Your call quality will depend on the strength and quality of your internet connection and WiFi signal.
If you’re connected to a strong Wi-Fi signal supported by a good internet connection, you shouldn’t notice a difference in call quality. We recommend a WiFi connection speed of at least 1Mbps to use Wi-Fi Calling.
If the call quality is consistently poor, the WiFi signal or internet connection may not have enough bandwidth to support WiFi Calling. This often happens when a lot of people are using the WiFi or internet connection at the same time, or are using it for bandwidth-intensive tasks like streaming movies.
You should also check if you’re connected to WiFi, as not all WiFi networks will keep you logged in indefinitely.
If your call isn’t connected by the Vodafone Broadband network, we can’t guarantee the call quality. If you’re still having issues, you can get support
