Mobile, the way we always wanted it

Simsalasim is an AI-native software company. And the reason your phone plan finally works everywhere. Mobile was built around national borders for decades.

We did not want to make that cheaper. We wanted to make it different.

Our founders have spent decades in telecom and tech. Again and again they ran into contracts that tie you down and fees nobody can explain. So they started over on today’s technology and built Simsalasim: one plan without fine print, cancellable every month.
