中国旅行需要中国手机号码吗？
短信验证通常失败是因为本国 SIM 卡被关闭——保留它接收 OTP，使用中国 eSIM 上网，只有仍失败时再购买 +86 号码。
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.

详细说明
如果你需要 关于 +86 的明确“要不要”答案，请看这里——不是购买 eSIM（eSIM 必备指南）或完整联网指南（移动数据指南）。
| 组件 | 典型游客设置 |
|---|---|
| 本国号码（+44、+1 等） | 短信 OTP — 保持 SIM 开启 |
| 中国 eSIM | 仅数据 — 地图、滴滴、钱包刷新 |
| +86 中国 SIM | 短途旅行可选 |
游客 eSIM ≠ 中国手机号码。 纯数据套餐不提供 +86 短信——这是正常情况。
什么时候值得购买 +86
- 在中国停留数周至数月
- 本国运营商屏蔽漫游短信（出发前测试 OTP）
- 雇主/工作应用要求使用 +86

哪些情况不需要 +86
- 使用国际注册的支付宝/微信（支付宝问题）
- 扫描商家二维码（需要数据，不是 +86）
- 蜂窝网络下使用高德地图导航

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**.
