China runs a parallel internet. Most Western apps need help getting through — and the help has to be installed before you land, because the sites that sell it are blocked from inside.
What’s actually blocked
China’s internet is a complete parallel ecosystem, not a filtered version of the one you know. The practical upshot: most Western apps either fail outright or half-work in ways that are worse than failing.
The obvious casualties are Google in all its forms, WhatsApp, Facebook, Instagram and TikTok — yes, TikTok; the domestic app is Douyin and it’s a different product.
The less obvious ones cause the real trouble. Far more apps depend on Google’s infrastructure than people expect: sign-in flows, push notifications, embedded maps, font and script hosting. Google Maps won’t load. Your email may not sync. Depending on the bank, your banking app may sit there spinning. Anything you rely on daily should be assumed broken until proven otherwise.
VPN or eSIM?
VPN reliability in China is genuinely unpredictable. Services work for months and then stop for a fortnight, usually around politically sensitive dates. Marketing claims are not a good guide.
The approach that has held up best is a travel eSIM that routes your data internationally. You’re not tunnelling out of the domestic network; your traffic never enters it. There’s nothing to configure, nothing to reconnect, and no cat-and-mouse.
⚠️ This must be set up before you enter China. App stores and provider websites are largely unreachable from inside, so buying and installing an eSIM after landing ranges from awkward to impossible. Install it, activate it, and confirm it works while you’re still at home.
Worth knowing about the limitation: an eSIM only routes mobile data. The moment you join hotel or café Wi-Fi, you’re back on the domestic internet and the blocks return. If you want unrestricted access on a laptop, you’ll need to tether from the phone.
Our app guide covers what to install alongside it.
The setup that works
- Before you fly: eSIM installed, activated and tested; WeChat and Alipay registered and verified; Amap downloaded
- On arrival: local SIM card at the airport if you’re staying more than a week or two — many Chinese apps only send verification codes to a +86 number
- For navigation: Amap or Baidu Maps, not Google
- For messaging: WeChat, since that’s where everyone you meet will be
- For insurance: passport scan, bookings, tickets and addresses saved offline on the device
The four mistakes people actually make
- Installing the eSIM after arriving, when the provider’s site is unreachable
- Trusting Google Maps, whose China data is years stale
- Not downloading maps and documents for offline use
- Assuming WhatsApp or Instagram will just work — they won’t, and you’ll need another way to tell people you landed
