My partner and I just moved to King Farm (Rockville, MD) from DC and haven't gotten a good signal since moving here last week. Only get 2 bars at the most. Could the power outages from late July, early August, have caused this (as the previous post suggests)? Or could it be our iphone 4's? This bites.

Since 2004 I've had constantly poor reception. Barely works in my basement or main level and I normally go outside if i'm going to have an extended conversation. 9 out of 10 times if I move around inside my own house the call will drop. Headed to ATT or Verizon next month. Would've done it sooner but my inlaws are on the same account and haven't managed to sync up the contracts until now. Bye Bye Sprint!

I'm astonished that I'm so close to major technology centers and the nation's capital but cannot get cell phone service. I had service at Tahquamenon Falls (in upper peninsula Michigan)!

Very bad reception, then the phone keep looking for signal and kills the battery in 4 hours or so. I used to have Nextel I730 with very good signal inside building but I wanted to try with nice looking phones. I shouldnt do it.

My phone uses the 1900mhz band and I get 1 bar to mostly 0 in my house and in quite a few areas around it. 850mhz band in dual / quad band phones is fine though.

I generally have great reception in the Germantoan + Gaithersburg + Rockville area. Been with VZ for over two years now. Overall, maybe a handful of dropped calls in that period, including travelling to the west coast. However, on the ground level of my 3-level TH, there are a couple of dead spots - very wierd. The dead spot would knock the signal to 1 bar and sometimes drop the call. I'm out of contract right now. I plan to switch to another provider soon because I entirely detest VZ's fraudulent approach to crippling the industry standard capabilities of the Bluetooth so they can profit. For those who don't know, VZ disables the ability to use bluetooth to transfer files between the phone and the PC. You're forced to buy their ringtones and graphics instead. You cannot directly transfer pictures taken with the phone to your PC.

I get intermittent reception in my home where it can go from full bars to one bar in a flash and then back to 3 bars where it is most steady at, my data also does a dip from EV-DO to 1X and back. I used to have full bars all day every day every where until a couple months ago.

The Motorola gets awful reception in these areas with frequent dead zones and dropped calls. Poor clarity as well. The Nokia is gets much better reception but is still at 2 bars or less.

Calvin Lane, Rockville, MD 20851 Wed Jul 05, 2006

Suddenly, since yesterday, I am unable to make calls in and around my home -- after trying to connect, I get a message that says "svc unavailable." Repeatedly. Don't know if this is a problem that will correct itself after the holiday or if I need to switch carriers.
