Over the last several years, upgrades have consistently been made to improve the wireless connection, making the use of wifi for high-quality phone calls and multimedia messages a reality. In the past, phone calls and wireless data connections to the internet were entirely separate services that utilized different antennas to connect on different frequencies. In fact, most fast food restaurants, stores, hotels and coffee shops (among other public areas) offer free wifi hotspots. With the popularity of free public Wi-Fi hotspots, making phone calls from more places may be cheaper than ever before. Since you’re not using a cell tower to place the call, you don’t need a cellular service in order to make a call. Wi-Fi calling relies on a technology called SIP/IMS that sends your phone call through the internet instead of routing to a cell tower. There is no need to log in, and typically no need to use an app to get the job done. Placing a Wi-Fi call it’s just like placing a regular cellphone call. Wi-Fi calling allows you to make high-quality phone calls (and send texts and other media) to people who are connected to a Wi-Fi network. When Wi-Fi calling is turned on or enabled on your mobile device, all of the Wi-Fi networks that the device connects to do the work that would otherwise be handled by cell phone towers. Today, most major cell phone carriers now support Wi-Fi calling, and the option to connect to Wi-Fi now comes standard with the most recent iPhones and Android devices. In the past support for Wi-Fi calling was limited. Generally, your carrier and phone will determine if you are able to place phone calls through Wi-Fi or not.

Wi-Fi calling uses a Wi-Fi connection to make phone calls over the internet, instead of using the network of cell towers owned by wireless carriers and providers.
