Does 
Gmail work in China?
No
on Chinese SIM cards and hotel Wi-Fi. New mail won’t arrive and sign-in fails.
Yes
on a roaming eSIM or your home SIM’s roaming. That traffic leaves China first.
Not tested yet.
Gmail is blocked on Chinese mobile networks and Wi-Fi, in the Gmail app and in most other mail apps that fetch it. It does work on a roaming eSIM or your home SIM’s roaming, because that traffic leaves China first.
What to do: get a roaming eSIM before you fly, and forward Gmail to a second address as a backup.

Will Gmail work in China?
Not on a local connection. Gmail went through months of disruption during 2014 and was cut off almost completely from late that December. Expect the same on a Chinese SIM and hotel Wi-Fi today: the app opens, your old messages are there if they were already on the phone, and nothing new arrives.
Your email isn’t lost. It keeps collecting in your account and appears once you reach a connection that works. People writing to you won’t get a bounce, so they’ll simply assume you’re ignoring them. If something urgent could land in your inbox, tell them before you leave.
Other mail apps don’t get around it
It’s tempting to think Apple Mail or Outlook will fetch your Gmail without trouble, since those apps aren’t blocked. On a local connection, most can’t. Your phone still has to talk to Google’s mail servers, and those are what’s filtered. Some apps fetch mail through their own servers abroad, and how well that works is one of the things our test records.
The address you send to matters as well. A message from a Gmail account can still go to anyone, but you can’t send it on a blocked connection, and “Sign in with Google” sites won’t open to reset a password either.
How to read Gmail in China
On a roaming eSIM or your home SIM’s roaming, your data leaves China before it reaches Google, so Gmail should open as usual. Turn Wi-Fi off first. Your phone will join hotel Wi-Fi whenever it can, and Gmail goes quiet again as soon as it does.
If you can, also set up forwarding before you fly, so you have a second way in. In Gmail on a computer, go to Settings › Forwarding and POP/IMAP and add an address you can read on any network, such as Outlook or iCloud Mail. It needs a confirmation from the other inbox, so you can’t do it once you’re there on Wi-Fi.
Sign-in codes are the real risk
Google notices when an account appears in a new place. Signing in from a new country or a new device can trigger a check that sends a code to your home number or asks you to tap a prompt on another phone. If your home SIM is switched off, or the prompt can’t reach your phone, you can lock yourself out.
- Stay signed in on your phone. Avoid signing out to “fix” a blocked app.
- Save your Google backup codes where you can read them offline.
- Keep your home SIM switched on so SMS codes can arrive, even when the eSIM carries your data.
Work email is a different question
If your company runs its email on Google Workspace, the same block applies. Corporate networks in China sometimes have their own arrangements, but a tourist on hotel Wi-Fi doesn’t. Ask your IT team before you travel. Email on Microsoft 365 is usually reachable on Chinese networks: see the full table of apps.

Asked often
Update history. No test published yet.
Can I use Gmail in China?
Yes, on a roaming connection. Gmail is blocked on Chinese SIM cards and hotel Wi-Fi, but it should open on a roaming eSIM or your home SIM’s roaming, with Wi-Fi off.
Is Gmail blocked in China?
Yes. It has been almost completely cut off on mainland networks since the end of 2014, along with most other Google services.
Does Gmail work in Apple Mail in China?
Not reliably on a local connection, because Apple Mail still has to reach Google’s mail servers. On a roaming connection it should work as it does at home.
Will I lose emails while I’m in China?
No. Email keeps arriving in your account. You just can’t see it until you reach a connection that isn’t filtered, so nothing is lost and nobody receives an error.
Does Gmail work in Hong Kong?
Yes. Hong Kong and Macau aren’t affected, so Gmail works on any network there.
Why can’t I sign in to Gmail in China?
If you’re on Chinese Wi-Fi, the sign-in page is blocked. If you’re on a roaming connection, Google may be asking for a code because you appear to be in a new place. That’s why it helps to keep your home SIM on and carry backup codes.
What’s the best email to use in China?
Outlook and iCloud Mail are the usual choices for visitors, because both are reachable on Chinese networks. Forward your Gmail to one of them before you travel.
