Sprint Store at 2843 East Grand River Avenue #130, East Lansing, Michigan.

A family member of mine had given me a basically new iPhone 6 after they upgraded to the 7. We were not sure if the phone could be put on my network, as it's previous owner was using the Verizon carrier. I had taken the phone to two Sprint stores—one in Clarkston, MI, where the staff told me I would need a new SIM card but they didn't have one in stock. They directed me to their "Repair Center" stores, which are located across the state. I had business in Detroit, so I then chose to go to that Sprint store. In Detroit, their staff were not only incredibly rude, but also lied to me and were massively unhelpful—even going as far to tell me that it was a lost cause because the phone was not mine anyway. I waited two months to take the phone to this store because I was feeling so dejected from the Detroit experience. However, this store was AMAZING. The man working, Solomon, greeted us as we walked in and did his best to get through the line of customers before us while he was the only employee working. He was kind, and very quickly fixed up my phone to the Sprint network without blinking, and even continued on to help the friend of mine I'd brought along set up her phone with the Boost Mobile network—something he did not have to do because she's not even a Sprint customer. He helped both of us quickly and with a sense of humor as he also helped with other customers as they came in, and he even gave me a discount on my new SIM card because I made him laugh. I don't think I'll ever go to another Sprint store again.
