Instagram doesn't work in China on a Chinese SIM card or on hotel Wi-Fi, and neither do WhatsApp, Google search, Gmail, Google Maps, YouTube, Facebook, X or Telegram.
This applies everywhere in mainland China, including Hainan and its resort city Sanya; the island's visa-free entry for tourists changes nothing about its internet. The apps open, then sit on a loading screen, because the connection to their servers is filtered at the national gateways.
Two things do keep those apps working for travelers. International roaming and most travel eSIMs, because the data exits to the internet in your home country rather than in China; and a VPN that was installed and tested before departure, because the filter also blocks the websites and app stores you would need to set one up. Below: what works without doing anything, what doesn't, and how each option behaves in practice.

What apps are blocked in China
Everything from Google, including search, Maps, Gmail, Drive and the Play Store. Meta's apps: Facebook, Instagram, WhatsApp, Messenger and Threads. YouTube, X, Telegram, Signal, Discord, Reddit and Wikipedia. Many Western news sites. Some cloud storage and note-taking services. ChatGPT and similar tools. The list moves over time, but the core has been stable for years.
Which apps you can install is a separate question: the Chinese App Store and Chinese Android stores don't carry many of them, so install what you need at home.

WeChat and Alipay, which handle payments, messaging, taxis and most daily life. Apple Maps, iMessage and FaceTime. Baidu Maps and Amap. Trip.com for hotels, trains and flights, DiDi for taxis. Bing usually loads. Most banking apps from home work, as do plain phone calls and SMS. Microsoft services are largely fine. Your hotel's booking confirmations, airline apps and translation apps with offline packs downloaded in advance all work.

Why Instagram works on roaming in China
When you roam on a foreign SIM, your phone uses the Chinese tower only for the radio signal. The data is handed to your home carrier under the roaming agreement and exits to the public internet in your home country. The Chinese gateways treat it as carrier-to-carrier transit, not as a user connection, and don't filter it. So on roaming, Instagram, WhatsApp and Google work exactly as at home, no VPN involved.
Most travel eSIMs work the same way: they're profiles of a foreign carrier, often from Hong Kong or Singapore, visiting China as a guest. The trade-offs are price and latency, since every request takes a detour through the home network. The full comparison, including what a local SIM gives you instead, is in eSIM, roaming or a local SIM in China.
How to use Instagram in China on a local SIM
With a China Mobile or China Unicom SIM, or on hotel Wi-Fi, your traffic leaves the country inside China and the filter applies to it. If you want your usual apps on that connection you need a VPN, and the whole point is preparation:
- Install the app and sign in before you fly. VPN websites and the app-store pages you'd need are usually unreachable from Chinese networks.
- Set up two options, not one. Classic protocols like OpenVPN and WireGuard get recognized by the filter and often just won't connect. Protocols built to look like ordinary HTTPS, like VLESS with Reality, hold up better. Neither is guaranteed.
- Test at home: connect, open What Is My IP, confirm the address and country changed, run the WebRTC leak test.
- Keep roaming in your back pocket for the days when nothing connects at all.
The legal side, the protocol details and the on-arrival troubleshooting are in VPN for China: what travelers need to know.

Does Instagram work in Sanya and Hainan?
Hainan is a free-trade port with visa-free entry for tourists from many countries, and it's piloting a program called Global Connect that gives some users unfiltered internet. According to the South China Morning Post, it's open to employees of companies registered in Hainan who hold a 5G plan with China Mobile, China Unicom or China Telecom, with approval taking up to five months. It isn't available to tourists, and hotel Wi-Fi in Sanya is ordinary Chinese internet. Some international resorts advertise access to foreign services for guests; treat that as something to verify on the spot, not to count on.

Before you fly: a short checklist
- Decide how you'll be online: roaming, travel eSIM, or local SIM plus VPN.
- Install WeChat and Alipay and link a card. QR payments are the default there and cash gets rarer every year.
- Download offline maps and an offline translation pack while you still can.
- If you're taking a local SIM, install and test the VPN at home with two protocols configured.
- Save your hotel address in Chinese characters and your embassy's number in your notes, not only in a chat app.
If something won't load and you can't tell whether the problem is the network, the connection type or the tunnel, describe it.
Help me work out what is wrong with my
connection while traveling.
Where I am: (city, province in China).
Connection: (roaming / travel eSIM / local SIM /
hotel Wi-Fi).
What will not load: (list it).
What loads fine: (list it).
Tunnel: (on and connected / on but will not
connect / not using one).
Tell me which part is failing: the network
itself, the way I am connected, or the tunnel.
And what to check first.
If the data is not enough, ask instead of
guessing.Posting to Instagram from China
On roaming or a travel eSIM, uploads to Instagram and WhatsApp work as they do at home, only with more latency. On a local SIM with a VPN, uploads go through the tunnel and are noticeably slower on busy evenings; large videos are easier to send in the morning or over the hotel Wi-Fi with the VPN on. If a post refuses to upload, check the connection on What Is My IP before blaming the app: a dropped tunnel looks exactly like a broken app.
404 VPN provides VLESS in its Android and macOS apps, DNS resolved inside the tunnel, a kill switch on Android, and locations in Hong Kong and Tokyo. The free plan is enough to test everything before departure. We don't promise availability from every Chinese network; we do recommend setting up at home. Start on the home page.
