1oT is aggregating many telecoms around the world into one eSIM and connectivity management platform to provide global connectivity to IoT devices. Our two software elements, the eSIM infrastructure and connectivity management platform, have been developed in-house and have stood out in the market. With the certified eSIM infrastructure (1oT eSIM Core), our customers can swap telecoms whenever they wish, and with the connectivity management platform (1oT Terminal), they can control and manage connectivity on a self-service basis either through our UI or APIs.

Our 2G, 3G, 4G, NB-IoT, and LTE-M connectivity service is used by 4 million IoT devices in 173 countries. But we haven’t stopped there. We have been building our own packet gateway-a secure interface between mobile networks and external packet data networks, including the Internet, private corporate networks, and other IP-based services. You'll be working on the core of 1oT’s connectivity infrastructure. Your job is to ensure seamless, lightning-fast data flow for IoT devices worldwide by building and optimizing our in-house packet router.
