WiFi Calling can be a handy feature when your iPhone struggles with weak cellular signals, especially indoors or in remote areas. While it's built into most modern iPhones, many users don't know how to turn it on or use it properly. If you've ever experienced dropped calls or poor call quality, this feature might be the solution. In this guide, we'll show you how to enable and use WiFi Calling on your iPhone, along with a few simple tips to fix common issues.

WiFi Calling is a feature that allows your iPhone to make and receive phone calls over a WiFi network instead of relying on a cellular signal. This is especially useful when you're in places with weak or no signal, such as inside buildings, basements, or remote areas.
Instead of connecting to your carrier's cellular towers, your iPhone routes calls through a stable WiFi connection. From a user's perspective, everything works the same as a regular call - you can dial numbers, receive calls, and even access voicemail as usual (Voicemail Not Working on iPhone?).
WiFi Calling is built into most modern iPhones and works automatically once enabled. When your cellular signal is poor, your device will switch to WiFi Calling to maintain better call quality and connection stability.

WiFi Calling on iPhone is often free, but it depends on your carrier and the type of call you make.
In most cases, calls made over WiFi to numbers within your country are treated the same as regular calls and are included in your existing plan. This means you usually won't be charged extra for using WiFi Calling domestically.
However, international calls may still incur charges based on your carrier's rates, even if the call is made over WiFi. It's important to check your carrier's policy to understand any potential fees.
Also, while WiFi Calling itself doesn't use your cellular minutes in some cases, it does rely on an internet connection. If you're using a limited WiFi network or hotspot, data usage may apply.
To avoid unexpected charges, it's always a good idea to confirm the details with your carrier before using WiFi Calling frequently.
