Why am I experiencing "digitized sound, audio cuts, or dropped calls" when making a Wi-Fi call on my iPhone over my NocTel Fiber Internet connection?
Depending on your carrier, you may encounter issues where calls made while connected to Wi-Fi experience poor audio or call connection. This occurs when certain carriers default to cellular signal (no matter its strength) even when iPhone Wi-Fi calling is enabled. Because the carrier setting cannot be changed, calls are not actually sent over a Wi-Fi connection when ANY cellular signal is present.
What can I do to improve my call quality?
Ensure Wi-Fi Calling is Enabled
If you have a carrier that supports Wi-Fi calling and has adequate negotiation between cellular and Wi-Fi connections.
Ensure that Wi-Fi Calling is enabled:
- Tap Settings
- Tap Cellular
- Ensure Wi-Fi Calling is "On" under your carrier settings
Disabling Cellular Service
If your Wi-Fi calling is enabled and you are still encountering issues, your carrier may be blocking Wi-Fi calls or prioritizing a weak or poor cellular signal. You can try bypassing a weak cellular signal by turning your cellular service OFF.
To Disable cellular service:
- Turn your phone to airplane mode.
- Reenable your Wi-Fi connection.
- Place a call.
Note!
Please note that if you turn off cellular service and disconnect from or leave your Wi-Fi network's range, your device won't receive or make calls until Cellular service is turned back on.
Note!
Please note that some carriers do not support any Wi-Fi calling: you can check Apple's list here to see if your carrier supports wifi calling: https://support.apple.com/en-us/109526
