什么是

eSIM 旅行设置是一项用于国际旅行的离线规划技能，可帮助你选择 eSIM、估算流量需求、比较旅行 eSIM 与运营商漫游和当地 SIM 选项，并准备实用的出发清单。它还会检查常见的旅行身份验证风险，包括银行短信验证码、新设备登录验证以及 WhatsApp 号码验证。
作为 Openclaw Skills 的一部分，它将连接规划与账户安全整合到一个行前工作流程中。其核心建议是：保留本国 SIM 卡的启用状态以接收重要消息，同时使用旅行 eSIM 上网，并关闭数据切换，以减少意外漫游费用。

应用场景

为即将到来的国际旅行规划连接方式和流量需求。
比较旅行 eSIM、运营商漫游套餐或机场 SIM 卡。
为可能适合使用区域 eSIM 的多国旅行做准备。
检查银行、电子邮件、iCloud 或 WhatsApp 验证是否可能在境外失败。
制定出发前 T-48h、T-24h 和机场当天的清单。
查看目的地特定事项，例如中国的 VPN 访问，或巴西和土耳其的 IMEI 注册规定。
为首次国际旅行的家庭成员准备手机。

工作原理

输入目的地、旅行时长和使用情况，以估算流量需求，并获取本地、区域或全球 eSIM 建议。
查看目的地特定说明并遵循双 SIM 卡策略：让本国 SIM 卡保持可接收短信的状态，并将旅行 eSIM 设为默认数据线路。
按账户逐一检查银行、主要电子邮件、iCloud 或 WhatsApp 等重要服务的双重验证，然后在出发前完成建议的修正措施。
根据旅行时长、流量需求和漫游套餐详情，比较 eSIM、运营商漫游和当地 SIM 卡的费用。
在 T-48h 安装旅行 eSIM，完成 T-24h 准备事项，并遵循 T-0 机场清单。
着陆后关闭飞行模式，让旅行 eSIM 连接网络；保留本国 SIM 卡以接收消息，并测试消息收发和重要账户登录。

配置指南

此技能使用 Python 3 和标准库，可离线运行，文档未要求安装第三方软件包。请在技能目录中运行命令，该目录下提供 scripts/esim_planner.py。
python3 scripts/esim_planner.py plan --destination Japan --days 12 --profile maps-heavy

eSIM Travel Setup

Overview

International travel breaks phones in two predictable places: connectivity (which SIM, how much data, what it costs) and authentication (bank sends an OTP to a number that just stopped receiving SMS; Google challenges a login from a "new device" while you're standing in an airport). The second failure is the expensive one — locked out of money and mail abroad, people lose days.

This skill plans both, before departure:

plan — destination + days + usage profile → data sizing, eSIM type recommendation (local vs regional vs global), dual-SIM strategy, and country gotchas (Great Firewall, IMEI registration, VoIP blocks).
twofa — account-by-account travel-auth risk audit: what breaks, and the exact pre-departure fix (backup codes, pre-trusted devices, receive-only roaming for the home SIM).
costs — eSIM vs carrier roaming bundle vs airport SIM, with the break-even logic for trip length.
checklist — printable T-48h / T-24h / T-0 (airport) sequence, including the landing failure protocol.

Pure stdlib, offline.

When to Use

Any international trip: "what's my connectivity plan?" (2+ weeks out ideal)
"Should I buy an eSIM or use my carrier's $10/day travel pass?"
"Will my bank's 2FA work abroad?" (the question people ask too late)
Multi-country trips (regional eSIM choice)
"Going to China/Brazil/UAE/Turkey — anything special?" (gotcha database)
Setting up a family member's phone before their first trip abroad

Don't use for: domestic travel (home network, no problem), permanent expat relocation (residency, local contracts, number porting — different domain), or corporate MDM-managed devices (your IT department owns the auth model).

How It Works — Numbered Steps
Size the data honestly:

python3 scripts/esim_planner.py plan --destination Japan --days 12 --profile maps-heavy

→ 4.8 GB, Asia regional group, dual-SIM strategy, Japan notes.
Audit the accounts that matter — minimum bank + primary email:

python3 scripts/esim_planner.py twofa --bank --email-google --icloud

Execute every BEFORE-DEPARTURE line. Print backup codes on paper.
Price the three options:

python3 scripts/esim_planner.py costs --destination Mexico --days 10 \

--data-gb 5 --roaming-bundle 10 --roaming-gb 2

Buy and INSTALL the eSIM at T-48h (activation triggers on first connect at the destination — installing early is free and removes airport risk).
Work the checklist:

python3 scripts/esim_planner.py checklist

T-48h → T-24h → T-0, including the dual-SIM toggle sequence on landing.
On landing: airplane mode off → travel eSIM attaches in ~2 min → home SIM stays on for SMS receive. Send one test message; confirm bank app login.
The Two-SIM Doctrine (core of the skill)
Home SIM stays ACTIVE, roaming, receive-only. Bank OTPs, WhatsApp verification, iMessage/RCS re-confirmation all target your number. Receiving SMS abroad is free or near-free on major carriers; NOT having it can cost you account access.
Travel eSIM carries the data. Default-data line = travel eSIM.
Data switching OFF. Phones love to silently burn the home SIM's roaming data at $15/MB when the travel line hiccups.
Never swap the home SIM out on a single-SIM phone — that's what airport physical-SIM kiosks still talk people into.

Common Pitfalls

Buying the eSIM at the airport. Install at T-48h; airport wifi + provider app + activation queues are a bad combo at 6 AM.
Disabling the home SIM "to avoid roaming charges." The #1 self-inflicted 2FA lockout. Receive-only SMS is not a charge risk on mainstream carriers — verify once with your carrier, then leave it on.
Relying on SMS-only bank auth. If your bank supports app-based or TOTP 2FA, enroll BEFORE the trip; SMS abroad is single-point-of-failure.
No offline backup codes. Google/iCloud new-device challenges abroad can require codes you printed never. Paper, two locations, not photos.
China VPN procrastination. VPN apps vanish from app stores once your device is inside China. Install and test at T-24h.
Brazil IMEI / Turkey registration rules. Long-stay registration rules silently kill foreign phones after a grace period — the gotcha database flags both.
iMessage/SMS "activation failed" loops. Tied to the home number; fixed by keeping home SIM reachable. eSIM data alone doesn't cover it.
Testing nothing. Every MFA method should be exercised on the travel device before departure. A TOTP seed that synced to your old phone only is a lockout with extra steps.

Example

Trip: 12 days in Japan, bank that uses SMS OTP, WhatsApp-dependent family.

$ plan --destination Japan --days 12 --profile maps-heavy
→ 4.8 GB; Asia regional eSIM if hopping; dual-SIM doctrine printed.

$ twofa --bank --whatsapp
→ [10/10] bank: enroll app-2FA or keep home SIM roaming for SMS;
[5/10] WhatsApp: number re-verification needs SMS — home SIM stays on.

$ costs --destination Japan --days 12 --data-gb 5 --roaming-bundle 12
→ eSIM ~$23 vs roaming pass ~$144 → eSIM wins 6x.

$ checklist → install eSIM T-48h, codes on paper, bank travel notice,
landing sequence: airplane off → eSIM attaches → test bank login.
