Phone number, apps, and identity friction
Last reviewed: 2026-05-24
Reader intent: Build the digital identity stack that makes daily life in China possible for a retired parent, in the right order, with the right names on each account, so that nothing breaks at the hospital pharmacy counter at 8pm on a Tuesday.
Plain-English answer: A mainland SIM card with the parent’s own passport on the contract is the single most important digital setup item. Without it, banking, hospital apps, Alipay verification, food delivery, property management, package pickup, and WeChat recovery all break. The setup has to be done in person with the parent and their passport at a carrier shop, and the order in which you set things up matters more than most families realise.
Why the phone number is the hinge of the entire digital life
Almost every important Chinese app uses the mainland phone number as the primary identity. Lose the SIM, change carriers without porting, or have the wrong name on the contract, and the parent loses access to:
- Alipay (支付宝), which sends transaction verification codes to the bound number
- WeChat (微信), which uses the bound number as the trusted recovery channel
- The hospital appointment app, which requires SMS confirmation for every booking
- The bank app, which sends OTPs for every transfer above CNY 2,000
- Property management mini-programs, which text package pickup codes and gate access
- The food delivery and grocery apps (Meituan, Hema, Dingdong) used daily
- Government service portals for visa renewal, tax filing, and health records
Roaming on a home-country SIM looks like a workaround for the first week. By day ten, the hospital app refuses an SMS code from a +1 or +61 number. By day fourteen, WeChat asks for a SIM-based device verification that the home SIM cannot satisfy. By day twenty, the parent is locked out of the bank app. There is no manual override that does not require physical presence at the bank branch, a fresh facial-recognition session, and the original passport.
The mainland SIM is not a nice-to-have. It is the substrate.
The three carriers and what they offer
| Carrier | Strengths | Plan style for a retiree | Where to buy |
|---|---|---|---|
| China Mobile (中国移动) | Best rural coverage, biggest network, most retail footprint | CNY 30, 60/month for 5, 20 GB plus 100 minutes | Green-and-white branded shops, on most commercial streets |
| China Unicom (中国联通) | Strong in tier-1 cities, better international roaming, often best 5G | CNY 30, 60/month for 10, 30 GB | Red-and-white branded shops |
| China Telecom (中国电信) | Best fixed-line plus mobile bundle, strong in southern cities, good campus coverage | CNY 20, 50/month for 5, 15 GB | Blue-and-white branded shops |
For a retired parent who mostly uses WiFi at home and the helper’s hotspot when out, the cheapest CNY 30/month plan is enough. Top up monthly via Alipay or set auto-recharge from the bank account once it is open. If the parent will travel frequently within China, Mobile is the safer default because of rural coverage on the way to feeder cities. If the parent lives in a tier-1 city and uses video calls heavily, Unicom usually has the better speeds.
Do not chase the cheapest possible plan or the unlimited-data promotional plans. The CNY 5/month “internet of things” SIMs sold online are real-name-registered to the reseller, not to the parent, and they break app verification within weeks. Buy from the official carrier shop, with the parent present, with their passport.
Setup process at the carrier shop, step by step
The parent must be physically present with their passport. Adult-child translation help is welcome but not required at staffed shops in tier-1 cities; English-capable staff are common at Shanghai, Beijing, Guangzhou, and major airport branches. Expect the following sequence:
- The counter clerk scans the parent’s passport.
- A facial photo is taken at the counter; the system cross-checks against the passport.
- Plan selection happens at the counter. Pick the simplest monthly plan that covers expected use.
- SIM is activated within 10 minutes; the new number is printed on a receipt.
- First top-up is paid at the counter, typically CNY 100 to CNY 200.
- The clerk hands over the SIM card, a printed contract, and the receipt; the number is real-name-registered to the parent.
This last point matters most. Many apps will reject SIMs registered to someone else, including a child or a Chinese relative. The parent’s name on the contract, the parent’s face in the carrier’s verification database, the parent’s passport number in the system; these three have to match the names on Alipay, WeChat, the bank account, and the hospital app for everything downstream to work.
If the parent is at the airport on arrival, the airport carrier kiosks complete this in 15 minutes. Worth doing immediately, even though airport kiosk rates are slightly higher than city shops. The cost of the convenience is CNY 20 to CNY 50; the cost of arriving in the city without a SIM is one wasted afternoon at a carrier shop with luggage.
