | Networks | Where data exits |
|---|---|---|
| Roaming via Hong Kong | China Mobile (5G) | Hong Kong |
| Roaming via Singapore | China Unicom, China Telecom (5G) | Singapore |
All three operators have wide coverage. China Mobile is the largest. Both plan types connect to mainland towers and route data outside the mainland, as many travel eSIMs do. The general trade-offs of routed plans are explained in what a travel eSIM is.
Internet access and local rules
Many international services, including Google, are not accessible on local mainland Chinese connections such as hotel Wi-Fi and Chinese SIM cards. How a particular app behaves can differ by connection, location and time, and policies can change. SuperTools does not give advice on bypassing local regulations, and visitors should follow local laws. The practical approach is to set up the Chinese apps that locals use, so you can pay, navigate and travel without depending on anything else.
Apps to set up before you go
| Purpose | Apps visitors commonly use |
|---|---|
| Payments | WeChat Pay, which lets users link Visa, Mastercard or JCB cards, and Alipay, which offers options for visitors; check each app's current terms |
| Messaging | WeChat, used by hotels, guides and shops |
| Maps | Amap (Gaode) or Baidu Maps, which are more accurate in China than international map apps |
| Taxis | DiDi, which has an English-language version |
| Trains | The official 12306 railway app or website; bookings require your passport details |
| Translation | A translation app with offline language packs |
Set these up at home. Some require SMS verification to your phone number, and linking a bank card may involve your bank sending a one-time code. Keep your home SIM able to receive texts; see our dual-SIM guide.
Cash is still accepted by law, but many small businesses expect mobile payment, so having Alipay or WeChat Pay working makes daily life much easier.
Mainland China, Hong Kong and Macau are separate
For mobile purposes, mainland China, Hong Kong and Macau are three separate destinations with their own networks. A China plan usually covers mainland China only.
| Trip | What to look for |
|---|---|
| Mainland only | A China plan |
| Shenzhen or Guangzhou plus Hong Kong | A plan listing both, or two plans |
| Hong Kong, Macau and the mainland | A regional plan listing all three |
Near the Hong Kong–Shenzhen border, phones may connect to the network on the other side. Our Hong Kong guide and the multi-country guide cover this.
Coverage
| Area | What to expect |
|---|---|
| Beijing, Shanghai, Guangzhou, Shenzhen, Chengdu | Strong 4G and 5G, including metros |
| High-speed rail | Generally good, with brief drops in long tunnels |
| Popular scenic areas (Zhangjiajie, Guilin, Huangshan) | Good in towns and at main viewpoints |
| Remote western regions | More variable between towns |
Local SIM cards
Chinese SIM cards are sold under real-name registration, so visitors need their passport, and purchase is usually done in operator shops. A travel eSIM avoids the paperwork and works as soon as you land.
How much data you'll need
| Trip | Suggested data |
|---|---|
| 5 days in Beijing or Shanghai | 3 to 5 GB |
| 10 days with high-speed rail between cities | 8 to 10 GB |
| Business trip with video calls | A daily plan or 10 GB or more |
The data guide has per-activity figures.
Setting up and troubleshooting
Install the eSIM at home over Wi-Fi and switch it on after landing. Set it as your cellular data line and enable data roaming for it. If there's no service, toggle airplane mode, then select a network your plan supports manually. The troubleshooting guide covers the rest.
Emergency calls
In mainland China, call 110 for police, 120 for ambulance and 119 for the fire service.
