Will your apps work in China?

Too late. Inside the wall, VPN providers' websites are themselves blocked (ExpressVPN's site: 90% interference in measurements) and Google Play doesn't load at all. If you want a VPN as backup, install two before boarding — one always dies at the worst moment. Or skip the whole problem: on roaming data you don't need one.

Hotel brand is irrelevant. Every mainland ISP sits behind the same national filtering — the UK government's travel advice states it plainly: “Some services are permanently blocked, including: Google, Facebook, YouTube, X.” The moment your phone hops from your eSIM onto any Wi-Fi, you're inside the wall.

No — blocked isn't banned-for-you. Tourists aren't penalized for their apps failing to connect. The genuinely murky area is VPN use: the UK notes VPNs “need to be licensed by the Chinese government,” and the US advisory goes further — “Use of a VPN in China is illegal in most cases.” That's the quiet superpower of the roaming route: it involves no VPN at all. (Not legal advice; follow local law.)

Mostly the opposite. iMessage, one-on-one FaceTime, iCloud, Apple Maps and your home-country App Store all work on any network, no VPN — Apple runs officially licensed services in the mainland. The one trap: iMessage/FaceTime activation can fail on unfamiliar networks, so make sure both are activated before you fly.

Androids have it worse inside the wall. Google Play is blocked, so installs and updates can fail on local networks. Install everything before you fly, and do not rely on last-minute app downloads over hotel Wi-Fi. (Apple's App Store remains available.)

The app connects fine — but when it texts a login code to your home number, can you receive it? That needs your home SIM alive in China (international roaming enabled for SMS, even with data off). Sort this before departure: a travel eSIM carries data only — no phone number, no bank codes. Getting locked out of your own bank mid-trip is a classic.
