What is WiFi calling and how does it work?
WiFi calling is a feature that allows you to make and receive phone calls using a WiFi network instead of a cellular network. This feature is also known as Voice over WiFi (VoWiFi) and it enables you to use your phone’s WiFi connection to make calls, send texts, and access the internet. WiFi calling works by routing your call through the internet using a technology called SIP (Session Initiation Protocol) or VoLTE (Voice over LTE).
When you make a call using WiFi calling, your phone connects to a nearby WiFi network and sends your call to a server, which then routes the call to the recipient’s phone. The quality of the call depends on the strength of your WiFi signal and the speed of your internet connection. WiFi calling is especially useful when you’re in an area with poor cellular coverage, as it allows you to stay connected and make calls even when you don’t have a strong cellular signal.
Do I need a specific phone or plan to use WiFi calling?
To use WiFi calling, you’ll need a phone that supports this feature. Most modern smartphones, including iPhones and Android devices, have WiFi calling capabilities. However, it’s always a good idea to check your phone’s specifications or contact your carrier to confirm whether your phone supports WiFi calling. Additionally, you’ll need a WiFi connection and a data plan that allows for VoWiFi or VoLTE.
Some carriers may also require you to enable WiFi calling on your phone or activate it through their website or mobile app. Furthermore, some plans may have specific requirements or restrictions for using WiFi calling, so it’s essential to review your plan details to ensure you’re eligible for this feature. Keep in mind that WiFi calling may not work in all areas, especially if you’re traveling abroad, so it’s always a good idea to check with your carrier for their WiFi calling policies.
How do I enable WiFi calling on my phone?
Enabling WiFi calling on your phone is usually a straightforward process. On an iPhone, go to Settings > Phone > WiFi Calling, and toggle the switch to enable it.
