Bye-bye T-mobile

I like the plan. 5 dollars more expensive than VZW. I don't want to stay with T-mobile or VZW congested networks in my area. I like that it is truly unlimited Canada, not chunky 500 mB.
I had old Att UDPs 4 lines and switched after the price increase and expensive Canada/Mexico roaming.
I just have just two question:
1. still have promo 35 dollars DirectTVNow, are they going to drop the price to 10 dollars or not?
2. On what amout can I have FAN discount?
3. Can I use BoGo on iphones 7 ?
P.S. No more Philippines call center. I cannot believe it.
