I have always been happy with my T-Mobile service. I have used them for about 6 years now from when they were Voicestream and the coverage has greatly improved. I travel all over the US and rarely loose coverage. I love my rate plan and the customer service can't be beat!

Switched from Sprint to Cingular. Sprint worked indoors and Cingular is terrible indoors. I will probably go back to Sprint. Cingular is patchy, their HS data package is slow and they are not exactly doing a great job with customer service so far

Calls don't get dropped too often (much less often than when I had AT&T GSM) but quality is consistently very poor.

Have to cancel within our 14 days. We had 93 calls on the family plan and not one went with out being dropped. We are going back to Verizon since we always had reception in this area. We do lose service heading north on Centenial and then hit a brief, about 2 blocks, of roaming on Centennial near Trail Blazer Elementary School.

The only cell companies that really work at my home are Cingular and Nextel, that I know of for sure. I do know Verizon, Virgin Mobile, Sprint, Qwest, and AT&T DO NOT work here (0 to 1 bar).

Possibly the worst cell coverage anywhere I have been in the world.

Cingular reception is slim-to-non-existent at my house and the surrounding area around Mountain Shadows, Mount St. Francis, Vindicator, Delmonico. I plan on switching back to T-Mobile the day my Cingular plan expires. It can't be soon enough.

I have had T-Mobile for 4 years and have received nothing but excellent service from them, that is why I keep extending my contract. Great, reception, I live on a ground floor and use my phone with T-Mobile service for my laptop, no problems!

I've been putting up with Verizon and their promises to improve cell service for about 4 years now and I'd swear their service is deteriorating. If it weren't for the fact that every time I start researching other companies, I hear they have the same problems I would have dumped Verizon long ago. I even bought a bi-directional amplifier for my car and it helps a little but not enough to really make a difference. Oh well...

I previously lived in Philadelphia and had T Mobile phone service, I was very happy with it, unfortunately my husband and I decided to get a family plan and so I swtiched to Verizon. (He still apologizes for making me switch!) We bought our phones in Georgia and wanted to get a Samsung, but the sales rep in the store warned us that she had a "bad batch" that had quite a few that had been returned. She urged us to get the LG 6100--BIG MISTAKE. I had horrible reception in Philadelphia, ultimately they finally replaced the phone with the same phone, a cycle that I repeated regularly. Every time I made a call, it seemed like it would drop. I have spoken to so many Verizon reps that I feel like I know more than they do. Since moving to Colorado the service has been equally horrible. I brought it to a Verizon store, where they told me that I would have to switch to a local phone number (THEY WERE WRONG.) I corrected the lady I spoke with, and ultimately she came back and apologized, telling me that it shouldn't matter... she did however replace my phone again. Now that I have had the same phone 3 times, I am finally elligible to switch a different phone (OF EQUAL VALUE.) They told me I would have to go to a Verizon store to do the switch (which I'm dreading.) Hopefully a different phone with improve the problem, although I am very skeptical and am overall very unhappy with Verizon: the tech support is horrible, the customer service is horrible, and the phones and service are horrible. I'd avoid Verizon if I could...
