Global eSIM
The complete guide.
Best eSIM for global travel
A global eSIM is the plan for round-the-world travellers and digital nomads — one Flysimio line with coverage across 120+ countries on every inhabited continent. A single QR keeps you online whether you're in Tokyo, London, Dubai, São Paulo, or Sydney, with no swapping SIMs and no new plan at each border. Plans are prepaid with no contract and no roaming surprises, and every plan includes free mobile hotspot and a 7-day money-back guarantee. For a multi-continent trip or an open-ended nomad journey, the global bundle means you buy once and stay connected everywhere on the coverage list.
Global plan vs. regional or single-country
The global plan shines when your itinerary spans multiple regions — say Europe, then Asia, then the Americas. For a trip inside one region, a regional bundle (Europe, Asia, North America) is usually better value; for a single country, a dedicated country eSIM is cheapest. But if you're crossing continents, or you simply don't want to think about coverage as you go, the global plan is the simplest possible setup: one eSIM, one install, and it works everywhere in the list without any per-country management.
How to set up your global eSIM
Setup takes about two minutes. Confirm your phone supports eSIM (iPhone XS from 2018 and newer, most Android flagships from 2020), choose your global plan, and pay with card, Apple Pay, or Google Pay — your QR code arrives by email within seconds. Install it on Wi-Fi before you leave via Settings → Cellular → Add eSIM (iPhone) or Network & Internet → SIMs → Add eSIM (Android). It connects automatically in the first country you land in and keeps working as you travel between countries and continents — no reinstalling, no reconfiguring at each border.
How much data do you need for a global trip
Long, multi-country journeys add up, so size generously. For light use — maps, messaging, and email — around 300 MB a day works, but most globe-trotters share more, so budget closer to 700 MB–1 GB a day and lean toward the larger bundles. Digital nomads working on the road, video-calling, and tethering a laptop should choose the biggest plan or an unlimited daily option. Because you can top up at any point in the validity window, a sensible approach is to start with a mid-size plan and add data as your trip unfolds, rather than paying for everything up front.
Hotspot, calls, and staying connected worldwide
Your global eSIM roams across the coverage list, so you stay online as you move between countries and continents — no swapping, no reconnecting. Every plan includes free mobile hotspot, so a laptop, tablet, or travel companion can share your connection anywhere. As a data-only eSIM there's no single phone number, but that rarely matters for a global traveller: WhatsApp, FaceTime, Messenger, and Google Meet handle calls and messages over data worldwide, and your home number stays reachable on your primary SIM. One line, one predictable cost, across the whole trip.
Short trips vs. long-haul global journeys
For a two-or-three-country business swing, a mid-size plan on a shorter validity may be enough. For a multi-month, round-the-world or nomad journey, a large or unlimited plan — topped up as you go — keeps you online across every leg without watching a meter. Because Flysimio plans give you six months to activate, you can buy before you set off and the validity only starts when your eSIM first connects. There's no contract and nothing to cancel — the plan simply ends when it's done, and you can top up or rebuy wherever the road takes you next.
