About Us
Stay connected, wherever you go.
Maxesimo was founded in 2026 by travellers who kept running into the same problem. You land in a new country, your phone says "No Service", and the first hour of your trip disappears in an airport SIM shop queue instead of being where you actually wanted to be. Or worse, you turn on data roaming "just to check one thing" and find a €40 charge on your bill a week later.
We built Maxesimo to be the thing we wished we had on those trips: an eSIM that is already installed before you leave home and simply works the moment the plane lands.
What We Do
Maxesimo provides eSIM data plans covering 189+ destinations worldwide. Whether you are on a weekend city break, backpacking across continents or working remotely from a new country every month, there is a plan that fits, from single-country packages and regional bundles to global plans for frequent flyers.
Beyond the eSIM
We don't just sell travel eSIMs. We use them, test them and build our guides around the questions travellers actually ask. Will it work when I land? How much data will I need? How do I get online quickly? We want Maxesimo to be useful before, during and after your trip, not only at checkout.
Getting connected is only half the story; knowing what to do once you land is the other half. That's why we write our travel guides, covering mobile data and eSIM abroad, getting around by public transport, duty-free rules and local tips, from Europe to Asia, with new destinations added regularly. Each guide is written from real trips, by travellers who have been there and know what actually matters when you're trying to stay connected abroad.
Why eSIM
No physical SIM
Nothing to lose, swap or damage. Everything is digital.
Instant activation
Install before you leave home, activate the moment you land.
Keep your number
Stay reachable on your home SIM while using data on your eSIM.
Minutes, not hours
No queues, no shops, no waiting for your data plan.
Our Commitment
We work with leading global connectivity partners to make sure your eSIM activates reliably, wherever your trip takes you. Our support team is here 24/7, before, during and after your trip, because a good connection shouldn't come with bad customer service. If you get stuck, our step-by-step setup guide and Help Center cover the most common questions.
