Recently my seniors complex had all of their electrical conduits put in the roof. Several of these conduits are run in the roof over my apartment. Since then my cell phone reception has been spotty. By this I mean that when I am speaking to my daughter who lives 20 miles away, Her voice fades out or vibrates so badly I cannot understand her. There has been no problem with messaging just phone calls. This is becoming very annoying. Is this the reason for my problem and is there any solution that you can give me. Thank you.
