Does Slack work in China?
Partly — Slack is reachable in mainland China, but unreliable. Here's what that means in practice, how to get around it, and what people in China use instead.

Works sometimes — don't rely on it
Slack is not fully blocked, but access is inconsistent: expect slowdowns, timeouts, or censored results, and don't build your trip around it.
- Have a fallback ready — a travel eSIM or a tested VPN makes access far more predictable.
- Download or export anything you'll genuinely need (documents, tickets, maps) before you travel.
- Status can change with no notice, and can differ by city, carrier and time of day.
Worth knowing: Access itself is inconsistent, but the bigger issue for anyone based in China is that Salesforce shut down all Greater-China-billed Slack workspaces in 2026 — a business decision, not a firewall block.

Getting online in China, whatever you use
Set everything up before you fly
This is the one rule that matters. Install your VPN, download offline maps and a translation pack, and sign up for WeChat and Alipay while you can still reach the app stores and verification pages. Doing it after you land is dramatically harder.
A travel eSIM is the easiest way through — and increasingly the more reliable one
An eSIM bought before departure routes your data through a foreign carrier, so blocked apps typically work without a separate VPN, and you have data the moment you land. VPN detection inside China has gotten more aggressive in recent years, so for a short trip an eSIM is now the more dependable fix, not just the simplest one.
A local SIM puts you inside the firewall
A China Mobile or Unicom SIM gives cheap, fast data but sits behind the Great Firewall, so you'd still need a VPN for blocked apps. Buying one also requires your passport and takes time at the counter.
Public wifi is common but awkward
Free wifi is everywhere, but many hotspots verify you by SMS to a Chinese phone number, which visitors often don't have. Mobile data is usually the smoother option.
Using a VPN as a tourist
VPNs occupy a legal grey area in China, but the practical risk to an ordinary foreign tourist using one for everyday apps is negligible — it is routine among visitors and expatriates. Reliability has gotten less predictable, though: detection has improved and connections can drop with no warning, sometimes nationwide for a while. Pick a reputable, obfuscated provider, test it before you fly, and treat a travel eSIM as your real backup rather than the other way round.

How can I use Slack in China?
Use a travel eSIM bought before you fly — it routes your data through a foreign carrier, so blocked apps generally work with no VPN. The alternative is a reputable VPN, installed and tested BEFORE you arrive, since VPN sites and app-store downloads are blocked once you are in China.
