Came in with a locked eSIM on my phone after a failed attempt to switch to another carrier. Bryce met me with a smile on his face even after just dealing with a very rude customer. Within 10 minutes, he fixed my issue and I am back connected to my cellular network. Another confirmation of why I have been with T Mobile since 2002! View on Google

I had a great experience at this T-Mobile location. I came in because my phone had been getting really hot and the battery clearly wasn’t holding up like it should. From the moment I walked in, I was greeted right away and felt taken care of. This visit was for my plumbing business, so things were a bit more involved with multiple devices that all needed to be handled correctly. Nikki was the main associate who helped me, and she did an incredible job navigating all of it. She was kind, patient, and extremely knowledgeable throughout the entire process. She walked me through all of my options, explained everything clearly, and helped me choose the best solution without any pressure. Bryce also jumped in to help with my iPad, which I really appreciated. Nikki handled replacing my phone seamlessly, upgraded me to the newest Samsung available, and made sure everything transferred over correctly across all my devices. She also helped me get set up with a new iPad and made sure we had protective covers and cases for everything, which made a big difference. I really appreciated that they gave me the option to either head home and finish setup on Wi-Fi or stay in the store just in case anything came up. That level of attention to detail goes a long way, especially when you rely on your devices for your business. Overall, the entire experience felt smooth, efficient, and very customer-focused. Nikki really stood out and made sure I felt valued the entire time. Highly recommend this team if you’re looking for knowledgeable, helpful service. View on Google
