What Are Smart Watches?
A Smartwatch Is a wearable computer in the form of a watch; modern smartwatches provide a local touchscreen interface for daily use, while an associated smartphone app provides management and telemetry, such as long-term biomonitoring. While early models could perform basic tasks, such as calculations, digital time telling, translations, and game-playing, smartwatches released since 2015 have more general functionality closer to smartphones, including mobile apps, a mobile operating system, and WiFi/Bluetooth connectivity. Some smartwatches function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth headset. Some models, called watch phones (or phone watches), have mobile cellular functionality such as making telephone calls.
Other smartwatches are standalone devices with a specific purpose. For instance, some smartwatches collect data about the wearer’s health, monitoring the wearer’s heart rate, for instance. Others provide Global Positioning System (GPS) data, providing the wearer with walking or driving directions.

What Do Smart Watches Do?
Like smartphones, they use touchscreens, offer apps, and often record your heart rate and other vital signs. The Apple Watch and Wear (formerly Android Wear) models prompted more consumers to appreciate the usefulness of wearing a mini computer on their wrists.
Does a Smart Watch Need A SIM Card?
Most smartwatches don’t require a SIM card because they connect to your phone, usually via Bluetooth, and use it to access the mobile network. However, if you’re looking to equip your child with a smartwatch that supports GPS, so you can use it as a location tracker, then you’ll want a SIM card.
Can Smart Watch Work Without A Phone?
Without the need for a phone, most new smartwatches come with their own GPS chips and can still display a good amount of fitness tracking data, and they can store media like offline Spotify playlists and other audio that can be listened to via Bluetooth headphones.
