I have a 6S with Verizon - completely paid off. Ultimately I hope to trade in that phone to get a credit from Verizon that will eventually be applied to my monthly statements. I was told (by a Verizon rep) that I should purchase the iPhone X first and worry about trading in my 6S later. I'm not interested in the trade-in promo Verizon is offering for the iPhone X (too many conditions). I plan on using the Verizon app or website (not apple's site) to purchase. My question is - can I proceed with immediately purchasing the iPhone X, or do I (should I?) click on "upgrade now" and go thru that process. I don't want to change my plan, etc, etc. I feel if I go thru the "upgrade now" it will take longer than if I just go directly to purchasing the phone and worry about what to do with my old device later. Thanks!
