RICHARD Reviewed ATT Reviews

I switched to U-verse for my internet. The installation was professional and the technician was very friendly. My speed matches what I was getting with cable and it is $20/month cheaper. Highly recommend for those that are tired of the high prices the cable companies are charging.
