eSIM for China

China operates on a scale that is hard to grasp until you are standing in it: Shanghai's skyline across the Huangpu, Beijing's hutongs an alleyway's width from six-lane traffic, the Great Wall running off over the hills, Chengdu teahouses where an afternoon disappears. It is also the most app-mediated country you will ever visit. Menus, taxis, tickets, museums and payments all live behind a QR code, so being online is not a convenience here, it is how the country works.

How to install your China eSIM in 3 steps

Install before you fly. That advice applies everywhere, and in China it matters more than anywhere else: the app stores and websites you would normally use to set up a mobile plan are difficult or impossible to reach from inside the mainland, so arriving with nothing installed is a genuinely awkward position to be in.

1. Buy your plan. Pick an allowance based on how long you are staying and how much you will lean on maps and translation, which in China is usually more than you expect. Plans start from £0.61.
2. Scan and install on Wi-Fi. On iPhone, Settings > Cellular > Add eSIM and scan the QR code. On Android, Settings > Network & Internet > SIM Manager > Add eSIM. Do this at home or on airport Wi-Fi before departure, never after landing.
3. Activate on arrival. Landing at Beijing Capital, Daxing, Shanghai Pudong, Hongqiao, Guangzhou or Shenzhen, switch on data roaming for the new eSIM line. Coverage normally appears inside the terminal, so you can order a car or check a train before you reach the exit.

Mobile network coverage in China

China runs the largest mobile network on earth, and in the places visitors actually go it is excellent. Our plans ride on China Mobile, or on China Unicom and China Telecom, depending which you choose.

Cities

5G is dense and genuinely fast across Beijing, Shanghai, Guangzhou, Shenzhen, Chengdu, Xi'an, Hangzhou and every other major city, including on most metro lines and throughout the high-speed rail network. China Mobile has the largest subscriber base and the broadest footprint; China Telecom and China Unicom are close behind in the cities and often indistinguishable in day-to-day use. Indoor coverage in malls, museums and restaurants is usually strong, which matters when the menu is a QR code.

Beyond the cities

Coverage follows people and infrastructure. Along the eastern seaboard and the rail corridors you will rarely lose signal. Head into western Sichuan, the Tibetan plateau, the Xinjiang deserts, the Inner Mongolian grasslands or the mountains around Zhangjiajie and it becomes patchier, with 4G rather than 5G on the main routes and real gaps between them. If your itinerary is genuinely remote, download offline maps before you set out and treat connectivity as a bonus rather than a given.

How much data do you need for your trip to China?

Budget more than you would for a comparable trip in Europe. Translation apps run constantly, maps are in near-permanent use, and paying for almost anything means opening an app.

Trip	Typical use	Suggested plan
Long weekend in one city	Maps, translation, messaging, mobile payments	1 to 3 GB
One to two weeks, several cities	The above, plus rail bookings, photos to family, some video	5 to 10 GB
Longer trip or working remotely	Video calls, cloud sync, tethering a laptop	20 GB or more

Plans here span small top-ups through to large monthly bundles, so you can start modest and add more rather than overbuying. If you are unsure, err upward: running out mid-trip in a country where your usual app store is hard to reach is a worse problem than a little unused data.

eSIM vs. roaming vs. a local SIM in China

This is the decision that matters most in China, and it is not really about price.

A local Chinese SIM puts you on the domestic internet. It requires real-name registration against your passport, and it means the services most visitors depend on are unavailable: Google Search, Gmail, Google Maps, WhatsApp, Instagram, Facebook, YouTube and X are all blocked from inside the mainland. You would be navigating with Amap or Baidu Maps and messaging on WeChat, which is exactly what residents do, and which is a steep learning curve for a two-week trip.

A travel eSIM connects to the same Chinese towers but carries your traffic back out through the operator's own international gateway, the way any roaming visitor's phone does. In practice that means your usual apps keep working as they do at home, with no separate arrangement needed. This is the single biggest reason travellers choose an eSIM for China rather than picking up a SIM on arrival.

Roaming on your normal contract works, but China sits outside the inclusive allowances on most home plans, so daily charges or per-megabyte rates apply and a fortnight adds up quickly. Check what your own tariff says about China specifically before you rely on it.

One boundary worth knowing: Hong Kong and Macao are separate telecoms markets. A mainland China plan does not automatically cover either, and a Hong Kong plan does not automatically cover the mainland. If your trip crosses those borders, check the coverage list before you travel.

Tips for staying connected in China

• Set everything up before you go. Install the eSIM, download offline maps, and add the apps you will need while you can still reach the stores easily.
• Keep your home number active. Bank and email verification codes still arrive by SMS. Dual SIM lets your eSIM carry data while your usual number handles texts.
• Get WeChat and Alipay working early. Both now accept most foreign cards, and between them they cover payments, transport, tickets and translation. Cash is accepted but increasingly unusual.
• Download an offline translation pack. Signage outside the major cities is often Chinese only, and camera translation is genuinely useful.
• Book trains through an English-language app. High-speed rail is superb and sells out on popular routes, so book ahead rather than at the station.
• Power is 220V with type A, C and I sockets. UK and European visitors need an adapter.
• Emergency numbers are 110 for police, 120 for an ambulance and 119 for fire.
