Five China Travel Systems to Set Up Before You Fly

China runs on five systems a foreign visitor has to use: mobile data, mobile payment, high-speed rail, a short list of Chinese apps, and accommodation registration. Four of the five are easier to set up before you fly, because they need something you lose in the air, such as a verification text sent to your home number. This page is the map; each system has its own guide.

What are the five systems that trip up foreign visitors?

None of the five is optional, and none of them defaults to what a foreign visitor already has. A foreign credit card is not the normal way to pay, an international phone number is not the normal identity, and a passport, not a booking reference, is the document that opens a station gate. The five are data, money, rail, apps and accommodation registration.

Set up before you fly or on arrival: what each system costs you if you skip it.

System	What it covers	Before you fly?	What happens if you skip it
Mobile data	An international eSIM or a roaming plan that works when you land	Yes. Buy, install and test; switch on at landing.	No map, no ride-hailing, no QR payment, and no way to receive the code the apps send.
Money	Alipay or WeChat Pay with a linked foreign card, plus a little cash	Yes. Link the card and make one small test payment.	You reach for a card in a shop that takes only a QR code, or your bank blocks the first charge.
High-speed rail	A 12306 account with a verified passport, plus a seat class	Mostly. Create the account and finish verification.	The date you want sells out, or verification fails and you cannot buy at all.
Apps	WeChat, Alipay, Amap, 12306, Trip.com, a translation app	Yes. Install and sign in on your home network.	A sign-in needs a code sent to a number you can no longer use.
Accommodation registration	Hotel check-in, or a registration for a private stay	No. It happens on arrival.	A private stay without registration is the one administrative step that can be penalised.

Only the last one happens on arrival. The other four are decisions you make while you still have your home number, your bank’s fraud line and a working app store.

Which of these can you only set up at home?

Data, payments and the rail account need something that disappears somewhere over the air: a text message to your home number, a call to your bank, and an app store that will still download Chinese apps. Set all three up about a week before departure, then test each one while your own network is still the fallback.

1. Buy and install an international eSIM, and keep your home SIM active for the first day so verification texts still reach you. The China eSIM guide covers which plans work and which handsets support a local eSIM.
2. Link a Visa or Mastercard to Alipay and make one small payment in your home currency, which proves the card is enabled for overseas use. The payments guide has the limits and the fee rule.
3. Create a 12306 account and complete passport verification: automatic when your name matches the passport exactly, a manual photo upload when it does not. See high-speed trains.
4. Install WeChat, Alipay, Amap, Trip.com and a translation app, then sign in once. The internet and apps guide says what each one replaces.

What actually goes wrong on day one?

The failures are specific, they repeat across travellers, and most are avoidable with one phone call or one checkbox. A card is declined because the issuer was never told you would be abroad. A data-only eSIM cannot receive the verification text that a payment app wants. A railway registration fails because the name does not match the passport character for character. None of this is exotic.

• Card declined at the first till. Your bank flagged a foreign charge it did not expect. Call the number on the back of the card before you fly, give the dates and the country, and ask them to allow the charge.
• Data that connects but does nothing. The eSIM is installed but the phone is still on the wrong line. Set the data line manually, switch on roaming for that line, and wait a minute.
• A QR code that will not scan. Personal payment codes and merchant codes look alike and behave differently. Look for a printed stand code, or pay cash, which merchants are not allowed to refuse.
• No paper ticket to show. There is nothing to print, because the booking lives against your passport number. Some automatic gates cannot read a foreign passport, so queue at the staffed lane beside them.

Do you have to register where you are staying?

Only if you are not in a hotel. Hotels register every foreign guest with the local public security office as part of check-in, so there is nothing for you to do. If you stay in a private home, a rented apartment or with friends, the registration is your responsibility and the deadline is 24 hours from arrival.

Foreigners staying in a private residence must complete accommodation registration at the local public security office within 24 hours of arrival (Exit and Entry Administration Law, Article 39, as summarised in the National Immigration Administration notice of 20 March 2026).

Since 20 March 2026, seven provinces and municipalities have run an online channel for this through the NIA website and its app: Hebei, Liaoning, Zhejiang, Hubei, Guangxi, Chongqing and Sichuan. Online registration has the same legal effect as attending in person, and the scheme is being extended. Elsewhere, take your passport and your host’s ID to the nearest public security office.

Where should you start if you only have an hour?

Work in the order that unlocks the next step. Data comes first, because everything else needs a network or a text message. Payment comes second, because a linked card turns the phone into a wallet. Rail comes third, because the good seats on a short trip go first. Apps and registration can wait until the week you leave.

If you have an hour today, give it to the eSIM and the card link. An hour gets you a working phone on landing, and a working phone is what turns the other four systems from problems into tasks. Start with the eSIM guide, then the payments guide; both are much harder to finish from an arrivals hall.
