I used to live two blocks away and had very spotty reception. In my apartment now I have excellent reception and no dropped calls.

Verizon is the best in coverage. I do not need to carry 2 phones.

Verizon has good signal and coverage throughout the East Bay and SF. I've never really had problems with dropped calls or no signal.

I just switched to ATT / Cingular. The reception is 5 bars most of the time. Drops to 3 indoors far from windows or in the elevator. My phone has 2 bars in my basememt garage where I used to not get a signal with Verizon.

I've had few problems with reception here.

I am on the old AT&T TDMA network. Years ago I had Cingular and could not get any reception inside the house. I switched to AT&T and their TDMA network and it has worked perfectly everywhere for years, until recently, when calls are now starting to drop -- primarily on the west end of the bay bridge. Cingular is now phasing out the TDMA network, and after reading all of these comments, I'm sorry they are doing so, since from the sounds of it, this TDMA service is the best thing going in terms of reliability. What use is a cell phone if one can't get coverage in the house / office?

Until last week, was using older Ericsson phone on Cingular Service (maybe older version of Cingular) with NO reception on Thornhill above the 7-11. Now upgraded to new 2-yr contract with Cingular (probably newer version) with new Nokia 6102i phone with excellent reception all the way up Thornhill and in all rooms of house. Perhaps the newer phone is more sensitive. Conclusion... . dont blame the carrier without checking out their newest version and getting a more modern phone with better technology. Last week I was in a dark closet,,, now I can see the world!

Have excellent signal all the time

Never really had any problems with Verizon. Always works fine wherever I go in the bay area.

Coverage with T-Mobile in this area is excellent. The sound quality during my conversations is consistently good, and I never get any dropped calls.
