It is important to test the connection quality of the Internet service that your mobile device uses. This can help you determine how well it will work for videoconferencing.
Use a third-party bandwidth testing app to verify that your network connection meets the minimum requirements (5 Mbps download speed; 0.77 upload speed). For example, speedsmart.net, fast.com, or speedtest.net.
If the test results are not within the recommended range, you might have connection issues. These issues can cause your video to flicker or freeze and can produce clicks, pauses or other undesired effects in the sound quality.
If you are unfamiliar with your network and its bandwidth capacity, contact your Internet Service Provider (ISP) or network support staff for information or to investigate the quality of your network connection.
