Just switched from AT&T a few days ago and my Sprint service has been just ok. The phone is slow to open emails, AT&T iPhone 4 was much faster with that. Also my voice cuts out a lot when on calls and I hear it too. So far, not impressed.

AWFUL, no matter what phone device with AT&T. Going to switch to Verizon and see if that is better

While I might get average bars, the service is terrrible. I can't make calls most times and when I do they tend to get dropped. When I travel, expecially to an event with high turn-out, I am unable to make calls, data is non-existant. I hate ATT but have too many apps with iPhone / iPad that I hate to leave the handset. Verizon is much more expensive and according to the reviews here not much better service. I think I'll have to go to a satellite phone!

We moved here last week from Highlands Ranch. I have a Nokia phone, and T-Mobile coverage is nonexistent here just off of Ridge Road. If I can dump T-Mobile for another carrier, I will.

Lol... I was just looking at the coverage map and I swear my house is on the line where it goes from great service to poor. My neighbors and I all have commented on how bad the signal is on the south west side of Founders.

I get dropped calls all the time. I have bought a cell phone extender and will see if that helps but I love my phone but the reception in my neighborhood is horrible. If I go 1 mile I get better reception but in the family room maybe 1 bar at night. During the day upstairs gets two bars.

Read about the guy who moved His business from Colorado Springs to Castle Rock(From the colorado springs Posts andhere last Oct). Went into see him because my Verizon service, that works better than the others I had every where else, was awful in my house in Founders Village (Off Enerude). The last Poster was right, this guy is different and seemed to know his stuff. He said people come to him when they have reception problems with any service and are tired of the run around. Well, I was a bit skeptical but took his advice and bought this Nokia phone he said was best in reception, and my wife(She needed to have a flip) bought one of his Hybrid Motorolas(He makes them himself). Unbeliveable! I can now make phone calls in my house Without having to go out on the corner of the deck. This guy is a REAL phone expert and I suggest anyone with reception problems go see him. He's located in the Downtown area of Castle Rock on 4th St.

Followup from my posting on Oct 26, 2005, when I had a Motorola V540. Cingular is still the king. Can't recall my last dropped call. I get full and excellent coverage in and around Highlands Ranch, Castle Rock, all up and down the I25 corridor (even up to Cheyenne WY, where I go a lot). Even get great coverage going out and past Franktown to Elizabeth. I know equipment can affect service. I currently carry a Motorola V365, in the past 14 months I have carried: Nokia 6682, Motorola RAZR, Motorola V540 and V551, Motorola L2, Samsung X497 and X426. All of them except the Samsungs were perfect in reception and lack of dropped calls. I highly recommend Cingular with Motorola and Nokia products that operate on the 1900 AND 850 MHz frequencies.

I have been with Verizon for years now. It seems their Coverage is worse than ever. I had read about a guy in Colorado Springs on this site, who helped a few people with reception problems. He owned a store named Peak Cellular and Satellite in downtown CS. The last entry a few months ago mentioned he moved his business up to Castle Rock, but these Colorado Springs customers were still driving up to see him! This impressed me enough to check him out. His store is Downtown by the old Courthouse, 4th St. I think. Anyway, this guy really does know his stuff. Explained everything about cell phones (Just as those other posts said) and suggested I use this Nokia phone that hadn't been made in a year or so. It didnt have a PDA or camera but at this point I was tired of all that junk and just wanted to make a phone call. I couldnt use my Treo, Razr, or LG at my house. Because I wasnt due for an upgrade, I did have to pay the full retail price, but it is the best money I have spent since I got a cellular phone. Plain and simple, it works. It works in my house, in my car, and in many areas I had already accepted as a no coverage zone. This guy is the goods! This is the kind of small Cellular store we need to support, and forget all those other kids in the corporate stores that are just "order takers" as he put it. I will never go anywhere else for cellular!

The reception in and around Castle Rock has always been good for me and my wife. T-Mobile reception in other rural places has been poor.

No reception with T-Mobile. I have new phone, still doesn't work. I'm thinking of switching, but to what carrier?

I'm with Cingular since the buyout of AT&T Wireless. My reception is perfect all over the Denver metro area, I can't remember my last dropped call (couple years ago when with AT&T on 1900 MHz only). I recently drove from Riverside CA to Cheyenne WY and had coverage 95+% of the drive, I was amazed. My partner only had about 75% coverage on their Verizon phone. The 850 MHz band really makes a difference as it has much greater range. (I had to make this zip 80104 as 80108 is not recognized, but my zip is 80108)

I get no reception in this thriving community where rich people live. Can't send / receive calls or text. Data is useless in this area.

I get dropped every time heading up or down i-25 between Surrey Ridge and Lincoln.
