Does 
WhatsApp work in China?
No
on Chinese SIM cards and hotel Wi-Fi. Messages and calls don’t go through.
Yes
on a roaming eSIM or your home SIM’s roaming. That traffic leaves China first.
Not tested yet.
WhatsApp is blocked on Chinese mobile networks and Wi-Fi. It does work on a roaming eSIM or your home SIM’s roaming, because that traffic leaves China before it reaches the internet.
What to do: get a roaming eSIM before you fly, and install WeChat as a backup.

Is WhatsApp banned or just blocked?
Blocked is the better word. Mainland networks have filtered WhatsApp since about September 2017: photos and voice notes failed first, then text. There’s nothing to break on your phone or your account. The app still opens, shows your old chats and lets you type. Your messages just never leave.
That looks a lot like bad signal, so most visitors lose an hour restarting the phone before they realise what’s going on. If you see a clock icon beside every message and “Connecting…” at the top of the screen, the network is the reason.
Don’t delete it while you’re there
The usual fix for a broken app is to reinstall it. In China that makes things worse. A fresh install has to verify your number and then find your backup on iCloud or Google Drive, and Google Drive is blocked too. Leave the app installed and it will catch up by itself the moment you reach a connection that works.
Messages sent to you while you were offline wait on WhatsApp’s servers. They normally arrive once you reconnect, in China on a roaming connection or at home after the trip.
How to use WhatsApp in China
You need a connection that leaves China before it reaches the internet. There are two ordinary ways to get one:
- A roaming eSIM. You buy a data plan online, install it at home, and switch it on when you land. Your WhatsApp number stays the same, because the account belongs to your number and not to whichever SIM carries the data.
- Your home SIM on roaming. Nothing to set up, but check the price with your carrier first. Some plans include China and many charge heavily by the megabyte.
Either way, the trap is Wi-Fi. Your phone prefers Wi-Fi and hotel Wi-Fi connects inside China, so WhatsApp stops the moment the phone joins it. Turn Wi-Fi off when you need WhatsApp, or at least when a call is coming.
Calls, groups and photos
On a working connection, everything in WhatsApp should behave as it does at home, because it’s the same service reached by a longer route. Calls may lag a little, since your voice travels out of China and back. If people at home keep talking over you, drop video and stay on audio.
Watch your data on a capped plan. Text costs almost nothing, photos add up, and video calls can use hundreds of megabytes an hour. Auto-download for photos and videos is worth turning off in Settings before you go.
You’ll want WeChat anyway
Almost nobody you meet in China uses WhatsApp. Hotels, guides, drivers and shop owners will all ask for your WeChat, so set it up even if your eSIM works perfectly. WeChat is also a useful backup for reaching home if your roaming data fails: ask your family to add you before you leave.

Asked often
Update history. No test published yet.
Is WhatsApp banned in China?
It’s blocked on Chinese networks. A roaming connection is ordinary international roaming: your data simply leaves China through your home or eSIM carrier.
Can I use WhatsApp in China with an eSIM?
Yes, on a roaming eSIM. Hotel Wi-Fi still blocks it, so turn Wi-Fi off when you need WhatsApp.
Does WhatsApp work in Hong Kong?
Yes. Hong Kong and Macau aren’t affected; WhatsApp works there on any network.
Will WhatsApp calls work on hotel Wi-Fi?
No. Hotel Wi-Fi connects inside China, so calls don’t get through. Switch to your eSIM’s mobile data.
Why is WhatsApp blocked in China?
China filters many foreign messaging and social apps, and WhatsApp joined them in 2017. The government hasn’t published a detailed reason for it. WeChat is the app people use there instead.
Will my WhatsApp messages arrive after I leave China?
Normally, yes. Messages wait on WhatsApp’s servers while you’re offline and arrive once you connect, though messages left waiting for a very long time can expire.
Do I need my home SIM for WhatsApp in China?
Not for sending messages, but keep it switched on if your phone holds two SIMs. WhatsApp sometimes asks for a code by SMS, and that code goes to your home number.
