The internet works differently in China, and this catches more first-time visitors off guard than anything except payments. Google, WhatsApp, Instagram, YouTube, Gmail, Facebook and X are blocked on Chinese networks. But there is a well-tested way around it — and the key decision happens before you board your flight, not after you land.
The short answer
Buy a travel eSIM (from providers like Airalo, Holafly or Nomad) and install it before you leave home. A travel eSIM routes your mobile data through a network outside China — usually Hong Kong or Singapore — so Google, WhatsApp and Instagram work on your phone with no VPN needed. Separately, install a reputable VPN before you fly as a backup for hotel Wi-Fi and laptop use. Do not count on downloading either after you arrive.
The Great Firewall: what is actually blocked
On any Chinese network — local SIM, hotel Wi-Fi, café Wi-Fi, airport Wi-Fi — the following are unavailable: Google (search, Maps, Gmail, Drive), WhatsApp, Instagram, Facebook, YouTube, X, and most Western news sites. The blocking list shifts over time, so check the current situation before booking, but assume the full set is blocked and plan accordingly.
What works fine without any workaround: Apple’s services, WeChat, Alipay, and Chinese apps like Amap (高德地图) and DiDi.
Why a travel eSIM bypasses the firewall
This is the part worth understanding, because it decides everything else. A travel eSIM is registered to an overseas carrier — usually based in Hong Kong or Singapore. Your phone connects to a Chinese cell tower like normal, but instead of exiting through a mainland internet gateway (where the firewall inspects traffic), your session is tunnelled back to the carrier’s overseas network and enters the internet from Hong Kong or Singapore.
The firewall only filters traffic that exits through Chinese gateways. Your eSIM traffic never takes that exit, so there is nothing to filter. Google and WhatsApp simply see a normal connection. This is not a VPN you have to switch on — it is how the connection is built, working from the moment you turn on mobile data.
One important caveat: this applies only to your eSIM’s cellular data. The instant you join hotel or café Wi-Fi, you are back on a Chinese network and blocked apps stop loading.
Your options, compared
Travel eSIM — the default choice for most visitors
Cost: roughly US$4–14 for a week of data, depending on provider and allowance. Setup: buy online before departure, scan a QR code at home, land already connected. No queues, no passport paperwork, no VPN install. This is the simplest and most reliable option, and the one we recommend to nearly everyone.
Choosing one: pick a provider that explicitly mentions international routing — “Hong Kong routing”, “international gateway”, or “traffic exits via Hong Kong”. All major travel eSIMs currently sold for China use this kind of roaming connection, but budget options that route directly through Chinese carriers behave like a local SIM (i.e. blocked), so the explicit mention matters.
Phone compatibility: you need an eSIM-capable phone (most iPhones from XS onward, recent Samsung and Pixel models). Check your settings before buying.
Local Chinese SIM — for long stays and a real +86 number
The three state carriers — China Mobile, China Unicom, China Telecom — sell tourist SIM packages at airport counters for roughly ¥100–300 (US$14–42). The upsides: a genuine Chinese phone number, which makes WeChat, Alipay and DiDi registration smoother, and often the best raw coverage.
The downsides: every local SIM sits behind the Great Firewall — Google and WhatsApp are blocked unless you run a VPN — and buying one requires real-name registration with your passport (sometimes with facial recognition) at a store or airport counter. Worth it for stays of several weeks; overkill for a week-long trip. Some travellers carry both: a local SIM for the +86 number, an eSIM for the open internet.
Home carrier roaming — usually the worst value
International roaming from your home carrier connects through Chinese towers and your traffic passes through the Great Firewall — so blocked apps stay blocked, just like a local SIM. Roaming is also expensive (many carriers charge £6–10 / €7–12 / US$8–12 per day), and budget carriers may not cover China at all. Technically it can work, but a travel eSIM beats it on price and reliability in almost every case.
VPN: the backup you install at home
Even with an eSIM, a VPN is worth having: for your laptop, for long evenings on hotel Wi-Fi, and as insurance if your eSIM misbehaves. The rules are simple:
- Install and test it before you fly. VPN provider websites are blocked in China, local app stores strip out VPN apps, and Google Play does not operate there. You cannot reliably set one up after arrival.
- Expect variable reliability. VPN reliability in China has been uneven, with periodic crackdowns making some providers unstable. Choose one with strong traffic obfuscation and a track record in China, and treat it as a backup, not your primary plan.
- Know the legal position. Unauthorised VPNs are technically restricted in China, though personal use by travellers is widely tolerated. This guide is practical information, not legal advice.
Hotel and public Wi-Fi: the reality
Hotel Wi-Fi in China is generally fast and free, and fine for anything that is not blocked — video calls on WeChat, browsing Chinese sites, hotel apps. But it is a domestic connection: without a VPN, Google, WhatsApp and Instagram will not load. The practical habit: leave mobile data on for blocked apps, switch to Wi-Fi for heavy downloads and video, and run your pre-installed VPN on Wi-Fi when you need the full internet on a laptop.
Airport and high-speed-rail-station Wi-Fi usually require a verification step (often an SMS code, which needs a working phone number) and are similarly filtered.
Apps to have ready before departure
- Your eSIM provider’s app and the eSIM profile itself, installed and tested at home.
- A VPN app, installed and tested at home.
- Translation: download offline language packs (Chinese ↔ your language) in your translation app of choice — camera translation of menus and signs is a daily lifesaver, and offline packs work without any connection.
- Maps: Google Maps works on your eSIM’s cellular data in major cities, but download offline areas anyway. For metro and walking directions on Wi-Fi, Apple Maps works in China, and locals swear by Amap (高德地图) — it is Chinese-only, but its transit routing is the best available.
- Alipay and WeChat: set these up at home too, following our payment guide — you will need them from day one.
- WeChat specifically is also your messaging fallback: it works on every network in China, blocked or not, and your concierge, hotel and driver will all reach you through it.
