I would like add a line and het an IPhone 8. Do I need a contract or can I use the edge program where I pay monthly until the phone is paid. I also would like to get the iPhone X when available. Please advice. Thank you!

First and foremost, unless you are technologically inept I'm not sure why anyone would opt for an I phone over an android system! The android is a much more superior os, and device in both diversity and functionality.(always playing catch up to Samsung) if you want to broaden your horizon buy a note 8! I have one and I have to say, Samsung more than made up for the note 7 debacle. But yes, as Rob stated there are no more contacts, only outright purchases, or monthly device payments

They dont do contracts anymore. They only do monthly payments or if you buy the phone outright which would cost so much more.

I apologize I have not been educated on payments and nobody had told me anything about an edge program existing.
