FAQ

Frequently asked.

Is esimgomobile live?
Yes — plans are live with real checkout, your dashboard activates after your first purchase, and a human replies to every message.
How do I install an esimgomobile eSIM?
After purchase you get a QR code instantly. iPhone: Settings → Cellular → Add eSIM → scan. Android: Settings → Network → SIMs → Add eSIM → scan. Your dashboard can re-issue the code anytime.
Why do you need my ID?
Real phone numbers are regulated. Carriers require identity verification before issuing numbers in most countries — we collect it once at signup and handle the compliance.
What is Tele Agent?
Our AI receptionist: it answers your business calls 24/7, books appointments into your calendar, takes messages and sends you a summary after every call. Details on the Tele Agent page.
Can AI agents use esimgomobile?
Yes — that's a core use case. Agents get API keys and our MCP server to buy data, provision eSIMs, rent numbers and manage Tele Agent programmatically. See Developers.
How do I request a support call?
Use the request-a-call form on this page. We queue every request and call you back in your chosen time window.
Do you offer phone support?
Yes — request a callback with the form above, or reach us any time by email. Tele Agent is our AI receptionist for your business lines, not our support line.
What are your support hours?
Our support team is available during business hours, and we monitor email every day — a human replies to every message.
Can I get help in my language?
Yes — we support the same six languages as this site: English, Spanish, French, German, Portuguese and Japanese.
How do I contact support?
Email support@esimgomobile.com — we reply to every message.

Support & Contact: 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.

Explainer

How it works, step by step

  1. 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.
  2. 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.
  3. 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.
  • 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.
  • Turn off auto-play on social apps before you fly; it quietly eats roaming data.
  • Charge your phone before long travel days; weak signal areas drain batteries faster.

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

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.

Roaming bills taught a generation to fear their phones abroad. The eSIM generation simply never learned that fear — data is prepaid, visible and finite.
