I've had a military business plan with T Mobile for well over 10 years and recently moved my business to a new state which required me to create a new military business account and move everything over. Anthony helped start rhe process and Jackie picked it up a few days later when we ran into some issues. To be clear, the issues were not with the location, they were with the T Mobile business side of customer service. I am beyond well aware that even the members you run into in the T Mobile location only have so much access, so they'll have to call customer care too, but often time their expertise can help customer care with their job. Why T Mobile? I've personally lived in 4 different countries on 2 continents, and traveled to many, many more and T Mobile works every where I need it to. The internet is fast, it's reliable and when ever I'm state side the reps in store are great. The business side of the app needs help, and customer service jobs seem to be farmed out to the Philippines which is fine, but sometimes they need some guidance with specifics. Hence why I come into the store. Extra shout out to Jackie for sitting on the phone with customer care and really advocating for them to take our issue seriously rather than just telling us to wait more and see if the system works itself out. Which (spoiler alert) it won't. All in all, this location is awesome. Sometimes you have to wait as they dont staff a million people, but the employees they've got are first class. Give Jackie and Anthony promotions. View on Google

I had an amazing experience with Dylan at the T-Mobile store in San Marcos . He made switching from AT&T to T-Mobile incredibly easy, quick, and stress-free. Dylan really listened to my needs, recommended a fantastic plan, and got my device switched over in no time. I’m so happy with the service, and I can’t thank him enough!” View on Google
