with other dozens of companies creating smartwatches that have functionalities closer to smartphones including but not limited to mobile apps,
mobile operating system, Bluetooth connectivity, portable media players with FM radio and playback of digital audio and video. Some models are called "WATCH PHONE or VICE VERSA" because they have complete functionality of a typical smartphone using LTE technology such as Apple Watch Series 3.
