About Us

Stay connected, wherever you go.

Maxesimo was founded in 2026 by travellers who got tired of the same problem, over and over: landing in a new country, phone showing "No Service," and then spending the first hour of the trip standing in an airport SIM shop line instead of already being where you actually wanted to be. Or worse — turning data roaming on "just to check one thing" and finding a €40 charge on the bill a week later.

We built Maxesimo to be the thing we wished existed on those trips: an eSIM that's already installed before you leave home, and just works the second the plane lands.

What we do

Maxesimo provides eSIM data plans covering 189+ destinations worldwide. Whether you're taking a weekend city break, backpacking across continents, or working remotely from a new country every month, we have a plan that fits — from single-country packages to regional bundles covering multiple destinations, all the way to global plans for the frequent flyer.

Beyond the eSIM

Getting connected is only half the story — knowing what to do once you land is the other half. That's why we built our travel guide blog, covering everything you need to know about getting online as a tourist across Europe, Asia, the Middle East, North America, South America, Oceania, and Africa. Each guide breaks down local connectivity options, practical tips, and honest advice on the best way to stay online during your trip — written by people who actually think about this stuff for a living, so you don't have to.

Why eSIM

Our commitment

We work with leading global connectivity infrastructure to make sure your eSIM activates reliably, wherever your trip takes you. Our support team is here to help before, during, and after your trip — because a good connection shouldn't come with bad customer service.
