I've had AT&T for 5 years and think they get great coverage provided you don't have a cheap phone. I unlocked a Samsung Memoir from T-Mobile so I could use it with AT&T and don't remember the last time I dropped a call. The call quality is amazing as well and it's as clear as a landline almost all the time. But once again, AT&T's quality is directly related to the phone you're using in my opinion.

T-Mobile never works. It is constantly saying 'emergency only' use and drops calls all over. I am in a major residential area and this should not happen! Paying $400 to get out of contract! DO NOT USE!

I am particularly mad about my reception. Within the ATT contract it states that if I move out of the coverage area I can cancel. Well I haven't moved, I signed a contract only to find out that my neighborhood has the worst reception ever. No actually, I can truly say that AT MY HOUSE (the place where I am most) I get 0 reception. I tried canceling the contract, but the bastards just tell me that I have four bars when I call them to complain. ATT, you are Sh*t.

I used to get fantastic reception at home, and at school. But Now I am lucky to get one bar next to a window. One friend has the exact phone model and carier and gets more bars than I do when our phones are right next to eachother. My phone has recieved no damage, but I can't make any calls. The battery gets drained because it is always searching for a signal.

spotty phone calls, lots of texting in spots, decent internet when camped at the right spots

Service here sucks, Upper cottonwood Heights. 90% dropped calls.

I have 4 different spots in my 800 sq. ft. apartment that, once entered, will disconnect my call. At work on the east side, random dropping of calls.

I get great reception here. once in a GREAT while a call is dropped. Some of the people I talk with on the phone say the reception is muffled. This could be their phone model though, because not all of the people I call say this happens. but all around... I have had no problems with At&t. and I travel extensively.

I am a real estate agent in SLC and I have a BlackBerry curve with Verizon that is very spotty. it will show 4 bars of reception and not connect for calls. all over the valley is moderate, but at my home in holladay I get 4 bars standing outside, and go to extended network in my house with NO DATA! Verizon needs to update their technology considering not everyone is always outside.

I Live in the Harvard-Yale area of Salt Lake and work downtown in the Key Bank building, and I get very good service at work, and at home. However, no 3G in SLC from T-Mo... EDGE works okay for now...

Sprint is awful in this neighborhood. I am lucky if I get one bar a month. When I do actually get reception, the call will drop within minutes. If you live in this area, go with another carrier.

T-Mobile in 84121 - no bars. Worthless. Have to walk a quarter to a half mile to get reception some days. Works fine, other places in the valley. I gave up on them.

I'm not a big phone user so got the cheapest nationwide plan possible, planning to use the phone primarily for free long distance to talk with the folks once a month. But my calls get dropped every 15 minutes or so, regardless of closeness to interference sources, etc. Matter of fact they get dropped anywhere in town. Worked well in DC, though. But I don't live there.

Constant dropped calls and interference with reception.

Constant drop calls on I-15 between 1300 S and 2100 S. And also in West Valley City.

Very Poor! Numerous dropped calls

Doesn't get reception at my cube: goes to voicemail and then get a ring and must go to window. Strangely enough, at another indoor location at my work, I get reception good enough for talking, if you stand in the right spot. In this location coworkers with T-Mobile or ATT get good reception (4 or 5 bars), and can answer calls from their desks.

Zero signal in the basement, 2 bars upstairs, and only 4 in the wide open. This was happening with my Sony Ericsson T637 as well, so it's nothing to do with the iPhone not being used with A&TT

Purchased cell phone for girlfriend with warranty. Manager of Cricket store on 700 East and 2100 South said he didn't have time for me. He was busy talking to friend about Jazz game. Good thing no contract Thanks T-mobile

Dead area on Holladay. Very frustrating.
