Pretty good coverage, AT&T just put up a new tower close by on rt. 7 which has brought much better signal to the area.

sketchy coverage throughout this area. Two bars in my driveway but little reception in my home. Had Verizon before and had much better reception.

Both Verizon and AT&T provide good reception in home. wife has a Verizon phone and I have the iphone

If you like the iphone and I love it then you have to put up with ATT. The reception is just plain awful north of tollroad outside beltway (odd as you would think that would be a target rich client base but I guess antenna's are fought hard). It is virtually impossible to have a conversation longer than 3 minutes (if at all) in this area. Had frequent problems in Tysons? and Tollroad near Wolftrap. The ONLY solution I have come up with: Keep the iphone for all the great non-phone features but buy a cheap Verizon phone for phone calls. I keep Verizon phone connected to bluetooth to the cars I drive. If you have to you can forward the calls from your Apple to Verizon number.

4 Bars out of 5 when I'm in my driveway. As soon as I enter my house its 2 - 1 or none Weak service area with lots of gaps in it. As soon as you get to i495 full service.

Only service provider that worked on campus

Cingular sucks in this area even though the tower is right down the road. Friends with Verizon can get about 2 bars sometimes. Sprint gets about 1-2 bars depending where. Cingular is just terrible at reception and customer service.

In the house, its pretty bad. I can make and receive calls ok, but calls will drop frequently, depending on the length of call. I have to drive over a mile in one direction to get more than 2 bars. So much for having an advantage living in one the richer areas of one of the richest county in america.

I have used Nextel, T-Mobile, and Verizon Wireless over the past five years. Verizon Wireless has provided by far the best coverage in the DC area. Nextel gave me the worst coverage, decent in the city but spotty in the suburbs and terrible the further away from the city I got, and T-Mobile was slightly better than Nextel. Verizon Wireless seems to work everywhere.

Poor reception along Kirby Rd.from 123 until Old Dominion.

Very bad reception in area. Constantly losing signal in midal of conversation, very frustrating.

No reception in house. Occasionally 1 or 2 bars but then call drops.

Works in the house and out of the house. Verizon does not work in the house but does out of the house.

Do not get reception hardly anywhere on Gerogetown Pike.

This is a TDMA phone - called #77 (non-emergency police) with no problem to report an accident. Tried calling work to say I would be late, got fast busy. It appears Cingular / ATT is quietly phasing out TDMA service (makes sense to phase it out, kinda bogus not to inform cusotmers of that).

T-mobile drops out on 123 near the CIA. Does any service work on 123? Works fine in NW DC. Works fine in the business district of McLean.

I just moved here from Louisiana. In Baton Rouge I had exceptional coverage with Nextel. Now in No. VA. it has turned to dirt. Frequent drops and bad voice compression. I am considering Verizon.

Absolutely no reception from Kirby road after getting off Chain bridge Rd, reception picks up only when one gets on to Old Dominion Rd. Absolute dead space for about 1.5 miles right in the heart of the beltway

Good service. No problems.

Most of McLean and Tysons Area is covered very well.
