I want to thank the team at Costco Pacoima. I came with Judith to get our upgrades and everything was smooth. Returned with Dalia and Crystal, they took care of transferring everything for us. It’s truly a team effort. You can count on this team to get it done and provide such great service! View on Google

I came in to the kiosk and was first helped and ordered my phone with Judith. She was so pleasant and informative. I felt comfortable and like I could trust her. Amazing service. Then when I came back to set up my phones, I was helped just as amazing by crystal and Dalia. They were very patient and friendly. I prefer this team over most T-Mobile stores just because of the attention and genuine care they give us. If you want a reliable trustworthy team and service come see the team in Pacoima Costco. Thank you guys! View on Google

I had an outstanding experience at the T-Mobile kiosk inside the Costco in Pacoima. From start to finish, the service was exceptional and exceeded my expectations. My sales representative, Dalia, was absolutely amazing. She was incredibly knowledgeable, patient, and genuinely helpful throughout the entire process. She took the time to clearly explain the different plans and options available, making sure I fully understood what would work best for my needs. I never felt rushed or pressured—just well-informed and supported. Dalia helped me get a great phone, and I left feeling confident that I made the right choice. Her professionalism, positive attitude, and straight-to-the-point communication made the entire experience smooth and stress-free. I also want to highlight the overall energy and teamwork of the staff at this location. Everyone was friendly, professional, and welcoming, which really added to the great atmosphere. If you’re considering switching to T-Mobile or upgrading your phone, I highly recommend visiting the Costco Pacoima location and asking for Dalia! You won’t be disappointed View on Google
