LINE voice and video calls are made over an internet connection, so make sure the connection you're using is stable.
If a call has no sound or is broken up, it may be because:
• You're connected to a Wi-Fi network being used by many people.
Note:
- We recommend using a 3G or 4G network.
- If you use a 3G or 4G network, you will be charged for the data used during calls.
• The signal is weak.
• You're updating apps or uploading/downloading files while on a call.
• Some router settings are affecting your connection.
If you've checked everything above but are still experiencing issues, try the following troubleshooting tips, and have your friend do the same.
• Update LINE to the latest version
