Internet in China: eSIM, VPN and the apps that actually work
Google, WhatsApp and Instagram will not load on Chinese WiFi. Here is how to stay connected without headaches.
The Great Firewall, explained in one minute
China filters access to much of the Western internet: Google (including Gmail and Maps), WhatsApp, Instagram, X, YouTube, Facebook and many news sites will not load. The block applies to any connection that goes out through Chinese networks: hotel WiFi, café WiFi and local SIM cards. If your plan was "I will sort it out when I land", this article will save you the first-day shock.
The travel eSIM trick
Here is the fact that changes everything: an international travel eSIM works in roaming mode, and that traffic exits through your home operator, not the Chinese network. Translation: with a travel eSIM, WhatsApp, Google Maps and Instagram work normally, with no VPN and no weird setup. For a stay of one to three weeks it is by far the simplest option. Install and activate it before boarding (you need WiFi for the QR) and compare plans for your destination in the Flamaz eSIM section.
VPN: when you really need one
You need a VPN if you will depend on WiFi (hotels, offices, longer stays) or on a Chinese SIM. Two golden rules. One: install and test it BEFORE entering the country — inside, VPN websites are blocked too. Two: the firewall evolves constantly, so pick a provider with obfuscated protocols designed for China and, if your trip depends on being online, carry a second one as backup. Be realistic: even the best have rough days there. In the Flamaz VPN section we explain which one fits your destination.
Maps and translation that will not strand you
Google Maps only half-works even with a VPN: its China data is outdated and navigation suffers. Real alternatives: Apple Maps works surprisingly well inside China, and Amap (高德地图) is what locals use, although it is in Chinese. Download offline maps before you leave. For the language: WeChat's built-in translator gets you through conversations, and Google Translate with the Chinese pack downloaded works offline even when the app cannot connect.
WeChat is your Swiss army knife
Inside China, WeChat is everything: the channel any local contact will use to message you, the everyday payment method and the door to thousands of mini programs (trains, food delivery, tickets). Create the account before the trip: registration may require an existing veteran WeChat user to verify you, and that is much easier to solve from home. How to set up payments with your card is covered step by step in our Alipay and WeChat Pay guide.
Checklist before boarding
Final five-minute review: travel eSIM installed and tested; VPN installed if you will use WiFi (plus a backup one); offline maps downloaded; Alipay and WeChat Pay set up with your card; a copy of your passport on your phone. With that, you land in Shanghai or Beijing with your phone working like at home. And for any last-minute question, the Flamaz AI chat is available in Spanish, Chinese and English.
