When you are in China for treatment, a connectivity failure has real costs: a missed appointment call, a driver who cannot find the hospital entrance, family members who stop receiving updates. The good news is that everything can be prepared before departure. The short version: for data, prefer international roaming or a travel eSIM (your usual apps generally work as they do at home, at the price of higher cost and average speed); for a cheaper option, get a Chinese local SIM (passport real-name registration required); for payments, bind an international credit/debit card to Alipay or WeChat Pay (US$5,000 per transaction, US$50,000 per year) and carry a small amount of cash; and the night before you fly, download offline maps and translation packs. Here is the full picture.
Three Ways to Get Online — Pick One First
| Option | Pros | Cons | Best for |
|---|---|---|---|
| International roaming (home SIM/eSIM roaming) | Works out of the box; your usual foreign apps are generally accessible directly | Expensive; often slow | Medical travelers, short stays |
| Travel eSIM (bought before departure) | Cheaper than carrier roaming (commonly from about US$4–20 per week), data on landing | Limited data allowances; must be installed before departure | Most short-term visitors |
| Chinese local SIM | Cheapest, generous data; gives you a Chinese phone number | Passport real-name registration; some foreign apps not directly accessible | Stays of several weeks or more |
To be clear: roaming and travel eSIM traffic is typically settled through your home/international carrier's network, so your usual foreign websites and apps generally work as they do at home; on China's local networks, some foreign websites and apps are not directly accessible. This is not a technical glitch but the current reality of the mainland network environment — plan your medical trip around it.
International Roaming and Travel eSIM: Why Medical Travelers Should Consider Them First
During a medical trip, what you need most are the familiar tools that just work: messaging family, searching with your usual engine, receiving the hospital's English emails, joining a video consultation. Roaming and travel eSIM traffic does not pass through mainland China's local networks, so these apps usually work with no extra setup — the main reason we rank them first.
Two practical notes:
Price and speed: carrier roaming tends to be expensive with frequent speed caps; third-party travel eSIMs are better value, commonly from about US$4–20 per week depending on the data pack.
Install before you fly: eSIM purchase and activation pages may be hard to reach from inside China. Install it before boarding and it works the moment you land.
Getting a Chinese SIM Card on Arrival: The Real-Name Process
For stays of several weeks or more (say, post-surgery follow-ups), a local SIM is the most economical, and a Chinese phone number makes local contact easy:
Take your original passport to an airport counter or a carrier shop (China Mobile, China Unicom and China Telecom all serve foreigners).
Complete real-name registration — mandatory for all mobile services; some counters also run a facial verification.
Make sure your phone is carrier-unlocked; pick a data plan and activate on the spot.
Keep the new number handy: it is how local clinics, ride-hailing and delivery services will reach you.
Note that mainland carriers' eSIM support for foreign passports is limited — a physical SIM is the safer route.
Hotel Wi-Fi: A Backup, Not Your Main Connection
Hotel Wi-Fi exists, but treat it as a backup: public networks are unstable, quality varies widely between properties, and free Wi-Fi inside hospitals is often limited as well. Do not rely on Wi-Fi for important medical communication — keep usable mobile data.
Payments: Binding International Cards to Alipay and WeChat Pay
In China, QR-code payment covers nearly everything — convenience stores, taxis, self-service kiosks at hospital payment counters. The mainstream route for foreign passport holders:
Download Alipay or WeChat and register with your international phone number.
Under payment settings, bind an international credit/debit card such as Visa or Mastercard.
Scan the merchant's QR code to pay, or show your own code for the merchant to scan.
Limits and fees (per the two platforms' published policies for international cards): since March 2024, the limit is US$5,000 per transaction and US$50,000 cumulative per year; WeChat's official guide lists a ¥6,500 per-transaction cap for some scenarios. Transactions of ¥200 or less are exempt from fees; above ¥200 a fee of about 3% usually applies. Actual availability varies by card and verification status — for large hospital deposits or surgical fees, confirm the payment method with the hospital's international department first; hospitals generally also accept card payments and bank transfers.
QR payment acceptance is extremely widespread, but do not run your cash down to zero: carry a few hundred yuan in banknotes for the rare place that cannot scan or where the system is offline.
Payments and Communication at the Hospital
Outpatient payment: most hospitals accept card payment at the counter plus self-service kiosks or QR scanning; kiosk interfaces are mainly Chinese — if you cannot find English, ask the guidance desk or the international department for help.
Inpatient deposits: some hospitals require an advance deposit, usually paid at the counter or by transfer; for large amounts, confirm the channel and limits in advance.
Reports and follow-up booking: many hospitals run their own mini-programs inside WeChat, mostly in Chinese — let a companion or your service provider handle the navigation.

Essential Apps for a Medical Trip
Translation: an app with camera and voice translation is a necessity — medication inserts, test reports, menus can all be photographed and translated; download the offline language packs before departure.
DiDi: the default ride-hailing app, with an English interface, registration via international phone number, and direct support for international cards such as Visa/Mastercard — no Chinese bank card required.
Maps: Amap and Baidu Maps have the most complete data but mainly Chinese interfaces; Google Maps' coverage and navigation data inside mainland China are limited, so treat it as a supplement. Before departure, save the hospital, hotel and pharmacy locations in Amap/Baidu.
Food and grocery delivery: Meituan and Ele.me have broad coverage, but registration and payment are not always smooth with a foreign number or card; it is easier to let a companion place orders. Many local services depend on a Chinese phone number — another reason a local SIM adds value.
Emergency Numbers and Where to Get Help
120 — ambulance; 110 — police; 119 — fire. In big cities the 120 line is mainly Chinese; ask hotel front desk staff, a companion interpreter or MyMedVia to relay the condition and location.
Save the international department phone number of your hospital — most have English-speaking staff.
Keep the emergency contact details of your country's embassy or consulate in China.
The 24-Hours-Before-Departure Checklist
Activate your travel eSIM or roaming plan and confirm coverage for the whole trip.
Download offline maps (save the hospital and hotel in Amap/Baidu; Google offline maps as a supplement) and your translation app's offline language packs.
Bind your international card in Alipay/WeChat and make one small test payment.
Screenshot or print key medical documents (diagnosis, imaging reports, medication list) — do not keep them only in the cloud.
Save in your phone: 120/110, the hospital international department, your embassy, and MyMedVia's contact details.
Exchange a small amount of cash in yuan (a few hundred) for places that cannot scan.
