I have a great experience here at Sprint. I came in with a lot of questions and I left with all of the answers I needed. There was only one staff member working when I went in, so I had to wait about 10 minutes.
This location is busy so you may need to wait to see a rep. I have been a Sprint customer for many years. The prices at Sprint are the lowest per month out of all the major carriers and the service quality works great in Vegas.
