Docs: 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.

How it works, step by step
- 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.
- 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.
- 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.

Good to know
- 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.
- Buy and install your eSIM before departure — airport Wi-Fi is the worst place to set up connectivity.
- Turn off auto-play on social apps before you fly; it quietly eats roaming data.
- Hotspot sparingly: one laptop tethered all day can burn through a week of phone data.
- Screenshot your hotel address and booking confirmations — you'll want them with no signal.
These are the details that separate a smooth trip from a stressful one — small, unglamorous, and worth more than any feature list.

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.
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.
