iPhone Duo 买哪版？
eSIM 时代的地区版本选购器 Which iPhone Duo to buy?
A region & eSIM picker for the eSIM era

iPhone Duo 全球取消实体卡槽，18 Pro 国行改成「单卡 + eSIM」。留学生、差旅党、两地跑的人，买错版本可能意味着回国装不上国内号码。这里用三个问题帮你算清楚：买哪个地区版、用什么 SIM 组合、去哪个运营商 App 开通。 iPhone Duo dropped the SIM tray everywhere, and the China-market 18 Pro moved to “one nano-SIM + eSIM”. Students, frequent flyers and people living across two countries can buy the wrong version and find their home number won't install. Three questions here settle which region to buy, what SIM combo to run, and which carrier app to open.

选一台机器、一个所在地，把两张卡「装」进去。模拟器按 Apple 官方 SIM 规格和运营商政策判断能不能用，而不是凭感觉。Pick a phone and where you are standing, then “install” two lines. The simulator checks Apple's official SIM specs and carrier policy, not vibes.

关键规则：国内运营商的 eSIM 只能装在国行机型上（Duo 是 A3721）。美版 / 港版 / 日版 Duo 在大陆无法开通移动、联通、电信的 eSIM；而且身处大陆时也无法安装任何境外运营商的 eSIM。The rule that matters: Chinese carriers' eSIMs only install on China-market models (Duo = A3721). A US / HK / JP Duo cannot activate China Mobile, Unicom or Telecom eSIMs on the mainland — and while physically in the mainland, no non-mainland eSIM can be installed either.

05 · Carrier apps

三大运营商出境速查卡The three Chinese carriers, on one card

开国际漫游本身免费，贵的是流量。三家的开通入口、短信指令和推荐 App 如下，出发前 3 天办好。Enabling international roaming is free; the data is what costs. Activation paths, SMS commands and recommended apps below — do it 3 days before departure.

中国移动China Mobile 10086

开通漫游（长期）Enable roaming: GMKT → 10086
30 天临时30-day temp: GMKT30 → 10086
关闭Disable: GMQX → 10086
  • App「中国移动」→ 搜「漫游功能」→ 在线办理 → 国际漫游专区买目的地流量包search “漫游功能” → online activation → buy destination data packs in 国际漫游专区
  • App「无忧行」(JeGo)：移动国际的出境 App。境外流量包常有 6–8 折；开通后可在 App 内免费接听自己号码的来电和短信（对收验证码非常关键），新用户送回国通话分钟。China Mobile International's travel app. Data packs often 20–40% off; once set up you can receive calls and SMS to your own number inside the app for free — critical for verification codes — plus free minutes to China for new users.
  • 按量漫游约 ¥3–4/MB，等于不设上限地烧钱，一定买包。Pay-as-you-go roaming runs about ¥3–4/MB — always buy a pack.

中国联通China Unicom 10010

开通漫游Enable roaming: KTGJMY → 10010
  • App「中国联通」→ 搜「出境漫游专区」→ 开通 → 同页购买流量包（示例：日本 7 天、欧洲 15 天多档位）search “出境漫游专区” → enable → buy packs on the same page (e.g. Japan 7-day, Europe 15-day tiers)
  • 联通是最早给 iPhone Air / 17e 开 eSIM 的一家；Duo 的 eSIM 需带身份证和手机到营业厅办理。Unicom was first to support eSIM on iPhone Air / 17e; Duo eSIMs require an in-store visit with ID and the phone.
  • 拨 10010 转人工说「开通国际漫游」也可以。Calling 10010 and asking an agent for 国际漫游 also works.

中国电信China Telecom 10001

开通漫游Enable roaming: KTGJMY1 → 10001
关闭Disable: 6763 → 10001
  • App「中国电信」→ 查询办理 → 全部服务 → 国际/港澳台 → 开通并选包查询办理 → 全部服务 → 国际/港澳台 → enable and pick a pack
  • 按区域计费：日韩 / 东南亚 / 欧洲 / 北美四档，北美最贵（约 ¥4.2/MB）。Zone pricing: Japan-Korea / SE Asia / Europe / North America, with North America the priciest (~¥4.2/MB).
  • eSIM 办理支持在 App 预约营业厅，再带证件到店。eSIM: book a store in the app, then bring ID in person.

