Used T-Mobile for 5 years. Loved them. Recently moved from East Village to Pacific Highway. Zero reception in our building ("No service") with my Treo, and very rarely will I get a single bar outside for about the 1 / 2 mile stretch between Broadway and Laurel. Wife occasionally gets a single bar out on the porch with her Samsung. Looks like we're going to have to switch carriers, which is unfortunate :-(

I get 4 bars regularly inside my apartment.

I can't get past one bar on multiple cell phones. It sucks, but their technician says the area has no problems. First Ave, Banker's Hill

Sprint PCS basically sucks everywhere in San Diego. AVOID!

In my 17 story building reception is always perfect, even while riding the elevator up there is no service interuption.

Poor reception inside 5 story building. Have to hover near window to get any signal.

T-Mobile has great reception even in my 5 floor apartment building. I hardly even have calls dropped.

Up until 2 weeks ago, my reception had been quite good inside the apartment for 2 years. Now, I cannot even make or receive calls at all inside. My street is very spotty, too, suddenly. My coworkers' Sprint PCS phones work great for them, especially inside the hotel where we work, and in the service elevators.

Lots of dropped calls. Sometimes phone doesn't even register a missed call. Voicemails get delayed by hours. Voicemail doesn't always pickup. Bad reception during calls. 3G service is a joke - I have to turn it off in order to get any phone service at all.

I have the iphone on the AT&T network and live in the Balboa park area and I get tons of dropped calls and poor call quality. I'm switching this weekend to Verizon, maybe?
