1 Out of 5 (1 star) | Highway 280 South from Daly City to junction en ro, Daly City, CA 94015 |

On Highway 280 South, heading towards the junction in San Bruno to get to 101 South, you almost ALWAYS drop calls. Whether it be GSM, CDMA or TDMA. Daly City area is a terrible digital area.

More times than not, will lose reception when going over bridge. Same for AT&T.

Reception on T-Mobile is spotty in general, but it hardly works up here on the hill. AT&T (TDMA), Verizon and Cingular GSM work fine up here, and even Sprint had better reception than this. I have to go outside and stand in the backyard in order to make calls. I'm never getting another T-Mobile phone, that's for sure.

Spotty coverage on Highway 280 in San Bruno area. Traveling northbound, calls tend to drop or fade out until you reach Daly City / Serramonte Blvd. Southbound coverage hit or miss, sometimes very good, other times calls will drop out.

There is one spot in my hallway where I sometimes get patchy reception, but no where else. Going outside doesn't help at all either. I used to have a Nokia with AT&T and got no reception at all.
