Gonna rant, cause I know how much John loves it.
Okay, so if someone calls you and you tell them that you can't hear them because they are breaking up STOP TALKING!! Say you'll call right back, find a spot where your reception is better and call. Just because you keep trying or saying, can you hear me now because you moved two feet, doesn't automatically fix the problem. A network of people aren't going to come up behind you and magically make everything clearer.
