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.

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

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.

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.

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

  • Keep your home SIM active for two-factor codes from your bank; run data on the eSIM line.
  • Download offline maps for your destination — they save data and work in dead zones.
  • Hotspot sparingly: one laptop tethered all day can burn through a week of phone data.
  • Check that your phone is carrier-unlocked before you buy any eSIM — locked phones can't add one.
  • Buy and install your eSIM before departure — airport Wi-Fi is the worst place to set up connectivity.
  • Charge your phone before long travel days; weak signal areas drain batteries faster.

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.
