养一张海外 eSIM，多半是为了留住那个号码——收验证码、保住账号、维持一份联系方式。 但运营商有条不成文的规矩：连续一段时间没有任何计费行为，号码就会被回收。giffgaff 是约 180 天，各地储值卡从 30 天到 365 天不等。真正让人丢号的从来不是欠费，而是忘了。 eSIM 保号助手就干一件事：在你忘记之前提醒你，并让保号这件事一步完成。 【录一次，之后不用管】 选择运营商，保号周期和保号方式会自动带出来；确认上次保号的日期，这张卡就建好了。剩下的交给提醒。 【提醒写进系统日历】 建卡时会自动在到期前 7 天、3 天、2 天、1 天各写一条日历提醒。日历会通过 iCloud 同步到你所有设备——就算这个 App 半年没打开过，提醒也照样准时出现在你的 iPhone、iPad 和 Mac 上。 【一键完成保号】 打开卡片详情，点「去发短信」或「用 1KB 流量」，App 会实际产生一次计费行为。完成后到期日自动顺延一个周期，四条日历提醒整体重排，不用你手动改任何日期。 【看得见的台账】 每次保号都会记一条记录，日期和方式都在。过阵子想起来「我上个月到底保了没」，翻一下就知道。 【一眼看清轻重】 首页按紧急程度排序，最急的排在最前。剩余 7 天以内的卡会变红，其余是绿色。桌面小组件让你不打开 App 也能看到全部卡片的状态。 【你的数据只在你手机里】 没有账号，不需要注册，不联网上传。所有卡片信息都存在本机，卸载即消失。 —— 使用前请注意 —— • 提醒依赖系统日历，因此建卡时需要授予日历权限。如果在系统设置里关闭该权限，或手动删除了 App 创建的日历事件，提醒将不再生效。 • iOS 不允许 App 读取 eSIM 的运营商和到期信息，所有卡片信息需要手动录入。 • App 内置的保号周期为常见参考值，各运营商政策可能调整，请以运营商官方说明为准。

Verdict
The clearest difference is in-app purchases: eSIM保号神器 at none against Calendar Capture's 3. eSIM保号神器 also leads on iOS requirement (15.6 vs 17.0). Calendar Capture's advantage is update cadence (every 4 days vs fortnightly). On price, ads and device support there is nothing between them.
