I switched to Cingular about two weeks ago. Calls from approximately 800 E. and 10800 S. are very poor in quality - even when outside. I cannot get a signal most of the time from the basement of my home at that address, and when calling from the main floor the person on the other end of the line often complains (if they haven't been dropped prior to being able to complain). I spent an hour on the phone with Cingular customer service yesterday. Their solution: Have more customers log complaints to Cingular and after they get enough complaints they might be able to send out a technician to check out the area.

In our experience, Cingular GSM has the worst reception / transmission of any carrier in the Salt Lake market, and their customer service is equally dismal... don't waste your time with these guys; it's not worth it for all the dropped calls, garbled conversations and 30 minute wait times with customer service...... their attitude is best summarized "we're too big to care" We'd highly recommend TMobile, Verizon and Qwest, in that order, for transmission / reception and voice quality superior to Cingular...

Coming up to redwood road on bangerter HWY I get poor reception around the river bottoms. I also get poor reception around 10600 So and 700 E. I use to love AT&T wireless. But there new GSM network sucks!

AT&T TDMA / AMPS provides very good coverage in this area including up the Cottenwood canyons and the ski resorts. The canyon reach may be due to AT&T phones ability to use the AMPS analog network which has greater range than the digital nets. However, AT&T TDMA / AMPS is being discontinued by 2006 and may degrade between now and then as Cingular converts the AT&T TDMA and AMPS 800 MHz to GSM 800. So TDMA customers accustomed to excellent coverage have to switch to something with inferor coverage. From what I read and hear, Verizon offers the next best coverage and theoretically does provide AMPS for rural area coverage.

I have used all of them here in the Salt Lake Valley and even though Verizon does have it's reception problem areas, they are still the best. I use close to 4000 minutes a month and have dropped less than 5 calls in one year. Great signal everywhere, Verizon is the only reliable service at my house in Willow Creek; works great out in Magna areas as well; even made phone calls at Kennecott's copper mine where my Sprint, T-Mobile and Cricket phones had no service. Signal reaches in very far into Millcreek Canyon; the best, most reliable coverage in most canyon and ski areas; driving out to Wendover service is good as well; driving to Moab, the only big dead spot is in American Fork Canyon( but every carrier has that dead spot). Then solid coverage towards I-70. So even though Verizon will have some small reception problems, overall they are the best network here in northern Utah. Btw, I get full reception at 9000 South and 700 West, Verizon has a cellsite at 9000 South and I-15 so coverage in that area is rock solid.

GSM coverage is poor to nonexistant throughout east Sandy. From what I can tell the only tower in the whole area is by Altaview Hosp at 94th South, 13th East. Our only hope is that AT&T will beef up the coverage in this area. If you've also had problems with this area go to this link and report your difficultly. Strength in numbers! Otherwise, I've found the remainder of the SL valley GSM coverage to be great.

This area by Little Cottonwood Canyon has poor to no cell service. AT&T / Sprint PCS / Qwest cell phones have worse service in this area.

No reception in store and school which are all in this area. Outside reception is below average.

AT&T GSM network what a joke! Just plain poor with no hope of getting better.

I've tried Sprint in Salt Lake and service was okay, but nothing too special. A few dead spots I found with Sprint in the Salt Lake Valley: Union Middle School (no service in most part of the school), Hillcrest High School(very weak), Gateway Mall (all or nearly all stores are dead), the ZCMI Center has lots of dead spots for Sprint, drving on 7th East from Fort Union towards 6600 South calls drop nearly every time right before you cross I-215, Big Cottonwood Canyon is totally dead right after you enter the canyon (Verizon's digital service reaches much further into the canyon), also in Millcreek Canyon Sprint service is gone right away while Verizon reaches in very far (and so does AT&T TDMA) and there are many more. Sprint coverage in the Salt Lake Valley is all right, they have a lot of room for improvement though! I'd recomend Verizon for Utah, Cricket, though, is also quite strong here in the Salt Lake Valley. I never had a network busy message when using Cricket. Only thing to be carefull of is that they do not work at the ski areas and don't even provide continous service along I-80 to Park City.

Calls were dropped very frequently (more than half the calls). I had SprintPCS in the same area and had very few dropped calls and have now switched to AT&T and so far, so good.
