verizons 69.00 promotion

I think the way to solve the problem of the second line with the unlimited single line is. to cancel the phone number and sign up for the unlimited minutes. I could then get a burn phone for the wife at 10 cents per minute, I save 30.00 per month. 10 for the second line and 20 for the unlimited minutes. Verizon loses 30.00 per month in revenue.
