Way too many dropped calls on this section of Johnson Ferry Road. This is a major thoroughfare to East Cobb / Roswell suburbs, and AT&T ought to have it well covered, but they do not.

Only way I can make a call is with a wi-fi phone and it goes in and out and drops every call. Better than nothing I guess...

Inside my house (Hampton Glen subdivision) my SprintPCS service works great with very few dropped calls, work email sync'd to phone, and the occassional internet access. Very happy with clarity of voice signal and EVO for data is very fast here.

when I move here was using T-Mobile no service in my house if I stood out in middle of street on a good day I would get 2 bars of signal I went to Sprint PCS service is always good 4 bars signal I did talk to a construction crew that is putting a new cell tower up at cheatham hill elementary school said it was a new T-Mobile tower and said there would be 3 carriers on it t-mobile, sprint,verizion. said it should be operating by mid july 2008

Very little reception at my home off West Sandtown, near Villa Rica Rd. Also drops out at 75 / 285 near the Galleria.

T-Mobile Lacks in Signal Coverage. Very Dead in certain Places in EC or Marietta. Their Connectivity with RIM and BlackBerry Products not only won't let you make calls but it runs haywire with very unstable software and your applications will act on their own. A friend called me and said you just text'd me 24 times in the last 2 minutes... I hadn't used the phone yet that morning... Drop Call, Call Failed, Network Busy or Unavailable, Searching for Network and Cheer, aloud, when you get a single bar to show up... That Is My Experience with T-Mobile- If you enjoy the above Challlenges and Only need your phone to operate as a Calculator or Camera- (no texting pictures either) Then Go with T-Mobile in this area. I went to ATT / Cingular and it is as clear and dependable as my LandLine Home phone... fyi

Please don't be fooled by T-mobiles good deals. It's not worth all the trouble. I signed up for a trial period with them and I didn't get any reception in my dorm(Southern Polytechnic State University). I advise you to not use them if you live in the Marietta area. Doesn't matter what phone model you have because you will still have bad service in this area. Verizon has great service and I think that you would be best with that. I have never had dropped calls on Verizon. Their plans are a little more expensive but I'd rather pay more for services that work than less for service that doesn't work(huh..uh Tmobile).

Read a lot of cell phone reviews when I heard we were moving to Georgia (deciding between Sprint and Cingular). Very happy with Sprint- 3-4 bars inside my condo in the development, even more outside. Spouse's Verizon can't get any reception inside, drops calls constantly even outside. Verizon was the pits in Palo Alto, even with a different phone, too- why are they still in business?

Horrible reception inside my house. I have to stand near a window or run outside so I don't drop the call. Horrible. Definitely do NOT recommend AT&T.

Just moved out here a month ago and have no service with my T-mobile. I can't get call in my apartment, only text. Outside the reception goes up to 2 bars. And that's it. I've been in this place for a month and can only communicate on my cell phone using text messaging... if it actually will send out. I've been with T-Mobile 3 years, and never once had a problem. But now I can't use my phone. They are making me buy a phone that connects through a cable modem to see if that will fix the signal issues before they will let me out of my contract. They said they have sent engineers as they know they need two more towers in this area. Verizon does not work too well out here either. I'm at the bottom of Kennesaw Mountain so I'm sure it's an issue.

I have pretty good coverage. I do not drop calls in my home or outside. I do experience a dead spot on Riverside Drive, but other than that it seems to work well.

There is a couple of holes in reception around Kennesaw Mountain, but the phone stills seems to receive calls

I switched from AT&T (Cingular) to T-Mobile because of up to 19 dropped calls in one day. In 2006, T-Mibile reception was generally good (2-4 bars). However, in all of 2007, reception has become 0 to 1. This area is simply awful.

In this area it can go froma 4 to a 1 bar. Thank goodness for a 14 day return..Now what. Anyone like Metro PCS?

Excellent Reception. EVDO Broadband is great too.

Had no problems until 6 months ago.Get 1 bar 10% of attempts.Verizon just doesn't seem to care if I stay or go.I'll be leaving as will several neighbors when contracts expire.

Awful reception,even outside in yard.Verizon tech came and tested,and confirmed"lousy".They have a new tower in area.Follow up call from Verizon said I could terminate since it was a Verizon fault... but that I could not take my # to another carrier.When I protested she hung up on me.I will be leaving them after many years!Neighbors have same problem.

No Sprint reception around 1 mile before powers ferry / s.marietta intersection.

While I get pretty good reception on my commute to the top-end perimeter, my reception at home is poor. My home is located in a small ravine which is likely causing most of the problem. There are two hill-bottoms in my area that will cause you to lose a call when driving. My wife has a Verizon phone and seems to get much better coverage than I.

I have had FOUR different phones with Cingular and gone through numerous firmware and sim card changes- the coverage just sucks. I am constantly getting full bars up until the time I hit send. Then I drop to no bars or just one. Also, I am always having problems with dropped calls or more often being unable to complete calls with network busy or call failed errors.
