How to Get Online in China: Mobile Data, Wi-Fi & the Apps That Work

Published 8/18/2026 · Last updated 8/18/2026

China is one of the most connected countries on earth — and one of the most confusing to get online in. There are actually two separate problems, and most guides blur them together: getting a data connection at all, and the fact that many apps you use every day — Google, WhatsApp, Instagram — don’t work on Chinese networks. This page separates the two and tells you exactly what to set up before you board.

The 30-second answer

• The cheapest data is a local Chinese SIM — but on it, Google, WhatsApp and Instagram stop working.
• To keep your usual apps working, use international roaming on your home number, or a travel eSIM that routes through a foreign network.
• Install WeChat and Alipay before you fly — they’re your lifelines in China (see the payment guide).
• Do everything at home on Wi-Fi first — download apps and save maps before you go, because blocked apps can’t be fetched once you’re inside China.

Two problems, not one

When a visitor says “I can’t get online in China,” they usually mean one of two different things:

1. No connection — they don’t have mobile data or Wi-Fi.
2. Connected, but blocked — they have data, but Google, WhatsApp or Instagram won’t load.

These have different fixes. Getting a connection is easy and cheap. Keeping access to your usual apps is the part that needs a little planning.

Your data options

Option 1: International roaming (your home SIM)

Keep using your home number and let it roam on a Chinese carrier.

• Pro: your traffic exits through your home country, so Google, Gmail, WhatsApp and other blocked services usually keep working exactly as they do at home.
• Con: the daily fee adds up fast, and speeds can be throttled.
• Best for: short trips where convenience matters more than cost.

Option 2: A local Chinese SIM

Buy a SIM from China Mobile, China Unicom, or China Telecom at the airport or a carrier store. You register it with your passport — real-name registration is mandatory.

• Pro: the cheapest data by far, and you get a local number (useful for apps, restaurant queues, and Wi-Fi logins).
• Con: on a Chinese network you’re treated like a local, so Google, WhatsApp and other blocked services stop working.
• Best for: longer stays, or as a cheap second line alongside roaming.

Option 3: A travel eSIM

A data-only eSIM you buy before leaving and activate on arrival.

• The one thing to check: which network it actually uses. An eSIM that rides a Chinese carrier behaves like a local SIM (blocked services); one that routes through a foreign network keeps your usual apps working. Read the fine print before you pay.
• Pro: no physical SIM swap, and you can set it up at home.
• Con: data-only — no local phone number.

Wi-Fi in China

Hotels, cafes, airports and shopping malls all have Wi-Fi, but there’s a catch: many public networks ask for a Chinese phone number for SMS verification before you can log in. That’s one more reason a local number helps.

• Hotels are usually the easiest — many give you a simple password. International chains often route guest Wi-Fi internationally, so Google and WhatsApp may work there, but budget and local hotels usually behave like a local connection. Test before you rely on it.
• Cafes and malls often require a Chinese number; without one you may be stuck.

Rule of thumb: don’t assume public Wi-Fi will reach Google. Treat local Wi-Fi like a local SIM — expect blocked services, and be pleasantly surprised if a hotel network routes internationally.

What’s blocked (and what isn’t)

On a standard Chinese network (a local SIM or ordinary Wi-Fi), these commonly don’t work:

These generally do work: Apple services (iMessage, FaceTime, Apple Maps), Microsoft (Outlook, Bing), Zoom, Amazon — and, most importantly, WeChat and Alipay.

This list shifts over time, so treat it as a guide rather than gospel.

Apps to set up before you fly

Because blocked apps can’t be downloaded from inside China, do this at home on Wi-Fi:

• WeChat — messaging, payments, and everyday life. Essential.
• Alipay — payments and transport. See the payment guide.
• Apple Maps or an offline map — Google Maps is unreliable in China; Apple Maps works, and an offline map is a good backup.
• A translation app that works offline — Google Translate is blocked on local networks; Apple Translate works, and an offline dictionary is a useful fallback.
• Your airline and hotel apps — plus a copy of your bookings saved offline.

Keeping your usual apps working

The simplest way to keep Google, WhatsApp and friends working is to not run that traffic over a Chinese network: international roaming and foreign-routed eSIMs both work because your data never touches the local restrictions.

Some travelers also install a VPN before they arrive. If you go that route, set it up at home — VPN websites and app stores are frequently unreachable from inside China. This site doesn’t recommend or link to any specific service.

Pre-trip checklist

• Install WeChat and Alipay, and complete registration
• Download Apple Maps (or an offline map) for China
• Install a translation app that works offline
• Decide your data plan — roaming vs local SIM vs eSIM — and confirm which network your eSIM uses
• Save bookings and important documents offline
• Set up anything you need for blocked apps before you fly
