1 Out of 5 (1 star) | Dartmouth | San Carlos Ave., San Carlos, CA 94070 |

This phone worked fine in my house more than a year) until last week. I guess AT&T converted the TDMA tower to GSM to keep me happy - NOT!

AT&T Wireless (GSM)

0 Out of 5 (0 stars) | Reina del Mar | Hiawatha Ave., Pacifica, CA 94044 |

No reception at all (both GSM and TDMA) with AT&T wireless up here in the Valle Mar area. It comes in as you get closer to the intersection of Reina del Mar and Hwy 1.

0 Out of 5 (0 stars) | I280 | From Daly City before Geneva Ave. Exit, Pacifica, CA 94044 |

I get drop calls whenever I pass this certain part of 280 coming from Daly City just before Geneva Ave exit. Also I have another drop calls coming from 280 and exit Hwy 1 to go to Pacifica. I think that area needs some fixing by Sprint. Other than that Sprint has good service.

Sprint has a Dead zone on interstate 280 from Daly city just before you hit Geneva Ave. Also Sprint has a deadzone coming from 280 exiting towards Highway 1 to Pacifica.

No signal from Verizon. Some time the roaming doesn't work either.

1 Out of 5 (1 star) | Hesperian Blvd. | Industrial Blvd., Hayward, CA 94545 |

New housing development built in the area. Barely any reception in that area and on Hesperian heading south... which eventually turns into Union City Blvd. All along UC Blvd you're lucky to get a bar at all.

4 Out of 5 (4 stars) | Humboldt Rd. | Kings Rd., Brisbane, CA 94005 |

Depending on traffic on 101, reception is good except rush hours. 3 bard generally. Much better than the lower parts of town, I think.
