US Mobile is the next-generation mobile wireless carrier. We are on a mission to help connect the next billion devices from cars and drones to smartphones affordably and without complexity using our proprietary platform. We want to make it possible for people to bring any device online on the two best US 4G LTE & 5G networks as easy as buying something online. Anyone can add a line with the exact plan the device needs, and manage those lines just as easily through an online dashboard, app or using SMS.
