Live now

API-first, down to the 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.

Live today

The developer platform is already open.

No sales call, no human-gated first project: sign in and mint your own API keys. The product endpoints (catalog, checkout, numbers, Tele Agent) are live — everything below works right now.

Self-serve API keys

Sign in with Firebase and mint esk_live_… keys instantly — scoped to a project (production, test, experiment), hash-stored, revocable in one call.

# mint a key
curl -X POST \
  https://api.esimgomobile.com/api/v1/keys \
  -H "Authorization: Bearer $FIREBASE_ID_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name":"ci","project":"test"}'

Webhooks: com.esimgomobile.*

HTTPS endpoints, per-endpoint HMAC-SHA256 signatures (Stripe-style t=…,v1=…), at-least-once delivery with backoff, dead-lettering and replay. Billing, number provisioning, porting, calls, SMS, key and KYC events.

Number porting API

draft → information_required → pending → completed. The API tells you exactly which fields each country needs before you submit — submission is fail-closed until carrier onboarding completes.

KYC intake

Collect the identity documents carriers require per country. Verification stays honestly pending_verification until a verification vendor is configured — never a fake "verified".

Honest status page

Component states derived live from service configuration — never fabricated uptime percentages.

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: live

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: live

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.

esimgomobile Developers: the full picture

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 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.

Explainer

How it works, step by step

  1. Buy before you fly
    • Order from home, the hotel, or the departure lounge — delivery is instant and digital.
    • No shipping, no pickup counters, no airport SIM queues.
  2. Add the eSIM
    • One QR scan adds the plan to your phone. iPhone and Android both walk you through it in under a minute.
    • You can install now and activate later — the plan starts when you choose.
  3. Stay online abroad
    • Data, maps, translation and messaging work the moment you land.
    • Running low? Top up in one tap from your dashboard — no new QR code needed.

Explainer

Good to know

  • If a page won't load, toggle airplane mode for ten seconds — it forces a fresh network attach.
  • Save your eSIM QR code somewhere safe (email it to yourself) in case you switch phones mid-trip.
  • Buy and install your eSIM before departure — airport Wi-Fi is the worst place to set up connectivity.
  • Download offline maps for your destination — they save data and work in dead zones.
  • Set a data alert at 80% so a top-up never surprises you mid-trip.
  • 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

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.