The two-hour app install ritual on day one
Block two hours, sit next to the parent, and install everything together. Do not let the adult child install everything remotely under their own account; the parent must own their own logins, with their own passport on file for verification, with their own face in the recognition database.
| App | What it does | Identity required |
|---|---|---|
| WeChat (微信) | Messaging, family group, payments, mini-programs for almost every service | Mainland number plus facial verification |
| Alipay (支付宝) | Payments, transit, hospital apps, government services portal, utilities | Passport upload plus facial verification |
| Amap (高德地图) | Maps, taxi, real-time bus, walking directions | Mainland number |
| Didi (滴滴) | Taxi alternative with broader driver pool than Amap’s built-in | Mainland number |
| Meituan (美团) | Food delivery, groceries, pharmacy delivery, movie tickets | Mainland number |
| Hospital app of choice (健康160, 微医, or the hospital’s own mini-program) | Appointment booking, queue position, payment, results retrieval | Mainland number plus passport |
| Bank app (BOC, ICBC, CCB) | Balance, transfers, card recovery, salary deposits | Mainland number plus bank card |
| Property management app (varies by compound) | Building gate access, package pickup, repair requests, fee payment | Mainland number |
| Pleco | Chinese-English dictionary, essential for medical translation | None |
| eHealth Card (国家医保电子凭证, via Alipay or WeChat mini-program) | Unified health insurance ID, links to LTCI if eligible | Real-name verified Alipay or WeChat |
After installation, do a verification pass on each app: log out, log back in, confirm the SMS code arrives, confirm facial recognition works. Catching a broken verification on day one is a one-hour fix at the carrier shop. Catching it on day forty, when the parent needs to book an urgent cardiology appointment, is a crisis.
The order in which to set things up
The order is not optional; some steps depend on previous steps. Block the first week of the trial stay accordingly.
- Day 0 (arrival): Buy SIM at airport carrier kiosk. Activate within 24 hours.
- Day 1: Register accommodation at the local 派出所 (police station). The accommodation registration slip is required for the bank account.
- Day 1, 2: Install WeChat and Alipay; real-name verify both with the passport. Verification takes 24 to 48 hours.
- Day 3, 5: Visit Bank of China or ICBC branch in a tier-1 area for the debit card. Bring passport, accommodation registration slip, mainland SIM. Card is mailed within 5 to 14 days.
- Day 5, 7: Install hospital app for the target hospital. Real-name verify with passport. Test-book a non-urgent appointment to confirm the flow works.
- Day 7, 10: Install property management app for the building. Register for gate access and package pickup. Confirm payment flow for the monthly fee.
- Day 10, 14: Set up auto-recharge for the SIM via the bank card or Alipay. Set up auto-pay for utilities once the first bill arrives.
- Day 14, 21: Migrate any home-country apps that still bind to the old number (WhatsApp, banking, two-factor codes) to use authenticator apps or the new mainland number.
The password vault that prevents catastrophe
By the end of the first month, the parent has logins for at least 15 services. By month three, 25 or more. None of these can be reliably remembered. A password manager is not optional.
Set up 1Password Families or Bitwarden on day one. Shared access between the parent, the primary mainland contact, and the abroad coordinator. Every credential goes in: app password, bank PIN, SIM PIN, building gate code, WeChat backup phrase, Alipay payment password, hospital app login, property management code.
Two things to verify when picking the manager:
- It works on the parent’s phone and accepts the parent’s facial unlock.
- It can store mainland phone numbers and SMS verification codes (some managers strip non-Latin characters).
The single biggest failure mode in month six is the dropped phone with no backup access. The password vault, plus the backup phone with the SIM ready to swap, makes that failure mode a two-hour inconvenience instead of a two-week crisis.
Common mistakes
- Adult child uses their own passport for the SIM so they can manage it remotely. Apps will then reject the number because the real-name registration does not match the parent’s passport on file at Alipay or the bank. The fix is a fresh SIM, registered to the parent, plus re-verification of every downstream account. Hours of unnecessary work.
- Parent loses the SIM PIN and cannot unlock the phone after a reboot. Write the PIN in the password vault on day one, and on a card in the emergency binder.
- WeChat bound to the old home-country number. When the home number is cancelled, recovery becomes painful. Migrate the bound number to the mainland SIM in week 2, while the home number still works for the cross-verification SMS.
- Password manager not set up. Six months later, no one remembers the bank app password and the parent has been quietly avoiding using the app.
- No backup phone. A dropped phone breaks everything for 3 days while a replacement is sourced and apps reinstalled. Keep a backup device in the apartment with the same Apple ID or Google account, ready to receive the SIM.
- Buying an “unlimited data” promo SIM online. Real-name registered to the reseller, not the parent. App verification breaks within a month. Always buy from the official carrier shop with the parent present.
- Skipping the eHealth card setup. The 医保电子凭证 unifies insurance reimbursement across hospitals and links to long-term-care insurance where eligible. Set it up during the first hospital visit; the registration counter staff can guide.
What to verify locally
- Whether your target city has English-capable carrier staff (yes in tier-1, often no in tier-3); if not, bring a Mandarin-speaking helper or the property management contact to the carrier shop.
- Whether the parent’s phone is unlocked and supports the Chinese carrier bands (most modern unlocked phones do; iPhones bought in the US are reliably good; some Android phones bought on carrier contract in the home country need an unlock first).
- Whether the home-country mobile provider charges a release fee to free the parent’s phone for international SIMs.
- Whether the target apartment building’s property management app exists in English (most do not; plan for translation help during setup).
- Whether the target city’s eHealth card supports cross-province use; some pilot cities (Shanghai, Hangzhou) link to Beijing, others do not.
