T-Mobile

Wanted a change on my phone caller ID. They promised to do it but after two weeks and 4 follow up calls, nothing was done. Twice they promised a manager would call me as they were too busy at the time. No calls. I am very disappointed in T-​Mobile. I would not recommend this company. Sno

For simple things they are easy to deal with, but the plethora of policies that require their manager to be present (he is in only till 1pm according to the employees), makes dealing with T-​Mobile in this store as unpleasant as in any other store like in Crossroads and Redmond Town Center.

Really not impressed. I decided to take my iPhone 6 no-​contract ordered from Apple there to be activated rather than doing it by phone. What a mistake! I was there a few days after the iPhone 6 came out and this was a mad house. They had some extra staff to handle the overflow but this took forever just to active the phone! I didn’t even transfer my number, the sales guy had 5 minutes to try to sell me a bluetooth speaker which would add $ 5 to my bill but not time to wait for me to get my billing password from Verizion to switch my phone over. I wish they had a bigger store, like the AT&T one down the street. Oh, and I got charged an extra $ 10 for a sim kit when I already had a sim card in my phone (fishy). All in all I attribute this event to the fact the iPhone 6 had just been out and things were a bit crazier than usual.

I wish zero stars was possibility.
I just switched back to ATT after 4 horrible months of service with T-​Mobil. Calls were regularly dropped. I often had no signal at home, at work, pretty much anywhere.
When I went to the T-​Mobil store to get my phones unlocked to return to ATT, they suggested I buy an android phone. Yeah right.
When I called T-​Mobil customer service to get a refund for 4 months of this shit, they asked why I didn’t call in to report my issues. How could I call in? How?
Don’t do it.

Recently switched from AT&T to T-​Mobile.
I had to go to a T-​Mobile store to get a new SIM card for my phone. Visited this location at The Commons on the Microsoft campus. AT&T, T-​Mobile and Verizon all have stores there, which makes it very convenient when you have an issue with any of these carriers.
My experience was similar to the one that I had at the AT&T store two spaces down. It was pretty straightforward. In order to get the new SIM card, I needed to provide the temporary phone number I was given (while my current number was being transferred over) and show photo ID. I was in and out of the store in 5 minutes.
I like this store because the staff seems pretty knowledgeable. Expectedly more so than at a retail store given the clientele at this store are primarily techies. If you work on campus at Microsoft and have any issues with T-​Mobile, I would visit this location since it is less crowded and the service is likely to be better than what you would find at other T-​Mobile stores.

Avoid Avoid… wife went to add a line. Sales Rep that starts with a D (I am not going to use her real name) cancelled my other two lines… next thing you know I have three two year contracts. Less minutes. Next day I get a text saying I am $ 350 over in minutes and
I am 507 text messages over. I even talked to D over the phone and told her not to change my two other lines because I need unlimited minutes/​texts. Today I spent over a hour on the phone with T Mobile getting this fixed. 7 calls later it was back to what it should be. I would expect this to happen at a strip mall with a authorized sales person not at a corporate store. Really poor customer service and a sales rep just trying to make her numbers. Thank you D for taking care of the customer.

This store knows what they are doing and defies the «slick salesman» stereotype that defines most cell phone salespeople.
If you are a MSFT employee, and ever have a need to add a line, change your plan, or need support of any kind, come to this T-​Mobile store located in the Commons. That goes double if you’re trying to resolve an issue that the folks on the phone can’t solve. They know how to cut through the bureaucracy and can get things fixed for you in a jiffy. I’ve had billing/​plan change issues that were fixed with a few keystrokes here that were too hard for the call center or the RTC store to fix.
It’s been the same few employees since the store launched, so they are super familiar with the MSFT handsets and deals. You can’t go wrong.
