Not really, since the SCOTUS has long held that any conversation that uses a cellphone has no expectation of privacy. They have really beaten the issue to death, that any and every form of electronic communication can be monitored by the government at whim.
In most cases, even face to face communication has little protection. If the government installs listening devices, it is a crime to tamper with them, interfere with them, or even point them out to others.
That presumes you knew they were government listening devices. To me they might look like buttons or pieces of that old router I took apart... Sorry, just thought it was electronic debris from our modern lifestyle, cat toys, etc. ...they're somewhere at the local dump by now... Now, prove I knew they were government listening devices that I shouldn't have tampered with.
