I have been thinking about getting a Smart Phone but there is a drawback. Because if I got a Smart Phone I would hate to lose the convenience of having phones in every room of our home --- including the bathrooms. Especially there. Is there any cell phone provider that allows us to keep our home phones on the same number and use the home phone number for our cell phone too? I would like to wind up with a Smart Phone and our land lines all on the same number. Is that possible?
