APIリファレンス

Self-serve API keys, a published OpenAPI 3.1 document, JavaScript and Python SDKs, a CLI, com.esimgomobile.* webhooks, a number-porting API, KYC intake and an honest status page. The product API contract (catalog, checkout, account, QR, balance, numbers, Tele Agent) is live — and so is the developer platform.

ドキュメント: 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. 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

  • WhatsApp, iMessage and FaceTime keep your existing number on a data eSIM — no need to tell anyone a new number.
  • Download offline maps for your destination — they save data and work in dead zones.
  • Charge your phone before long travel days; weak signal areas drain batteries faster.
  • Keep your home SIM active for two-factor codes from your bank; run data on the eSIM line.
  • Hotspot sparingly: one laptop tethered all day can burn through a week of phone data.
  • Save your eSIM QR code somewhere safe (email it to yourself) in case you switch phones mid-trip.

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.

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.

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