| Verizon | 8400 Byron Center Ave SW | Poor signal and lots of dropped calls.  It's gotten to the point that I have to leave my house to make a call.  Or sit by a window to attempt to make a call. | 2014 |

| Verizon | 1635 Sentinal St SW | 99% of calls drop, 80% of calls never ring, never say missed call.  Text messages arrive about 30 to 45 minutes after they're sent. | 2014 |

| Verizon | 545 Porritt Dr | Very poor service, usually 1 bar 3G or 1x.  In an attempt at a 5 minute conversation only the 5th word is normally heard and drops calls all the time.  Data rate is very erratic and very undependable. | 2015 |

| Verizon | 13815 36th St SE | Last several months dropping calls, no signal, or lost duplex connection (I hear caller, but not vice-versa) during call. | 2019 |
