Likely causes
- CommonWeak or fluctuating cellular signalChoppy audio is a classic sign of a marginal signal area or moving between towers.
- CommonNetwork congestion during peak hoursHigh call volume in an area can degrade voice call quality.
- PossibleBluetooth connection interferenceOther wireless devices nearby can interfere with a Bluetooth audio connection.
- PossibleWi-Fi Calling switching networks mid-callMoving between Wi-Fi networks or from Wi-Fi to cellular can cause brief choppiness.
- Less commonCarrier-side technical issueA problem on the carrier's network equipment can affect call quality regardless of your phone.
What to do
- Check your signal strength and try moving to an area with more bars or near a window.
- If using Bluetooth, move closer to the connected phone and away from other wireless devices like microwaves or routers.
- Turn off Wi-Fi Calling temporarily and test the call over cellular only, or vice versa.
- End the call and redial to establish a fresh connection.
- Restart the phone to reset its network and Bluetooth connections.
- Check for and install any pending software or carrier settings updates.
- Ask the other caller if the choppiness is on their end, since it could be their connection.
- If the issue happens consistently in the same location, report it to your carrier as a possible coverage gap.
When to call a pro
If choppy audio happens consistently in good-signal areas or on all calls, contact your carrier to check for network issues.
