I understand most people are doing away with their "land lines" or house phones, as you say and going completely to the cell phones, or I phones. I know you don't like to talk with A. T & T by phone, Barb, but do as I did the other day, drop into one of the AT&T phone stores (we have them on practically every corner here) and a very nice person will explain "everything" about the phone, especially the $49.99 deal they are advertising. They will give you a printed brochure, and you can make notes as the salesperson goes along, so it is much better than calling AT&T. BTW, they have never correctly explained charges to me regarding my land line when I changed service for any reason. LOL
My daughter got rid of her land line, and uses only her Blackberry, which has phone, camera, texting, data, GPS and I don't know what-all. Her Blackberry is through the Sprint phone company, and although her bill originally sounded high to me, my AT&T with phone & internet service is sometimes higher than hers, and I don't use more than $10 a month long distance, if that. Good luck people, there is just so much out there now "to have and to hold"... LOL. (Don't forget all those lovely "taxes" on all the phone services, local, state, U.S. lots of little extras you have to pay for. But don't ever sign up for an extra long commitment, you can usually talk them down if they really want to sell you a phone!
