Oct. 1, 2010 update: T-Mobile has refunded the contract termination fee they charged me for ending service with them. It took an intervention by a friend who knew someone high-level within the company. But since I have gotten the result I have sought, which was a refund of the wrongful contract termination fee, I am removing the Boycott T-Mobile banners from my websites.
If you're thinking about going with T-Mobile for cell phone service - DON'T. After what I've been through with them the last few months, I've figured out their customer service attitude right now is one of the worst among phone companies. If you get a bad phone, one that was released before most major technical glitches were worked out of it, they will not let you out of the contract until you've exchanged the phone at least three times. If you thought you would resolve all of the problems eventually so you didn't return it within the 30-day window, you're out of luck and they will not let you out of it, no matter how many letters you send back and forth and how much evidence you provide that the phone is a dud.
The Motorola Cliq phone I purchased from them dropped calls constantly - 58 times in one month I checked, including five times during one single call to a landline (see documentation below)! It "ghost-dialed" numbers several times a week. It would be sitting on my desk and randomly start dialing people who had recently called me - including a stalker and a job interview. It ghost-dialed a friend of mine at least three times in one afternoon. Others have reported this problem. I returned the phone and the new model continued to have the same problem, although not quite as often.
I never was able to get my email account to work, another known glitch with the phone, even after an hour on the phone with their tech support, which couldn't figure it out either. I spent easily over 25 hours trying to get the technical glitches with the phone fixed. There were many other technical glitches, too many to list here.
T-Mobile refused to let me out of the contract no matter what, even after I contacted the Better Business Bureau, and even though there is plenty of information on the internet about the terrible problems with this phone. I have sent them two long letters, which I CC'd to the company president, detailing the problems and a spreadsheet of the dropped calls. Now they are coming after me trying to charge me a $303 contract termination fee. Their approach was to blame me, the customer, accusing me of not spending enough time with their tech support and not canceling within the first 30 days, and telling me that many dropped calls was normal! Never mind the fact my phone prior to that with them never dropped calls.
If this is the way they want to do business, I think the public has a right to know. I would advise everyone to stay away from this company and stick with Sprint or another company that does not instruct their employees to use this aggressive way of going after their own customers. There is a certain level of service that is completely unacceptable by the vast majority in society's standards, and to go below that level is to commit contract breach.
Here is what someone else had to say about this phone:
