My T-Mobile experience at this Costco was unpleasant, to say the least. My interaction was directly…read morewith their site manager, Charlie. This review isn't about T-Mobile's overall reception -- it's strictly about the in-person customer experience at this location. My iPhone 16pro and Apple watches are paid off, purchased through the Apple Store, and fully unlocked -- in theory, this should have made for an easy, straightforward switch. Instead, the process became overly complicated and time-consuming, proving that even with "ideal" conditions, execution at the counter can make or break your experience. My Issues with Charlie (Manager) * Competency: Frequently asked another employee for help (a good trait in itself), but still gave me incorrect info and made preventable mistakes. * Misinformation: Told me stand-alone Apple Watches were 5G -- they're 4G. I actually asked this as a "test question" to gauge whether he was full of it or just misinformed. Unfortunately, his confident but wrong answer -- paired with a made-up justification that "you're getting 5G service so it's 5G even on the watch" -- showed me it was either a lack of integrity or another example of incompetence. Tip for consumers: You can easily check what kind of connection your watch or phone is using through the T-Mobile app, so you don't have to rely on sales floor claims. * Execution Errors: Switched over a watch I had specifically told him to leave on Verizon. Was this an intentional sabotage? No-Charlie seemed like a decent person -- but it was a combination of over-promising, under-delivering, and sloppy execution. His demeanor cooled after I canceled two watches, which I can understand from a sales standpoint, but it's his weakness and unprofessionalism to let it show. Complicated Switch = Time Commitment If you're adding or switching other devices, especially stand-alone cellular Apple Watches, expect a longer process: * One phone + multiple stand-alone family Apple Watches took over 2 hours for one watch to be switched. * I canceled two watches mid-process due to lack of confidence and time. * Expect 30 minutes to over 2 hours per watch depending on complications. Other Situations That Can Cause Delays 1. Your phone is locked to another carrier. 2. Your phone isn't fully paid off. 3. You're switching over multiple device types at once. Bottom Line 1. Promos: Costco's T-Mobile deals are usually better than standalone stores. 2. Time: Simple phone switch = quick. Multiple device types = 2-3 hours. 3. Check: Double-check every line before you leave.

We would like to take a moment to recognize one of the team members by the name, Brandon, at the…read moreT-Mobile store at the Lakewood Center Mall location this past Tuesday, 4/28/26, for his outstanding customer service. My wife and I recently visited the store because she was experiencing an issue with her Samsung phone. From the moment we walked in, Brandon greeted us right away with a warm and welcoming attitude. His professionalism and willingness to help were immediately evident. Brandon took the time to listen carefully to the issue and worked patiently to resolve it. Throughout the entire process, he maintained a positive demeanor and ensured that we felt comfortable and informed. (we were not rushed either) His knowledge, attentiveness, and genuine care for customer satisfaction truly stood out. Employees like Brandon are a great asset to your team and reflect very positively on the company. Because of his excellent service, our experience was both smooth and enjoyable. We extend our sincere appreciation to Brandon for a job well done.

My laptop was dead and I needed a new computer. I'm not a Mac guy (I know, strange that I'd be…read morereviewing MobileMacLA), and was absolutely thrilled with the pc that was built for me. I've had it over a year now without an issue. Fast, SUPER quiet, and no hardware failure. Reliability is my #1 factor when purchasing electronics. Probably the best part of the experience is that they won't try to sell you more computer than you need. Very, VERY good at two things that are hard to find: 1) consultative sales when it comes to computer parts, and 2) research. They didn't just put in any old parts but knew which brands had good reputations and used those components. I attribute the reliability of my system to that kind of attention to detail. If you're a mac or pc person, or both...call MobileMacLA. Ask for Alex. You won't regret it!
