| Verizon | CA-94 | Verizon wireless is nearly non-existent in this location. Service fades in and out with there being more times with no service than service. No such thing as 4G at this location and if you find the right location to stand in, you might be lucky enough to get a bar or two of 3G. Verizon really needs to put a booster in the area. | 2019 |
| Verizon | 531 Alta Rd | Very bad signal, keeps logging into Mexican service. inside office if it wasn't for WiFi calling I would never be able to make a phone call, and even then the quality is really bad. | 2019 |
| Verizon | 2636 Alpine Blvd | sometimes zero bars, sometimes one. Can't receive or make calls. | 2015 |
| AT&T | 8706 Sherwood Terrace | Poor Signal strength. Constantly goes from LTE to a 4G Network to No-Service. | 2019 |
| T-Mobile | 267 Alta Ln | NO SERVICE WHATS SO EVER | 2016 |
