Carlos, Jaime and Johnnie are fantastic. The staff are efficient and very knowledgeable. Carlos was like a doctor in fixing my wife's phone. Of all the the T-Mobile stores we visited this store has a positive vibe and welcoming atmosphere. View on Google

Everyone wants a new phone but nobody really loves the process of getting one — am I right? Well, let me tell you, Julie and Carlos C. at T-Mobile Grossmont completely change that experience. Whether you're looking to upgrade, switch over to T-Mobile, or you're already a customer who needs some help, these are your people. We came in with a pretty stressful situation. We had gotten our new iPhone 17s somewhere else (clearly should have just come here first) and ran into some issues that needed to get sorted out. They took care of us — effortlessly, no questions asked, smiles on their faces the whole time, and honestly kept us laughing the entire visit. Julie is beyond sweet and absolutely hilarious. Carlos is kind and very knowledgeable. Together they are just the most customer-centric duo — and honestly, that's what makes the whole store feel different. We were there for a bit and I watched them with every other customer. Everyone was walking out with a smile. Every single one. If you're looking to upgrade, get a new phone, switch to T-Mobile, go see Julie and Carlos C. at T-Mobile Grossmont (the location next to the Guitar Center—not the mall)! View on Google

Johnny & Carlos are true MVPs! They managed to correct multiple issues for my wife's account that nobody else was willing to. We were regretting switching her to T-MOBILE & battled for literal months trying to get a solution only to be met with another issue, lies, misinformation, & numerous delays. We went into this location as a last attempt to try & resolve everything not expecting any results, but they not only went out of their way to get our issues resolved, they fixed everything same day. We walked out completely satisfied with the outcome! Johnny & Carlos, thank you for going the extra mile for us & the professionalism both of you demonstrated with two fed-up customers. Both of you are solely responsible for retaining us as customers. View on Google
