核心观点
**Cannot receive SMS verification in China?** First restore the **home SIM**—that is the OTP line. **Usually you do not need a Chinese +86 number** for **3–14 day** tourism. Pattern that works: **home SIM for SMS** (bank/Alipay/WeChat OTP) + **mainland China data eSIM** for maps/Didi/QR. Buy **+86 SIM** only for long stays, blocked home SMS, or repeated failures after that setup.

Detailed Answer
Read this if you need yes/no on +86—not eSIM shopping (eSIM essential) or full connectivity guide (mobile data guide).
| Component | Typical tourist setup |
|---|---|
| Home number (+44, +1, …) | SMS OTP — keep SIM on |
| China eSIM | Data only — maps, Didi, wallet refresh |
| +86 Chinese SIM | Optional for short trips |
Tourist eSIM ≠ Chinese phone number. Data-only plans do not give +86 SMS—that is normal.
When +86 is worth buying
- Weeks–months in China
- Home carrier blocks roaming SMS (test OTP before flying)
- Employer/work apps require +86
- OTP still fails after bank + app fixes (community +44 story)
What does NOT require +86
- Alipay/WeChat with international registration (Alipay question)
- Scanning merchant QR (needs data, not +86)
- Amap navigation on cellular
Not covered here: eSIM brand comparison, APN troubleshooting → eSIM essential.
适合谁
- eSIM-only planners who might disable home SIM
- “Must I buy airport SIM before Alipay?” (usually no)
- Dual-SIM owners labeling lines wrong
下一步
- eSIM essential — choose eSIM vs roaming vs local SIM.
- Mobile data guide — install + arrival test.
- App checklist — wallets after connectivity plan is set.

常见问题
Why don’t I receive SMS verification in China?
Usually because the **home SIM is off**, data roaming ate the line, or the eSIM replaced the SMS line. Keep **home number on** for OTP; use China eSIM for **data only**.
Do I need +86 for Alipay?
**No** for most short trips.
Does tourist eSIM include +86?
Usually **no**.
