Yes, however, a cell phone should only be used as a last resort. The cell phone connection will be dependent on the signal strength and network. We cannot guarantee a steady cell phone connection. You'll want to make sure that you are in a location that will give you the best signal strength. Also, it's best to not move around while connected as this can sometimes cause a weakness in the signal strength and then cause audio issues or a dropped connection.
If you are experiencing more than usual issues with your connection, you'll need to contact your mobile service provider to check for possible network issues.
