Why does my call sound broken up? Why am I experiencing poor quality calling regular or mobile phone numbers?

In general, "choppy" calls or poor quality are the result of latency or packet loss in your mobile network. In other words, your Internet connection may not be fast enough to send and receive voice data, resulting in lost information.

This may occur when connection speeds are compromised by mobile network problems, network congestion, or heavy bandwidth usage such as online gaming or the upload/download of files.

• Check a few web sites you commonly view and see if they are performing slower than usual. If this is the case, it is probable that your mobile network is experiencing a problem.

Try the following solutions on your smartphone to resolve the quality issues.

1.) Check if your Mobile VoIP app supports G729 compressed codec and is chosen as default or preferred codec. G729 codec works better if you have low speed Internet connection.

2.) Check if your Mobile VoIP app supports iLBC compressed codec and is chosen as default or preferred codec. You can find codec options usually in advanced configuration of your Mobile VoIP app.

3.) Try using your smartphone VoIP service with a Wi-Fi Internet connection and see if the quality improves. If you experience better quality, this would confirm that the issue is due to your Internet connection speed.
