Dual SIM, zero hassle
Keep your home number active alongside your esimgomobile line. Switch data between them in your phone's settings.
Top up anytime
Running low? Add data from your dashboard or automatically — your line never dies mid-trip.

Carrier-locked phones may need unlocking first. If your exact model isn't listed, check your manufacturer's specs for eSIM support — or use a virtual number, which works on any device.

esimgomobile eSIM: 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.

Good to know
- If a page won't load, toggle airplane mode for ten seconds — it forces a fresh network attach.
- 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.
- Turn off auto-play on social apps before you fly; it quietly eats roaming data.
- WhatsApp, iMessage and FaceTime keep your existing number on a data eSIM — no need to tell anyone a new number.
- Check that your phone is carrier-unlocked before you buy any eSIM — locked phones can't add one.
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.
