With more and more cellphone data getting consumed each day, cell phone providers have network congestion. They can even THROTTLE your device, slowing down its network speed and making it near impossible to make and receive calls.
Luckily, the iPhone has a feature to bypass cell towers and allow you to still speak to your loved ones by accessing WiFi!
To enable this feature, go to SETTINGS -> Cellular -> WiFi Calling. This will allow you to make and receive phone calls anywhere that you can access WiFi.
