Switch from Phone Call to FaceTime in iOS 12

Switching from a standard cellular phone call to a FaceTime video call is entirely possible in iOS 12, allowing users to transition to video without hanging up first. While Apple updated the calling interface during the iOS 12 release cycle, the operating system still supports a direct handoff from cellular voice to FaceTime video as long as both callers meet the device and network requirements.

How the Transition Works

You can switch seamlessly from an active phone call to a FaceTime video call on iOS 12. When you initiate the switch, your iPhone does not drop the cellular call immediately. Instead, it places the FaceTime request in the background while keeping the cellular audio active. Once the recipient accepts the FaceTime invitation, the video connection engages, and the iPhone automatically terminates the cellular phone call.

Steps to Switch to FaceTime During a Call

1. While on an active cellular call, pull the iPhone away from your face to light up the in-call screen.
2. Tap the FaceTime button located on the call interface. (Note: On iOS 12.0, the FaceTime button was temporarily relocated inside an additional menu, but Apple restored the direct FaceTime button to the main call screen in iOS 12.1.1).
3. Wait for the recipient to accept the video request.
4. Once the video connects, the standard phone call will end automatically.

Requirements for a Seamless Switch

For the switch to work, several conditions must be met:

• Compatible Hardware: Both participants must be using an iPhone, iPad, or iPod touch that supports FaceTime.
• FaceTime Activated: Both users must have FaceTime enabled in Settings > FaceTime.
• Internet Connection: Both devices need an active Wi-Fi or cellular data connection to establish the video stream.
• Carrier Support: If using cellular data for FaceTime, your mobile carrier must support simultaneous voice and data (such as VoLTE), otherwise the cellular call cannot negotiate the data connection required to start FaceTime.
