你的应用在中国能用吗？

Blocked since 2014 — the website, the app, and mail-client sync all fail on mainland networks. Normal in Hong Kong and Macau.

Blocked — the whole google.com domain family sits behind the firewall, on the UK Foreign Office's permanent block list.

Blocked — and even over a VPN its China map data is years out of date. Amap Global or Baidu Maps is what actually navigates.

Blocked — part of the google.com domain-family block. Download what you need before you fly.

Blocked — same google.com domain block as Gmail and Drive.

Blocked since 2017 — texts, voice, and video all fail on mainland networks. Server-level block: reinstalling changes nothing.

Blocked on mainland networks — on the permanent block list. A VPN or an HK-routed travel eSIM brings it back.

Blocked on mainland networks — restored by a VPN (installed before arrival) or a travel eSIM routed through Hong Kong or Singapore.

Blocked on mainland networks — bring a VPN installed before arrival to watch.

Works — foreigners link international Visa/Mastercard cards, with travel-sized spending limits.

Works — China's Uber registers with a foreign number and takes in-app payment.

Works — Apple's services pass through the firewall untouched, payments included.

Works normally, VPN or not — blue bubbles send and receive, photos and group texts included.

Works without a VPN — 1-on-1 video at least. No group calls in the mainland; audio is disabled on iPhones bought in mainland China.

Works with an international card, but at a lower tier — P2P transfers and red packets are restricted.

Works, but full features need a +86 number, and there's no English interface.

Works — passport real-name registration is accepted, and buying without a Chinese number has known workarounds.

Usable with habits — most hotspots demand a +86 registration code, and open networks are no place for passwords or banking.
