U.S Cellular Customer Reviews

 by john on U.S Cellular

I've been with US Cellular for almost 20 yrs. Until recently they have always stood to their word with conversations concerning my monthly rates. I have reduced the number of lines, and it seems as though they have an amount they want to charge me monthly, and my bill is going to stay the same regardless of any changes. My service is horrible. and I have a problem dropping calls. As soon as my overpriced phone finally gets paid for, my ability to call gets worse. I have a couple more payments on my phone, and when its paid for, I'm changing carriers !
