Of course, we've been with US Cellular for years, so contract of no contract shouldn't really matter. It does, though. It means they will work to keep customers by providing the best coverage and customer service and not because they're tied to a contract.
Another thing - I can save 5% on my bill every month just by signing up for automatic payments with my checking account and paperless billing. I'm definitely signing up for that!
