In 3GPP standards from 3G onwards, all mobile devices that can connect to cellular networks, including smartphones, data cards, hotspots, tablets, and more recently connected devices like cars and fridges, are referred to as User Equipment (UE). UE is an evolution from the term Mobile Station used in earlier 1G and 2G standards, as devices have advanced from simple "feature phones" to include both phone and computing functionality as well as the ability to access the internet from mobile data connections.
