Well, as it happens I work for T-Mobile, and I’m perfectly willing to answer questions. I’ve also had the service for over three years and wouldn’t switch with a gun to my head. As a basis of comparison, I was with Verizon for three years before I switched over. No, I do not have an employee account as I got the service before I hired on with the company and I prefer to keep my advantageous rate plan especially because as a regular customer I get a better deal on upgrades.
Malkavia: If you have a SmartAccess account (with a spending limit balance) that would explain why your phone doesn’t work in Mexico. There’s no physical reason why, as TMo USA and Mexico are both running on 1900Mhz frequency. If you do have this type of account and have been with TMo for more than a year, you might be eligible to convert to a regular account which does allow international roaming and dialling.
ShibbOleth: Sorry about your activation fee issues, but I think you’re probably right that an indirect dealer set you up to run afoul of the adjustment policies in order to make sure he didn’t get a chargeback on his commission.
We don’t inflate our coverage area, and the map on our website is interactive and is not only accurate to street level, it’s also the same map we in customer care use to diagnose service issues and report them to the engineering department. Any place I have issues with coverage I’ve been able to check on the map and see exactly why there’s an issue in that spot.
One of the major business pushes for '06 is expanding and enhancing coverage in suburban areas. We’ve spent a lot of money doing exactly that, and have met or exceeded all projected forecasts for network enhancement this year.
We’ve won J.D. Powers and Associate’s award for top customer service three years running, which is an industry first.
When I started with the company in Q1 '03, we had just amazed the heck out of ourselves by exceeding our target growth in customer base–we’d hoped to end Q4 '02 at eight million customers, instead we ended with ten million. We’ve more than doubled our customer base since then, and it’s all been the old fashioned way. We have had no mergers or acquisitions to explain our solid growth.
We offer an excellent product at a more than fair price. Our handsets are competitive, and we offer more minutes for the money than any other national wireless carrier. We’re extremely competitive in our data plans and features as well, with EDGE deployed in all markets and unlimited data features mean exactly that–if you want to hook your phone up to your computer and use it as a modem 24/7 we won’t stop you, or charge you extra, or cancel your service like some other companies I could name.
Our text message packages start at 4.99 for 400 messages, and that’s either SMS or picture messages, we don’t differentiate. Unlimited texting on a single line is 14.99/month, or 19.99 for up to five lines on a family plan.
We’re testing a “5” plan in two markets currently (Portland OR and San Diego) which allows unlimited calling to any five phone numbers the customer chooses–landline, other wireless carrier, anyone.
The new 19.99 “KidConnect” plan has unlimited weekends and mobile to mobile calling, and up to $20.00 in any other service, 75 minutes, or 200 text messages, or any combination thereof. More money can be added to the plan as needed, with refills done like a prepaid phone. It’s targeted toward teaching kids how to handle a cell phone without bankrupting Mom & Dad, but it’s also pretty spiffy for low usage needs adults.
The MDA and SDA PDA/Smartphones are the whizbang shiznit on a whirling carrot with icing, and I’m trying to decide which one to get as my next upgrade. 
And yes, T-Mobile USA is a subsidiary of Deutsche Telekom, and a very profitable one at that…
