Umm woah, I have simple choice too. Any more info??
For me to pay only $10/mo, the agent said I would have to switch to T mobile One plan.
If I switch I will be giving up my HD video streaming and LTE tethering.
For both plans, the monthly cost will be about the same for me before adding the watch.
Currently, I pay $200 + $50 tax each month for 8 lines (not including phone payments).
After I switch I will be paying $240 taxes included. (Everyone in my family uses over 2gb/mo so no $10 discount applies.)
So it will be $10 less before adding the watch ($250 -> $240) But all 8 people will never see HD streaming videos again on our phones. I use LTE tethering frequently for my iMac and iPad at home.
My plan now is to preorder a LTE AW3 and wifi AW3 tonight.
Use the LTE AW3 for a week and see how it works out with my daily life.
If I like it, I switch to T mobile One plan. (I am the main account holder so the 7 other members will have to just deal with it.)
If the LTE AW3 turns out to be not very practical because of short battery life or some unknown reason, I return it to apple and keep the wifi AW3. And keep the current plan.
