1 Out of 5 (1 star) | Mariners Island Blvd. | E 3rd Ave., San Mateo, CA 94404 |

I've recently moved to this neighborhood. My AT&T reception is horrible. People constantly complain about me breaking up and they eventually hang up.

I have AT&T service and an iPhone. As soon as I get into Belmont, my signal strength drops until I pull into my driveway. Then the signal disappears and my connection is gone. I have to go from room to room to outside and then back inside to be able to barely talk and I pay a lot of money for a service that doesn't work. I want to switch but doesn't seem like any carrier has good reception in Belmont... So frustrating... .

1 Out of 5 (1 star) | Marsh Rd. | Bay Rd., Menlo Park, CA 94025 |

I get 1-2 bars outdoors in the middle of the street, and 0-1 bars indoors. When the phone rings, I have to run outside to have a conversation, and even then it is shaky. AT&T says I should have 5 bars, but that is pure fiction. We have tried two other phones, and they have the same problem.

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.

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.
