| Sprint | 15224 Aqueduct Ln | Poor data quality | 2014 |
| Verizon | 9483 Haven Ave | Weak 4G signal | 2016 |
| AT&T | 9400 Fairway View Pl | I live close to 6th street. Service drops repeatedly, no bars inside bldg, 1, maybe 2 bars at most outside. Had to get a landline (ooma) to make calls. | 2019 |
| AT&T | 150 E Holt Blvd | Almost ALL DAY reception is zero to one bar. Hence, data is incredibly slow, calls are often scrambled and dropped, sent texts are often returned. It's been like this for YEARS and I still have to rely on landlines to ensure a successful phone call. I work and live here and service is TERRIBLE! It's like I live in the boonies. | 2019 |
