流量永不过期
eSIM balance that never expires
Jetogo
旅行 eSIM 你买过吧？
没用完的流量就这么没了
这个人觉得不对劲，自己做了一个
You bought a travel eSIM, came home with
2GB left — gone forever. One dev thought
that was dumb, so he fixed it
充值制，不是流量包
Credit, not data packs
市面上全是 3GB / 30 天这种套餐
卖的是倒计时
Jetogo 不一样——你充值进去
用一点扣一点，余额永远在
一年飞三次的人
再也不用每次重新算要买多少
Every other eSIM sells you '3GB, 30 days'
— a countdown. Jetogo is a wallet: add
$5 to $50, deduct per-use, balance stays forever
If you fly three times a year, you
stop re-buying and re-calculating every single trip
★ SIGNAL 1
不频繁出行的人，要的不是便宜
Infrequent travelers don't need cheap
品味就在这：大多数旅行 eSIM 在卷价格
但偶尔飞的人真正的痛点不是便宜五毛钱
是那种'买了 5GB 结果只用了 1.2GB'的心疼感
Jetogo 直接取消了这个博弈——没有套餐
没有过期，用多少算多少
The product sense here: every travel eSIM is
racing to the bottom on price. But the
real pain for someone who flies twice a
year isn't saving 50 cents — it's buying
5GB and using 1.2GB. Jetogo kills the entire
decision: no packs, no expiry, pay for exactly
what you use
★ SIGNAL 2
Claude Code 撑起一个真业务
A real business, built with Claude Code
HN 标题里直接写的：built with Claude Code
这不是个 demo
这是个真的在收钱的产品——135 个国家的运营商对接
实时计费系统
都是 AI 辅助开发的
敢这么写标题，说明他自己对这件事有信心
The HN title says it straight: 'built with
Claude Code.' This isn't a demo — it's
a product charging real money across 135+ countries
with carrier integrations and real-time billing. Publishing that
in the title takes confidence
作者 smoovb 没有藏着掖着
标题就把 AI 辅助开发说了出来
不是'革命性创新'
就是一个很实际的描述——长期有效的数据 eSIM
用 Claude Code 写的
朴素，但真实
Author smoovb didn't hide it — put it
right in the title. No 'revolutionary breakthrough,' just
a plain description: long-term data-only eSIMs, built with
Claude Code. Plain, but honest
