Pros: Great Signal Coverage just about everywhere and good Customer Service.
Cons: Three Year Contract, Minutes don't roll over
Summary: After having several years of good service with Centennial I decided to switch to AT&T/Singular. They had this great phone with the features I wanted and more minutes which would roll over. After getting my new phones I learned that they would not work in my home. I had to go out side to get any signal. After talking to AT&T technical support I learned that their coverage in my area was marginal and this was the best I could expect. Well, I canceled the AT&T contract and Centennial ported my numbers back, no questions asked. The Centennial customer service was great. I don't have the phone I wanted but I have great coverage. We just took a trip to Alaska and Centennial had full coverage in most places.
