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
- Choose data that fits the trip
- Short city break? 5 GB. Two weeks with maps and video calls? 20 GB. Working remotely or hotspotting? 50 GB or Unlimited.
- Every plan shows exactly what you get — no asterisks.
- Install in two minutes
- Buy, scan the QR code, done. The whole thing happens on your phone, wherever you are.
- Install days before you fly or minutes before boarding — your call.
- Switch on and go
- Enable the eSIM line in settings when you arrive. It connects to the fastest local partner network on its own.
- Your home number keeps working for calls and texts on your physical SIM if you keep it active.
Explainer
Good to know
- Save your eSIM QR code somewhere safe (email it to yourself) in case you switch phones mid-trip.
- Set a data alert at 80% so a top-up never surprises you mid-trip.
- Charge your phone before long travel days; weak signal areas drain batteries faster.
- Screenshot your hotel address and booking confirmations — you'll want them with no signal.
- Download offline maps for your destination — they save data and work in dead zones.
- Turn off auto-play on social apps before you fly; it quietly eats roaming data.
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
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.
Roaming bills taught a generation to fear their phones abroad. The eSIM generation simply never learned that fear — data is prepaid, visible and finite.
