A First-Timer's Connectivity Checklist for Beijing and Shanghai

First trips to China cluster around the same two cities, and the same small set of phone tasks separates travelers who land ready from travelers who spend their first evening troubleshooting. This is the checklist we send friends before their first Beijing or Shanghai trip — short enough to actually do, ordered so each step still has the easy internet it needs.

The one-week-out list

Everything in this section happens at home, on your own Wi-Fi, while the app store is a tap away. That timing is the entire trick, and it is why we wrote a whole article on installing before you fly.

Task	Done
Confirm eSIM support: dial *#06# and look for an EID; check the phone is unlocked	☐
Update the operating system and every app you use daily	☐
Download offline maps for Beijing and Shanghai, plus the Chinese translation pack	☐
Install our app, buy a mainland plan, install the eSIM over Wi-Fi	☐
Set up the tourist flow of a mainland payment app with your bank card, from home	☐
Save your hotel names and addresses in Chinese characters, offline	☐
Point mobile data at the eSIM; data roaming on for the eSIM line only	☐

Three of these deserve a sentence. The EID check matters because phones originally sold in mainland China often ship without eSIM — better to learn that at home. The payment-app step matters because the big mainland payment apps offer visitor flows that link a foreign bank card, and their verification steps are far easier over your home connection; how smoothly a given card links is between the app and your bank, so test it with a small setup at home rather than at a ticket counter. And the hotel-address step matters because your taxi driver reads characters, not your transliteration.

The eSIM install, if the concept is new to you, is genuinely a two-minute job — what an eSIM is explains the idea, and our device guides walk each phone through it. Installing early costs nothing: validity starts when the eSIM first connects in mainland China, not when you buy.

Landing day: the first thirty minutes

Doors open, airplane mode off. The eSIM finds a network — in Beijing Capital, Daxing or Shanghai Pudong this takes moments, and the apps you use at home carry on working over it, because a roaming eSIM’s data routes through an international network, the way roaming always has. Send the family message, load the map, order the ride. Resist the airport Wi-Fi: its login portals often want a local number for a verification text, and you have a better connection in the phone already.

Three quick checks in the arrivals hall. Signal bars on the eSIM line: present. Your home SIM: still registered for calls and texts, so bank codes reach you. Data roaming on the home SIM: off, so it cannot quietly bill you in the background. That is the whole landing routine.

The first evening: hotel habits

At check-in your phone will join the hotel Wi-Fi, and this is where first-timers hit the trip’s one genuine surprise: hotel Wi-Fi is a local connection under local network rules, and an app that ran fine on the eSIM all day may behave differently on it. The fix is a habit, not a setting — when an app misbehaves on Wi-Fi, toggle Wi-Fi off and let the eSIM carry it. Keep Wi-Fi for the heavy things it is good at, streaming and photo backups, and keep the eSIM for everything you rely on. The full division of labour is in hotel Wi-Fi vs your eSIM.

City-specific notes

Beijing spreads out, and its sights are far apart: budget map-and-navigation data for long taxi rides, and expect brief signal dips inside the older subway stretches — coverage in stations is generally excellent. A day trip to the Great Wall stays comfortably on the network at the restored sections tourists visit.

Shanghai is denser and more walkable, with superb coverage throughout; the connectivity note here is simply that you will use the payment app constantly — street food, metro, museums — so that pre-flight setup pays for itself in the first hour. In both cities, tethering a laptop to the eSIM is included at no extra cost, which turns any café into an office.

If your itinerary continues to Hong Kong or Macau, remember those are separate networks sold as separate destinations — the details live in what your eSIM covers.

The point of all this

None of these steps is hard, and every one is dramatically easier at home than abroad. Do the seven-row table in the week before departure and your first China evening is spent on dumplings rather than settings — which is, after all, what the phone is for.
