What is a Global eSIM?

A Global eSIM is a digital SIM that gives you mobile data in 150+ countries on a single plan. You scan a QR code sent to your email — no physical SIM, no airport SIM kiosks, no roaming bills.

How many countries does the Onetel Global eSIM cover?

The Onetel Global eSIM covers 150+ countries across every continent, including Europe, Asia, the Americas, Africa, the Middle East, and Oceania.

Can I use a Global eSIM on a multi-country trip?

Yes — that's exactly what it's designed for. One Global eSIM plan works seamlessly as you move between countries. Your shared data balance follows you without any extra steps.

What is the difference between Unlimited and Fixed GB Global eSIM plans?

Unlimited plans give you uncapped data (subject to a fair-use policy at very high usage). Fixed GB plans (1GB, 3GB, 5GB, 10GB) are one-time data allowances — ideal if you know roughly how much data you'll need.

How do I activate a Global eSIM?

After purchase you receive a QR code by email. Go to Settings → Cellular → Add eSIM on your phone and scan the code. It takes under 2 minutes and you can do it before you leave home.

Is there a refund policy for Global eSIM plans?

Yes. If your eSIM has not been activated, you can request a full refund within 30 days of purchase. Contact Onetel support and we'll process it promptly.

Questions We Get Often

What people ask about the Global eSIM, answered

One profile, 150+ countries. A Global eSIM is a single digital SIM profile you install from one QR code before you leave home. After that it works country to country and continent to continent on its own. No hunting for a SIM shop on arrival. No roaming charges landing on your phone bill.

The list runs past 150 countries: all of Europe, North America, most of Asia-Pacific, the Middle East, Latin America and the major African destinations. It shifts slightly from plan to plan, so each plan\'s detail page carries its own exact country list. Check yours against your route before paying.

Yes. That is the whole point. One data allowance covers every country included in the plan. At the border the eSIM picks up a local carrier by itself — nothing to change in settings, no reboot, and nothing extra to pay.

Fixed GB plans hand you a set bucket — 1 GB, 3 GB, 5 GB and so on — at full speed for the entire validity period. Unlimited plans are uncapped instead. Most countries stay on full 4G LTE the whole time; in a small number of markets speeds can be soft-capped once you pass a generous fair-use threshold, usually 1–3 GB per day.

First use. The countdown begins the first time your eSIM connects to a network in a covered country. Buy and install weeks ahead if that suits you; no days get "burned" sitting there. Nothing ticks down until you are actually travelling.

The floor is 4G LTE in every covered country. Where our carrier partners have built 5G and your device supports it, you get 5G — today that covers most of Western Europe, the US, Japan, South Korea, Australia and the UAE. What you actually see depends on where you are and how busy the network is.

Yes, on most Global plans. Share the connection with a laptop or tablet the way you would at home. One caveat: on Unlimited plans, hotspot traffic can fall under its own fair-use speed policy. If you work off a tethered laptop, read the plan details first.

Nothing happens — the eSIM stays offline there. Your physical SIM takes over, if it is still in the phone. For remote places the Global plans miss, there are single-country and regional plans you can add to the same eSIM device.

Yes. Nearly every eSIM-capable phone holds several profiles at once. Install a Global plan beside your existing regional ones and pick whichever you want from the cellular settings menu.

No. Global plans carry data and nothing else. Run calls and messages over that data with WhatsApp, FaceTime, Skype or iMessage. Your physical SIM stays active, so ordinary calls and texts still reach your home number.

Stack plans. Start on a 30-day Global plan and renew it as the trip runs on, or add regional plans for the places you will sit still longest. Send your itinerary to support and we will work out the cheapest combination with you rather than guessing.

An eSIM is a programmable chip soldered inside the device — embedded SIM. Nothing goes into a tray. You scan a QR code and the carrier profile downloads over the air. So: activation in seconds, no tiny plastic card to lose in a hotel room, and several plans held at the same time on a dual-SIM device.

If the phone launched after 2018, it probably does: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later, plus many other Android flagships. It has to be carrier-unlocked. Quick test: open Settings → Mobile / Cellular and look for "Add eSIM" or "Add Data Plan". If it is there, you\'re good to go.

Settings → Mobile / Cellular → Add Plan, then scan the QR code from your email. Under 2 minutes, start to finish. You need Wi-Fi or an existing data connection while you do it, which is why home beats the airport.

Yes. On a dual-SIM phone the two lines run independently. Point data at the eSIM and leave calls and texts on the physical SIM. Your home number keeps ringing while the data comes from the cheap side.

Yes — carrier-unlocked, no exceptions. Phones bought straight from the manufacturer (Apple Store, Google Store, Samsung.com) usually are. One that came from a carrier may still be locked, so ask your home carrier before you buy.

No. For security, each eSIM QR code is single-use by design, and after the scan the profile is bound to that device. If you have to install again — say after a factory reset — ask support and we\'ll issue a fresh QR code.

Same network, same speed — the chip changes nothing. Plans generally run 4G LTE worldwide, with 5G in countries where our carrier partners have the infrastructure and on devices that support it.

Onetel eSIM plans carry data only. Calls and messages go over WhatsApp, FaceTime, iMessage, Skype or any VoIP app. Traditional mobile calls on your home number keep working through your physical SIM.

The profile stays on the device. It just stops routing data. Buy and activate a new plan whenever the next trip comes up — no rescanning, no reinstalling. Treat the eSIM profile as a permanent slot you refill as needed.

Yes. Most eSIM-capable devices keep several profiles on file and you flip between them in settings. Hold a Global plan and a country-specific plan side by side, then switch on whichever fits where you are.

Onetel is a global eSIM marketplace. We pull travel data plans from a range of carrier partners and put the lowest price for each destination in front of you. QR codes arrive instantly, prices are stated plainly, and support is answered by people — no hidden fees, no lock-in contracts.

From wholesale eSIM providers and regional carriers around the world. Rather than listing everything, we keep a curated selection of the best-value plans per destination. Enter your country, duration and data amount, and the system puts the cheapest option on top.

Yes. TLS encryption covers every transaction. Pay with Visa, Mastercard, American Express, PayPal, Apple Pay or Google Pay. Card details go straight to our payment provider and are never stored on Onetel servers.

Instantly — usually within 10 seconds of the payment clearing. The QR code arrives by email and also sits in your account dashboard. Nothing in the inbox after that? Look in spam, or just log in and grab it there.

Two cases get a full refund: the eSIM failed to activate, or you have not used any data. Claim within 30 days of purchase and give support your order number. Once a plan has been activated and data consumed, it is non-refundable. Most requests are settled within one business day.

Yes. Raise the quantity at checkout and every person gets their own unique QR code, all sent to the same email address. Group or company trips of 10+ people: ask our team for a bulk pricing quote.

No. Onetel travel eSIMs are one-time purchases. No subscriptions, no recurring billing, nothing turning up on your card later. You choose what to buy and when.

Live chat sits in the bottom-right corner of every page, and email works too. Both are staffed 24/7. For activation problems use chat — replies typically come within 2 minutes. Email answers land within a few hours.

Yes. A detailed tax invoice reaches your email automatically after purchase: your name, the plan details, the amount paid. That covers what an expense claim or VAT reclaim asks for.

One is being built. Until then, promotional codes and loyalty rewards show up in your account dashboard. Refer a friend and you both benefit — the referral section of your account has the details.
