This will surprise you...
My 78 year old mother-in-law made a 43-minute phone call from Denver to Loveland (yea, that's an in-state call) and MCI charged her $60 for the call because she doesn't have an official long distance carrier allocated to her CenturyLink account.
My mother in law for ions and ions has used a "long distance calling card" for MCI when she has the need to make a long distance call. Yea, that's going w-a-y back to the old Ma Bell phone company days. But hey, she's 78. She doesn't believe in big phone contracts and bills. Plus she doesn't really call anyone long distance. :)
Truth be told - MCI has these "laggard" types of consumers, and they're apparently keeping MCI in business. That doesn't seem fair to me that the elderly, who don't want the fancy new bells and whistles of smartphones and all you can eat data plans, have to pay the piper such a hefty fee. The call was made from my mother-in-law's home, but she didn't let her fingers do the walking, a house guest did. Everyone assumes calls are 'free' - particularly local calls.
Enough with my rant. I just don't like seeing MCI getting away with a $60 in-state call fee. That's insane.
