  • 1 mil (e)SIMs managed on 1oT Terminal
  • 500k (e)SIMs sold worldwide
  • #1 choice by eScooter industry

Founded in 2016, but dating back to 2001

We are co-founded by Mobi Solutions Group, which among other things, was a key developer of the original Skype mobile application through Mobi Lab, has launched the carrier billing service Fortumo, which is backed by Intel Capital and serving customers like Amazon & Google Play, and an SMS service Messente.

We know what we are doing as we have built value-added services on top of carriers for almost two decades (Fortumo, Messente) and are developing our connectivity management platform, called 1oT Terminal, 100% in-house.

We are self-sustainable and do not live on investor's money. However, 1oT can be characterised by a startup mindset and an ambition to disrupt the global IoT connectivity sphere.

We are acknowledged worldwide. 1oT has enabled many top eScooter sharing companies to scale throughout Europe and the USA, fleet management companies to expand in Africa and Asia, and smart city solution providers to set up their services in Europe.
