| AT&T | 5443 Twilight Common | Poor cellular coverage, Dropped calls, Poor cellular reception | 2015 |
| Verizon | 5585 Portsmouth Ave | Almost no signal, 1 bar at most | 2019 |
| AT&T | 260 A N Mathilda Ave | We moved 1000 steps away from our previous location, and the bars went from 2 to 1. Reception went from tolerably bad to untolerably worse. Called the ATT technical support, and they validated the presence of many microcells in this area (which is an indication of folks having the issue). Apparently, by beginning of next year, the 2G towers will be decommissioned and will be covered by 3G/4G instead. Starting at Poinciana and Lawrence intersection to Monroe and Lawrence intersection - the signal just drops (it is a deadzone). | 2019 |
| Sprint | 824 Blair Ave | Very splotchy service while on a call | 2019 |
