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.

Frequently Asked Questions

All you need to know about your Global eSIM

A Global eSIM is one digital profile that works in 150+ countries. Install the QR code before your trip and your data plan moves with you across borders — no separate SIMs, no roaming surprises.

Global plans stretch across 150+ countries, covering all of Europe, North America, most of Asia-Pacific, the Middle East, Latin America, and major African destinations. Coverage varies slightly between plans. Each plan's detail page lists the exact countries — check your specific stops before buying.

Yes — that's the point. Your data allowance is shared across every covered country in the plan. Cross a border and the eSIM connects automatically to the local carrier, with no settings change, no reboot, and no extra cost.

Unlimited plans give you uncapped data. In most countries, full 4G LTE speeds apply for the whole plan; in a few markets, speeds may be soft-capped after a generous fair-use threshold (typically 1–3 GB per day). Fixed GB plans give you a precise data bucket — 1 GB, 3 GB, 5 GB, etc. — at full speed for the entire validity period.

Validity starts on first use — specifically, the first time your eSIM connects to a network in a covered country. You can buy and install the eSIM weeks ahead without "burning" any days. The plan only counts down once you're actually travelling.

4G LTE is the baseline in all covered countries. 5G is available on compatible devices where our carrier partners have deployed 5G networks — currently including most of Western Europe, the US, Japan, South Korea, Australia, and the UAE. Actual speeds vary by location and network congestion.

Yes, most Global plans support personal hotspot, so you can share your data with a laptop or tablet. On Unlimited plans, hotspot traffic may be throttled under a separate fair-use policy. If hotspot is essential, check the plan details before you buy.

The eSIM won't connect in uncovered countries. Your physical SIM, if still inserted, takes over. For destinations outside Global coverage, we also offer single-country and regional plans that work on the same eSIM device.

Yes. Most eSIM-capable phones store multiple eSIM profiles. Install a Global plan alongside your existing regional profiles and switch between them from your phone's cellular settings whenever you need.

Global plans are data-only. For voice calls and messages, use apps like WhatsApp, FaceTime, Skype, or iMessage over your data connection. Your physical SIM stays active for traditional calls and texts on your home number.

For long multi-continent trips, stack plans strategically: start with a 30-day Global plan and renew as needed, or pair it with regional plans for areas you'll spend the most time in. Contact our support team for a personalised recommendation — we're happy to map out the most cost-effective solution for your itinerary.

An eSIM is a programmable chip built into your phone. There's no plastic card to swap — you download a carrier profile by scanning a QR code. That means instant activation, nothing small to lose, and room for several plans at once on a dual-SIM device.

Most phones launched after 2018 accept eSIM: iPhone XS and later, Google Pixel 3 and later, Samsung Galaxy S20 and later, plus many other Android flagships. The device must be carrier-unlocked. Check Settings → Mobile / Cellular — if you see "Add eSIM" or "Add Data Plan", you're set.

Open Settings → Mobile / Cellular → Add Plan, then scan the QR code we send by email. It takes under 2 minutes and needs Wi-Fi or an existing data connection. Best done at home before you travel — no fuss at the airport.

Yes. On dual-SIM phones, the eSIM and physical SIM work independently. Use the eSIM for data, keep the physical SIM for calls and texts — you stay reachable on your home number while using affordable eSIM data abroad.

Yes — the phone must be carrier-unlocked. Devices bought directly from Apple Store, Google Store, or Samsung.com are usually unlocked. If you bought from a carrier, you may need to ask them to unlock it first.

Each eSIM QR code is single-use by design, for security. Once scanned, the profile is locked to that device. Need a fresh one after a factory reset? Contact support and we'll issue a new QR code.

An eSIM connects to the same mobile networks a physical SIM uses, so you get identical data speeds. Most plans provide 4G LTE coverage globally; 5G is available when your device supports it and our carrier partners have 5G equipment in the country you're visiting.

Onetel eSIM plans are data-only. For calls and messages, use WhatsApp, FaceTime, iMessage, Skype, or any VoIP app. Your physical SIM still handles traditional mobile calls to your home number.

Your eSIM profile stays on your device — it just stops routing data. You can buy and activate a new plan anytime without rescanning or reinstalling. Think of the profile as a permanent slot you top up when needed.

Yes. Most eSIM-capable devices hold multiple profiles, and you switch between them in settings. Install a Global plan and a country-specific plan at the same time, then activate whichever fits your location better.

Onetel pulls together prepaid travel data from multiple carrier partners, so you can compare and pick the right plan for any destination without hopping between sites. We keep delivery instant, pricing transparent, and support human — no hidden charges, no contracts.

We work with wholesale eSIM suppliers and regional carriers around the world, then pick the best-value options for each destination. Our system automatically shows the cheapest plan for your chosen country, length of stay, and data allowance.

Yes. Every transaction is encrypted with TLS. We accept Visa, Mastercard, American Express, PayPal, Apple Pay, and Google Pay. Your card details are handled by our payment provider and never stored on Onetel servers.

QR codes arrive instantly — usually within 10 seconds of payment. They are sent by email and also saved in your account dashboard. If the email does not turn up, check your spam folder or log into your account.

You can get a full refund within 30 days as long as the QR code has not been scanned and the eSIM has not been installed or activated. Once installed or activated, the eSIM is non-refundable even if you used no data. Contact support with your order number.

Yes. Just bump up the quantity at checkout — each person gets their own unique QR code sent to the same email. For groups or corporate trips (10+), get in touch for a bulk quote.

No. Onetel travel eSIMs are one-off buys — no subscriptions, no recurring billing, no surprises. You pick what to buy and when.

Support is on 24/7 via live chat (bottom-right of every page) and email. For activation problems, live chat is quickest — we usually reply within 2 minutes. Email gets back to you within a few hours.

Yes. A detailed tax invoice goes to your email automatically after purchase — it includes your name, plan details, and amount paid, so you have everything for an expense or VAT claim.
