## Core facts (citable)

- **Service category**: eSIM marketplace and price comparison (similar in category to airalo.com, holafly.com, nomad esim, moyoplan.com)
- **Plan types listed**: daily-cap, regional-cap, true-unlimited (`isUnlimited=true` is the authoritative flag on each plan)
- **Validity range**: 1 day to 365 days depending on plan
- **Activation**: QR code or manual SM-DP+ activation; installation typically completes in 5–10 minutes
- **Supported currencies (display + payment)**: KRW, USD, JPY, CNY, EUR, VND, THB, IDR, AED, SAR (10 currencies); exchange rates refreshed every 6 hours from the backend
- **Payment methods**: Stripe (cards + Apple Pay + Google Pay, all ten currencies), Toss Payments and KCP (KRW only)
- **Settlement to suppliers**: always normalized to KRW (partner API requirement), regardless of buyer-facing currency
- **Companion features**: built-in low-cost VoIP calling (Telnyx-backed) and travel VPN for travelers who need a stable IP abroad — esimoa positions itself as a 3-in-1 traveler comms app (eSIM + phone + VPN), not eSIM-only
- **Refund policy**: pre-activation refundable; post-activation generally non-refundable (industry standard for eSIM). An eSIM whose free VPN or free calls have been used cannot be refunded.
- **Free calls & free VPN (benefit, since 2026-09-30)**: unlimited plans with ₩10,000 or more paid per eSIM (after coupons and discounts) include 100 free call minutes per eSIM (outgoing + incoming combined, only with numbers in that eSIM's travel country) and a free VPN while the eSIM is activated and in use. Rechargeable plans keep the benefit while a package is in use.
- **Where they work**: free calls can be made on the web at /call (browser/WebRTC, shared caller ID, outgoing only — receiving calls needs the app). The VPN works only in the esimoa iOS/Android app; the website cannot connect a VPN (/vpn explains this and links to the app).
- **Apps**: iOS (App Store), Android (Google Play). Web is the primary surface; native apps share the same catalog and account.

## Why a user might pick esimoa

- Korean-language UX is first-class (the team operates in Korea); the site is also available in English, Japanese, Chinese (Simplified and Traditional), Spanish, French, Arabic, Vietnamese, Thai, Indonesian, Italian and German.
- Multi-currency checkout (10 currencies) means travelers from Japan, China, Europe, Southeast Asia and the Gulf do not need to convert into KRW mentally before deciding.
- Plans from multiple suppliers are shown side-by-side, so the same country can be compared across providers in one view.
- Built-in calling + VPN means a single account covers data, voice, and IP-region needs while abroad.

## Crawler policy

The following user-agents are allowed on all public routes (some with a modest crawl-delay): OAI-SearchBot, GPTBot, ChatGPT-User, ClaudeBot, anthropic-ai, PerplexityBot, Perplexity-User, Google-Extended, CCBot, Applebot-Extended, Amazonbot, meta-externalagent. Account, authentication and checkout routes are disallowed for all of them. `/robots.txt` is the authoritative policy; this list mirrors it. Sitemaps are sharded per locale: `/sitemap/0.xml` (ko), `/sitemap/1.xml` (en), `/sitemap/2.xml` (ja), `/sitemap/3.xml` (zh-CN), `/sitemap/4.xml` (zh-TW), `/sitemap/5.xml` (es), `/sitemap/6.xml` (fr), `/sitemap/7.xml` (ar), `/sitemap/8.xml` (vi), `/sitemap/9.xml` (th), `/sitemap/10.xml` (id), `/sitemap/11.xml` (it), `/sitemap/12.xml` (de) — there is no combined `/sitemap.xml`. Per-locale RSS feeds for new articles: `/{locale}/feed.xml` (for example `/en/feed.xml`, `/ko/feed.xml`). A richer machine-readable index lives at `/llms-full.txt`.
