I am researching home phone options for my Mom. She recently moved in with me (until she decides what to do with her home) and is old-school and wants a home phone line in addition to her mobile phone. I haven't had a landline in years, but to accommodate her, I am willing to get one set up. Does anyone have any experience with the ATT Wireless Home Phone thingy for $20 a month? I am reading some reviews on it, sounds simple enough, but would like input from my Vegas folks if any. TIA!
