API em primeiro lugar, até o 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.

Disponível hoje

The developer platform is already open.

Sem chamada de vendas, sem primeiro projeto liberado por humanos: entre e crie suas próprias chaves de API. Os endpoints de produto (catálogo, checkout, números, Tele Agent) estão ativos — tudo abaixo funciona agora mesmo.

Chaves de API self-service

Entre com Firebase e crie chaves esk_live_… na hora — com escopo de um projeto (production, test, experiment), armazenadas como hash e revogáveis em uma chamada.

OpenAPI 3.1, publicado

Todas as rotas ativas documentadas em um único arquivo legível por máquina — marcado para que geradores nunca finjam que uma rota funciona antes de funcionar.

Webhooks: com.esimgomobile.*

Endpoints HTTPS, assinaturas HMAC-SHA256 por endpoint (estilo Stripe t=…,v1=…), entrega pelo menos uma vez com backoff, dead-lettering e replay. Eventos de cobrança, provisionamento de números, portabilidade, chamadas, SMS, chaves e KYC.

API de portabilidade de números

draft → information_required → pending → completed. A API informa exatamente quais campos cada país exige antes do envio — o envio é fail-closed até a conclusão do onboarding da operadora.

Coleta de KYC

Colete os documentos de identidade que as operadoras exigem por país. A verificação permanece honestamente em pending_verification até que um fornecedor de verificação seja configurado — nunca um falso "verificado".

Página de status honesta

Estados dos componentes derivados ao vivo da configuração do serviço — nunca porcentagens de uptime fabricadas.

Developer surface

Four ways to build.

SDKs

Live: idiomatic JavaScript and Python clients covering every live route — keys, webhooks, porting, KYC, status. Tested, versioned, on GitHub.

Status: disponível

CLI

Live: the esim CLI scripts everything from the terminal — esim keys issue, esim webhooks register, esim portings create, esim kyc verify. Made for automation and agents.

Status: disponível

MCP server

A Model Context Protocol server exposing the whole platform to AI agents — buy data, provision lines, manage numbers and Tele Agent from any MCP client. Already powering our ChatGPT app; the same server ships for Claude and other agents.

Status: in progress

Migrate from Twilio in three steps

Bring your Twilio voice/SMS app to esimgomobile without rewriting it: port your numbers, point your webhooks at our compatible endpoints, verify with a test call. A guided toolkit walks the whole move — numbers, messaging and Tele Agent included.

Desenvolvedores 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.

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.

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.

Explainer

How it works, step by step

  1. Pick your plan
    • Choose data for your trip length — 5 GB covers a long weekend, 20 GB a fortnight, 50 GB or Unlimited a month of heavy use.
    • Checkout takes about two minutes through the secure Amazon Pay checkout.
  2. Scan the QR code
    • Your eSIM arrives instantly. Open your phone camera, scan, and the plan installs itself.
    • No store visit, no plastic SIM, no waiting for the post.
  3. Land connected
    • Turn on data roaming for the eSIM line when you land — you're online before baggage claim.
    • The eSIM finds the local partner network automatically.

Explainer

Good to know

  • Charge your phone before long travel days; weak signal areas drain batteries faster.
  • Turn off auto-play on social apps before you fly; it quietly eats roaming data.
  • Download offline maps for your destination — they save data and work in dead zones.
  • Save your eSIM QR code somewhere safe (email it to yourself) in case you switch phones mid-trip.
  • Keep your home SIM active for two-factor codes from your bank; run data on the eSIM line.
  • Buy and install your eSIM before departure — airport Wi-Fi is the worst place to set up connectivity.

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

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.

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