Who I have the same questioned this topic

I have both a Verizon work phone (iPhone 7+) and a personal phone (12 Pro) and have an area of poor coverage that I drive through daily.  The area is suburban in nature and is frequently traveled, not to mention, just off the Florida Turnpike.  There is no reason for poor service in this area.  We have lived in the area for 2 years and it hasn't improved.  5G was just added, but it didn't help.  How can I report this area, or how would l be able to upload a map to indicate where it is.  

Calls drop or so bad I just get off the phone and data is unusable.  My wife and daughter are having the same experience, so it's not just me.
