1 Out of 5 (1 star) | Crestview Dr. | Btwn Brittan and Melandy, San Carlos, CA 94070 |

We're on the west side of Crestview and have been complaining to Verizon for better part of 6 years. I'm reluctant to change as I have several phones on my Verizon plan and it would be a headache to change them all. Verizon keeps telling me they're going to upgrade their tower coverage but, so far, only minor improvement. They also suggested I buy their booster which is $200.

Amazing... Silicon Valley... the place were new technology is created but the local governments can't afford to roll it out. Hows that iPhone work now? This place is just falling apart.

Spotty reception with 0 to 1 bars, inside or out. Dropped calls, poor sound quality. No wonder they have a 2-year contract. Sux!

Works most of the time but won't work sometimes for some reason, I'll have full bars until I send a txt message and then I lose most or all reception, this only happens in my bedroom upstairs and late night but this still shouldn't be happening.

I'm staying with some friends for the summer and just about every call gets dropped while the signal goes from 3 bars E to 1 bar G and then 0 bars of any signal. I've found the same signal issues coming anytime I drove down Junipero Serra blvd or Foothill xprssway and in Los Altos while visiting friends there. On campus it's fine, but anytime I drive back towards the house, the signal fades fast.

5 Out of 5 (5 stars) | VA Hospital, Menlo Park, CA 94025 |

I frequently walk / run the area around the VA Hospital while streaming music to my iPhone. When ever I look at the phone, it shows full bars and the streaming music never fails.