旅行 eSIM 与 Duo 的相处规则Travel eSIMs and the Duo

  • 日本 7 天旅行 eSIM 通常 ¥38–58，比按量漫游便宜 90% 以上。A 7-day Japan travel eSIM is typically ¥38–58 — over 90% cheaper than pay-as-you-go roaming.
  • 国行机：出境后开启定位服务才能安装当地运营商 eSIM；再装第二张旅行 eSIM 前需删掉上一张。China-market phones: turn on Location Services abroad before adding a local eSIM; delete the previous travel eSIM before adding another.
  • 任何机型在大陆境内都装不了境外 eSIM——回国前先装好、进大陆后再启用。No model can install a non-mainland eSIM while inside the mainland — install before entering, enable after.
  • Duo 可存 8 张以上 eSIM、同时激活 2 张，适合把「国内主号 + 当地号」常驻，旅行 eSIM 轮换。Duo stores 8+ eSIMs with 2 active: keep “home number + local number” resident and rotate travel eSIMs.
06 · FAQ

那些千篇一律的攻略不会告诉你的What the copy-paste guides won't tell you

美版 Duo 回国能用国内号码吗？Can a US Duo run a Chinese number back in China?
不能直接装。三大运营商的 eSIM 只支持国行型号 A3721。可行的替代：① 港版运营商（如 CMHK、3HK）提供带内地号码/内地漫游的 eSIM，在香港开好带回；② 移动用户用「无忧行」App 在线接收自己号码的来电与短信；③ 换国行或港版 18 Pro（有实体卡槽）。注意「一号双终端」在跨境场景下并不可靠。 Not directly. The three carriers' eSIMs only support the China-market model A3721. Workarounds: ① Hong Kong carriers (CMHK, 3HK) sell eSIMs with mainland numbers/roaming — set it up in HK; ② China Mobile users can receive their own number's calls and SMS in the 无忧行 (JeGo) app; ③ switch to a CN or HK 18 Pro, which still has a SIM tray. “One number, two devices” is unreliable across borders.
国行 18 Pro 到底是几张卡？How many SIMs does the CN 18 Pro really take?
Apple 中国官网写的是：两个 nano-SIM，或一个 nano-SIM + 一个 eSIM，或两个 eSIM——也就是国行首次支持 eSIM，且可双 eSIM。港版规格为 nano-SIM + eSIM，支持双 eSIM。日版 18 Pro 据日本媒体为双 eSIM、无卡槽（与美版一致）。 Apple China's spec page says: two nano-SIMs, or one nano-SIM + one eSIM, or two eSIMs — the first CN iPhone with eSIM, dual-eSIM capable. HK spec: nano-SIM + eSIM with dual-eSIM support. Japanese media report the JP 18 Pro as dual-eSIM with no tray, matching the US model.
国内 eSIM 怎么开？能在 App 里开吗？How do you activate an eSIM in China? In the app?
目前只能到营业厅：带身份证（或护照）+ 手机本人办理，电信可先在 App 预约网点。线上自助开通尚未开放，所以留学生务必在出国前办好。 In-store only for now: bring your ID (or passport) and the phone; China Telecom lets you book the store in its app. Self-service online activation isn't available yet, so students must do this before leaving the country.
在美国怎么保住国内号码不掉线？How do I keep my Chinese number alive in the US?
国内线改最低「保号套餐」，开通国际漫游；iPhone 里把国内线的「数据漫游」关掉、蜂窝数据切到美国线，短信/来电保持双线可用。微信、支付宝的验证码绑定的是号码不是位置，能收到短信就够。 Downgrade the CN line to the cheapest keep-alive plan and enable international roaming; on the iPhone turn off Data Roaming for the CN line, set Cellular Data to the US line, and leave both lines on for SMS/calls. WeChat and Alipay codes are tied to the number, not your location.
港版 Duo 和港版 18 Pro，两地跑选哪个？HK Duo or HK 18 Pro for a two-city life?
如果你有内地实体卡又不想折腾 eSIM，港版 18 Pro（nano-SIM + eSIM）是最省心的组合：内地卡插槽、香港/美国号走 eSIM。港版 Duo 无实体卡槽，内地号码只能靠港版运营商的内地方案。价格上港版 Duo HK$17,499 ≈ $2,245，比国行便宜约 $150。 If you hold a mainland physical SIM and don't want eSIM hassle, the HK 18 Pro (nano-SIM + eSIM) is the low-friction combo: mainland SIM in the tray, HK/US number on eSIM. The HK Duo has no tray, so a mainland number must come through an HK carrier's mainland plan. Price-wise the HK Duo at HK$17,499 ≈ $2,245 is about $150 under the CN model.
Duo 值这个价吗？和 18 Pro Max 比少了什么？Is the Duo worth it vs. the 18 Pro Max?
Duo：7.6″ 内屏 + 5.4″ 外屏，254 g，Touch ID 侧键，48MP 主摄 + 48MP 超广角 + 12MP 2x 长焦，无 18 Pro 的可变光圈；卫星功能激活后免费两年。18 Pro Max：6.9″，249 g，Face ID，可变光圈主摄，视频播放 43–45 小时。Duo 比 Pro Max 贵 $700，买的是形态而不是影像。 Duo: 7.6″ inner + 5.4″ outer, 254 g, Touch ID side button, 48MP main + 48MP ultra-wide + 12MP 2x tele, no variable aperture; satellite features free for two years. 18 Pro Max: 6.9″, 249 g, Face ID, variable-aperture main camera, 43–45 h video. The Duo costs $700 more — you're paying for the form factor, not the camera.
