1 Out of 5 (1 star) | Seville Dr. | Oviedo Ct., Pacifica, CA 94044 |

Reasonable outdoor reception. Poor / Very poor indoor reception. AT&T tower is on Montara peak so the steep hill west of Seville is likely weakening signal.

Terrible coverage in downtown San Carlos. Shows 4 bars and LTE but will not load webpages or apps. Has gotten worse in past year?? Often have to switch to 3G

Have had Verizon for over 6 years. This last year started working in San Carlos. I have 4 bars but dropped calls all the time. I have LTE but can't load websites or check email. Seems like no carrier has their act together around here.

1 Out of 5 (1 star) | Palm Ct. | Stanford Ave., Menlo Park, CA 94025 |

Terrible! 1-bar. 2-bars occasionally. When I upgrade my iPhone I will be gone to Verizon. After all, this is the center of Silicon Valley! Also had to return AT&T microcell. It would not lock on poor AT&T signal.

Sprint sucks and the only reason they get service is because they roam and use verizons signal because they use the same cdma technology
