Jonathas was one of the most helpful people I have ever come across when it came switching carriers. I love shopping at Costco, and a really needed information about a new plan, and need to switch phone carriers, and I knew I wanted to switch to T-Mobile, so when I learned that I could do this at Cosco.I decided to see for myself. From start to finish, my experience was pleasant and the service was excellent. The big reason I wanted to do this at Cosco is because Cosco members seem to get exclusive deals that not available in a regular T-Mobile store or over the phone. Plus on top of this it's extremely convenient. It is literally a one stop shop. I highly recommend visiting this store to anyone who is looking to switch to T-Mobile. View on Google
