API primero, hasta la SIM.

Everything the dashboard does is an API call: buy data, provision eSIMs, rent numbers, send SMS, configure Tele Agent. Built for human developers — and for autonomous AI agents.

Disponible hoy

The developer platform is already open.

Sin llamadas comerciales, sin proyectos bloqueados por humanos: inicia sesión y crea tus propias claves API. Los endpoints de producto (catálogo, pago, números, Tele Agent) están activos — todo lo que sigue funciona ahora mismo.

Claves API de autoservicio

Inicia sesión con Firebase y crea claves esk_live_… al instante — con alcance a un proyecto (production, test, experiment), almacenadas como hash y revocables en una llamada.

Endpoints HTTPS, firmas HMAC-SHA256 por endpoint (estilo Stripe t=…,v1=…), entrega al menos una vez con reintentos, dead-lettering y reenvío. Eventos de facturación, provisión de números, portabilidad, llamadas, SMS, claves y KYC.

API de portabilidad de números

draft → information_required → pending → completed. La API te dice exactamente qué campos necesita cada país antes de enviar — el envío es fail-closed hasta que el operador completa la incorporación.

Registro KYC

Recopila los documentos de identidad que exigen los operadores por país. La verificación permanece honestamente en pending_verification hasta que se configure un proveedor de verificación — nunca un falso «verificado».

Página de estado honesta

Estados de los componentes derivados en vivo de la configuración del servicio — nunca porcentajes de disponibilidad inventados.

Desarrolladores de esimgomobile: the full picture

The short version: prepaid travel eSIMs across 195 destinations, installed by QR code in two minutes, managed from a dashboard, with an AI agent on call when you need a human-style answer fast.

Everything on this page exists to answer one question well: how does esimgomobile fit into your trip? The sections below go deep so you never need a second tab.

The long version is the rest of this page — plans, mechanics, edge cases and honest trade-offs, written the way we'd explain it to a friend.

Explainer

How it works, step by step

  1. Choose data that fits the trip
    • Short city break? 5 GB. Two weeks with maps and video calls? 20 GB. Working remotely or hotspotting? 50 GB or Unlimited.
    • Every plan shows exactly what you get — no asterisks.
  2. Install in two minutes
    • Buy, scan the QR code, done. The whole thing happens on your phone, wherever you are.
    • Install days before you fly or minutes before boarding — your call.
  3. Switch on and go
    • Enable the eSIM line in settings when you arrive. It connects to the fastest local partner network on its own.
    • Your home number keeps working for calls and texts on your physical SIM if you keep it active.

Explainer

Good to know

  • Charge your phone before long travel days; weak signal areas drain batteries faster.
  • Buy and install your eSIM before departure — airport Wi-Fi is the worst place to set up connectivity.
  • Hotspot sparingly: one laptop tethered all day can burn through a week of phone data.
  • If a page won't load, toggle airplane mode for ten seconds — it forces a fresh network attach.
  • Check that your phone is carrier-unlocked before you buy any eSIM — locked phones can't add one.
  • Keep your home SIM active for two-factor codes from your bank; run data on the eSIM line.

These are the details that separate a smooth trip from a stressful one — small, unglamorous, and worth more than any feature list.

Explainer

Why travelers switch

Roaming bills taught a generation to fear their phones abroad. The eSIM generation simply never learned that fear — data is prepaid, visible and finite.

The Tele Agent closes the remaining gap: a question at midnight in a foreign terminal gets an answer in seconds, not a support ticket.

And because everything is prepaid through Amazon Pay, the commercial relationship is simple: you pay for data, you get data, it ends when it ends.
