Wi-Fi is a wireless networking technology that uses radio waves to provide wireless high-speed internet and network connections.
Wi-Fi allows cellular phones and other types of devices to connect to the Internet wirelessly using another Internet source rather than using the cellular data network that is available on the cell phone itself. Wi-Fi service can be provided by a home-based internet service such as DSL and is also provided in many public locations such as restaurants, hotels, business offices, etc. The main benefit of connecting to Wi-Fi instead of using the cellular data network is cost. While connected to Wi-Fi and browsing the internet, streaming music or video, sending emails, etc., the connecting device is not using data from the cellular data plan. The host device is providing the Internet connection and is responsible for data used.
**It’s a good idea to go into your applications and request updates be completed over Wi-Fi signal instead of using the cellular data network. Some updates are quite large and can use a great amount of data.
