Pros: I find the coverage is great. Very seldom do I not have service or if I don't someone with another provider does. In fact I am usually the one with service. I get excellent help when I need, service has always been excellent, I have never had to be without a phone. If phone is not fixable, they provide you with the same or comparable phone right then. (If you have there warranty coverage)
Workers have always been honest and have always given excellent advice on plans or choice of phones.
Cons: In the past they had a small selection of phones to choose from, but they have improved tremendously.
Summary: I do not see myself changing providers in the near future and when asked about my service/provider I always recommend it. I vacation 2-3 times a year and coverage is always your biggest concern, Centennial has never disappointed me yet. I am also satisfied with the plans they offer and prices. Definitely recommend to others
