Well looked at everything I can about the iPhone 7 not seen anywhere it mentions Live Photos. Will this phone do them? I'm guessing yes as the last 2/3 phones have 6s, 6s plus and se. Seems there has been some improvements live 7mp front camera and duel back camera only time will tell how much better they are. The 7 is also meant to be faster than 6s something they do keep improving on til now 6s been fastest even when se came out. The better battery life on 7 has to be one of best improvements. Water proof phone another good thing even if it only for sake of being able to test it without ruining warrentee on it. I know 6s supposed to be able to work after being in water but not tried it incase it does damage it.
I had a quick look, Think it's extra for yearly.Somewhere l have his private hotline number maybe you should give him a call.
Have you thought about the monthly plan system that they mentioned at the end? I'm not sure how it works but if you change your iPhone yearly and your happy with your data company it might be an idea.
