AT&T

I’ve been in to this location a few times in the last year — to look at phones, to purchase smartphone accessories and for technical support. All have been fairly good experiences. In January, we met with Chad to look at smartphones and couldn’t find exactly what we wanted. Finally, in February, a new phone came out, but they didn’t have one in the store. Luckily we thought to call some other stores, found them in stock, and bought them elsewhere. We’ve been back to this location with our new phones a few times — for technical support — with no «you are bothering us» vibe. Even when it’s that you just need to reboot your phone to make it work (seriously, is my Smartphone running on Android, or Windows 3.1 :-p) They are fairly busy, so be prepared for a wait. I went in to purchase screen protectors (nearly impossible to find via 3^rd party yet), something that should have taken 5 minutes, and ended up being there for 30.
Like all carrier-​branded stores, the accessories are ridiculously overpriced. If you have something like a iPhone that is high volume — you can easily find cheap accessories elsewhere. They have to pay for their fancy recent face lift somehow.
