Unlimited Data. In Any Country.

What is an eSIM?

An eSIM is a tiny chip inside your phone that does the same job as the little plastic SIM card you might be used to.

An eSIM lets your phone connect to a mobile network so you can use data — Only you don’t have to take it out or put it in. It's already there, and you just activate it digitally.

Why Our eSIMs Are The Best?

Well, because all our eSIMs have unlimited data.

Totally Untethered exists for people who crave freedom — the backpackers, digital nomads, solo adventurers, and anyone tired of being told “You’re out of data” while on the move.

Our eSIMs are instant. No contracts, no roaming surprises, and no physical SIMs to fumble with. Just activate in seconds, and go — in over 200 countries.

The world isn’t meant to be traveled in slow motion. Your eSIM shouldn’t slow you down either.
