My son has three lines on his VZN account. Line 1 - iPhone 6 -unlimited data (his) Line 2 - iPhone 4 - 2 gb plan (wife) Line 3 - dumb phone He would like to get his wife a new iPhone. I believe the dumb phone line and his line are the only ones with usable upgrade. If memory serves, he used his wife's upgrade to get his iPhone 6. He would like to retain unlimited on his line. What is the best way to get a new phone for his wife? If he uses line 3 upgrade and gives that phone to wife does he add an extra $20 a month for data he won't ever use ? What about Edge program? Does that make phone more expensive? I think he should know all possible options before going into VZN store since I don't trust the sales people to give the whole story. Thanks for suggestions.
