How to reduce echo?
Echo is the result of transmission speed mismatch (ie outgoing channel is quicker than the incoming channel) and volume differences. You’ll experience some echo every-now-and-then and that’s quite normal. If you get echo all the time, check if the volume of your phone is too loud. Some phones let you adjust the incoming volume. If possible also ask the person you’re calling to reduce the volume a little bit and see if it makes a difference.
