Fix 7. Verify your Internet connection

A stable internet connection is crucial for the smooth operation of FaceTime, especially for video calls. If you're experiencing lag or other issues during calls, it could be due to a poor network connection.

To troubleshoot this, navigate to your device's Settings to assess your internet connectivity. If you're on a Wi-Fi network, try turning the Wi-Fi off and then on again.

You can also try forgetting the network by selecting it, tapping Forget This Network, and then rejoining it or connecting to a different network.

Ensure that you're connected to a reliable Wi-Fi network. If Wi-Fi isn't available or is unstable, switch to your cellular data connection as an alternative.

Part 3. FAQs about FaceTime lagging

Q1: Is there a minimum internet speed required for FaceTime to work smoothly?

Apple doesn't specify a minimum speed, but a good rule of thumb is to have at least 1 Mbps for a reliable FaceTime call. Higher speeds will generally improve the quality and reduce lag.

Q2: Can the distance between callers affect FaceTime lag?

The physical distance between callers can affect latency, as data has to travel longer distances. However, this is usually not noticeable unless there is an issue with the network routing.

Q3: Will FaceTime lag less if I reduce the video quality?

FaceTime automatically adjusts video quality based on the connection speed. Manually reducing video quality is not an option, but a stronger connection will naturally improve video quality with less lag.


FaceTime can help us chat with friends face to face via a smartphone. Lagging during FaceTime calls can be frustrating as it affects the quality of the conversation and may lead to misunderstandings or a less enjoyable user experience.
