| 1oT provides global cellular (2G, 3G, 4G, NB-IoT, LTE-M) connectivity to IoT service providers, such as connected bike manufacturers or fleet management companies, by acting as an aggregator of many carrier (telecom) services. Their ideal client is the one who needs to sell to or provide its service with their IoT/M2M devices in differentcountries and don’t want to deal with different carrier integrations, SIM cards, SIM configurations and invoices. 1oT provides its clients with one invoice, one connectivity management platform, and one eSIM/SIM solution, helping clients to drive their business globally with one end-to-end connectivity solution. In 2019, 1oT launched the future technology of SIM cards: eSIM. Technically known as eUICC, eSIM is an unlocked SIM card that enables clients to swap carrier services “over-the-air” securely and at a push of a button. Clients can choose one mobile carrier service today (e.g. telecom I) and decide to swap to another one tomorrow (e.g. telecom II), without changing the physical SIM.In addition to 1oT’s connectivity services, the company has developed an end-to-end IoT connectivity platform, called 1oT Terminal, for clients to control their SIMs & eSIM via a self-service user interface. The platform comes with many value-added services such as API, reporting, diagnostics, and much more. In the future they will add artificial intelligence and machine learning features to the platform that help their customers to get the best possible carrier deals for their eSIM cards.1oT is part of, and co-founded by Mobi Solutions group (http://mobisolutions.com) which among other things was a key developer of the original Skype mobile application, as well as launching the carrier billing service Fortumo, (https://fortumo.com, backed by Intel Capital), and Messente (https://messente.com), the critical business SMS platform service global clients. | Seed / Jun 01, 2016 | ||
