0 Out of 5 (0 stars) | El Capitan Dr. | Clearfield, Millbrae, CA 94030 |

Terrible reception, must stand out in the front driveway to make a call. Only time I get reception inside the house is on a clear sunny day, and at most just 1 bar. Phone to phone SMS is bad up here as well and email to SMS is completely unreliable and useless. Metro phones up here will discharge their battery supply in under 1 hour due to constantly searching for the local digital cell site.

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!

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.

Cell phone reception on Cingular around Pacifica seems to be pretty good. We ocassionally will lose reception going up / down parts of Sharp Park Rd. (only in one specific area, just below the house that sits above Sharp Park Rd.), and going up / down Highway 1 right below the 35 / 1 Interchange (on the downhill side coming into Pacifica). I can't tell if the loss of signal in those areas is due to weather or other factors. Reception will be lost if you go all the way up Oddstad Rd. towards the horse ranch, though.

Nextel service sucks everywhere. From SF-SJ along Hwy 280, reception really sucks. Two-way sucks just as much.

Poor reception on Dumbarton bridge and Menlo park area near the bridge. Get more dropped calls than good calls.
