Long stretches where I get one, maybe two bars. Routinely unable to make calls from in front of the house. Often, people say they have called me, but no record on my phone.

Good Bye AT&T; I will switch to Verizon or Sprint for my 4GS... and because the phone provides courier options, I will switch again in two years if I get bad reception!

Almost no reception anywhere in my house or outside around my house. It wasn't this bad a year ago. What the heck happened AT and T?

Never more than 0-1 bars in my house. It's terrible reception pretty much everywhere (although it does work much better outside 2-3 bars). Go with Verizon, do not get stuck in an AT&T contract if you live in Frederick, MD.

my phone allways says no network 0 bars I have been fight with them for a couple of years now. and they have no solution so I must have a landline phone in my home

My phone gyrates wildly between 5 bars and 1 bar inside and outside my house, even while I'm being still. The real average reception is 1 bar. Constant muffled and stuttered voice reception with predictable drops during the afternoons. Inside or outside the house, it doesn't matter. Even if I drive towards Hwy. 15 on Opossumtown Pike the situation is little better. In fact, reception remains muffled until I hit the Key Mall. From April 17th until April 21st, my cell phone service was totally unusable, even for retrieving voice mail, even though I had "3 bars". That's a shame since Cingular works so well in the Atlanta area. I guess you can't travel, have just one cell phone, and expect to have any reception.

The service never drops out only because the tower is about 1.5 mi. Away

AT&T Wireless has dropouts at the following locations along Interstate 70: at the Baltimore County line between the Beltway and US29. Near Turf Valley (where US40 comes in and joins, near mile 82). At the Frederick County line near Mt. Airy. Near Spring Ridge (Mile 59). Near New Market (Mile 62). Along US340 and US15, there's a severe dropout atop the ridge near Jefferson, MD - the call will drop every single time and 200 feet later you'll have five bars. I've been with AT&T for three years and this has never changed in the slightest.

My calls frequently drop even when I'm in my house. Frederick, MD isn't a good area for Sprint.

I had Sprint in Chicago and moved to Frederick about 9 months ago. While I never had a problem in chicago, around here my signal strength varies wildly, even sitting still in my apartment in town. Calls frequently drop or sound garbled. I haven't encountered a "dead zone" with absolutely no service, but it is utterly unreliable. With my plan expiring this summer, I'm definitely in the market for a new carrier.

Mostly bad reception. Some parts of Frederick are dead. Sprint plays hard ball. Expect no sympathy and no getting out of your contract, sucker!

I have to go outside or stand next to my front window facing the cell tower which is located near Ft Detrick. I get 1-1 / 2 bars if I go to my second floor window. If T-Mobile is rated the highest, I feel sorry for the rest.

Just purchased a new Android smartphone thinking I would get better reception... .not so. Still only receive one bar in my residence even though I am located within.3 miles of a T-Mobile tower. Frederick County and City need more towers. Service will not improve with merger of ATT and T-Mobile since both companies have only one tower each in locale and ATT is rated lower than T-Mobile on reception scale.

4g data fades in and out between 4g and edge networks. Sometimes slow to connect. I was trying to locate where T-Mobile cell towers were located. It looks like frederick only has 1. It would be nice if there were more.

I had T-Mobile in Mount Airy, MD and had no service inside of my house, and moved to Frederick and now I get 3G service. In Mount Airy, I would have to walk outside of my house at least half mile to get service!

usually have 2-3 bars out of 4 for voice plan. edge service slow to connect sometimes.

I have poor coverage in Frederick, MD... . as well as DC. Some places are great, other are horrible. I see people chatting or surfing in areas where I don't get coverage. I'm going to start asking them who their providers are. I came here looking for guidance, but all the info seems dated.

Nothing. Park users, especially mountain hikers and bikers, need good communication to get help in case of an accident. I understand all carriers have very poor to no coverage up here. Certainly, not one is reliable.

I travel between Frederick and Rockville, MD every day for work and I never lose reception while driving within Montgomery county and Frederick County. I even drive a lot between Frederick and Hagerstown and have never lost a signal while on I-70. I can use the phone anywhere in my house in Frederick, friends' houses in Hagerstown, malls in Frederick, and even in my office building in Rockville. The Nokia 3650 I use is amazing and always has at least 3 bars for signal no matter where I go it seems, which is a lot better than AT&T service around here. If you live in Frederick, definitely check out T-Mobile and the Nokia phones.

Never had a problem with reception whether I am in a large building make of steel or outside anywhere I always have good coverage. Since they have capped the 3G data I have had a big slow down with that though.
