Docs: 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.
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.
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
- 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.
- 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.
- 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.

Good to know
- Turn off auto-play on social apps before you fly; it quietly eats roaming data.
- Check that your phone is carrier-unlocked before you buy any eSIM — locked phones can't add one.
- Keep your home SIM active for two-factor codes from your bank; run data on the eSIM line.
- 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.
- WhatsApp, iMessage and FaceTime keep your existing number on a data eSIM — no need to tell anyone a new number.
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
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.
