Where to stay
Does the wifi in a Shanghai hotel work?
Usually yes: the wifi connects, it is often quick, and the connection itself is a real one. What tends not to work is what a foreign visitor expects to reach through it, since a set of foreign sites and apps is unreachable on an ordinary hotel network and the list shifts over time. Anyone who depends on a particular service should sort out the route before flying.

The wifi works; where it reaches is another matter
The wifi in a hotel room usually does what it says: there is a password, it connects, and it is usually not slow. The answer has two parts: the connection is normally fine, and the problem is where it can go once it leaves the building. A hotel network is not a special line but an ordinary one on the mainland public internet, and the filtering applies just the same.
What works, and what does not
What works is substantial: domestic sites and apps run on local routes, load quickly and stream video without stalling, and maps, ride-hailing, payments and bookings need no extra setting.
What does not work is a category of things: foreign social and messaging apps, some international news sites, Western streaming services, foreign search and mapping services, and a number of workplace and cloud storage tools whose servers sit outside the mainland. The list is not fixed and changes over time. So plan on the basis that a category may be unreachable, and do not put anything that matters behind a single app.
Changing the route, and the parts of a hotel that vary
Most people do not fight the filtering; they change the route. An international roaming plan or a travel eSIM may leave the phone technically abroad, with traffic routed through your home carrier or a Hong Kong or international one, behaving as it does at home. Not every eSIM does this: one running on a mainland operator is still a local line, and sales pages barely distinguish them, so confirm the routing of the specific plan with the provider before you travel, and ask whether it is data-only or comes with a number.
Reception may mention a second, international network: a few hotels do keep a separate line for foreign guests, others simply have a differently named one. Ask, but treat it as luck rather than a plan. A wired port on a business hotel desk is commoner and steadier. Speed and reliability depend on where you are: the lobby is often excellent and the room poor, and rooms by the lift or in a corner are the usual weak spots. A business hotel is generally steadier than a budget one, but that is not a guarantee. When the room fails, switch to a phone hotspot.
Calls, VPNs, and what to settle before you leave
If a video call cannot be missed, test early: try it in the room on arrival day, with the software you will use. If the room fails, move to the lobby; if the lobby fails, use the hotspot; if all of it fails, ask about a meeting room to borrow, and keep a fallback that does not need video.
A VPN is a legal grey area here; only government-approved services are lawful, enforcement against visitors on personal phones is rare, but that is neither a guarantee nor something to lean on. The sensible course is to plan a trip that works without defeating anything, and this article gives no instructions.
What to settle before you leave is a short list: how you will get online, whether you need a Chinese phone number, offline maps and translation downloaded, an agreed way to reach people at home, and your hotel name and address screenshotted and stored locally. The one thing not to leave until arrival is the connection itself: provider sites are blocked inside the mainland, so on landing you can neither compare calmly nor be sure the plan you buy is routed the way you need.
