Came to post this, beat me by a minute (while I was searching for an old T-Mobile connect thread to revive). 
Note taxes are not included.
Prediction of plan price drops on T-Mobile MVNOs -
There is Boost Mobile 100.00 per year plan that comes with U T&T 1Gb. per month
True, but prepaid for a yr. vs. postpaid by the mo. This may suit a person who only wants the line for a mo. or 3.
Also on T-mobile network - If you or a friend/relative happen to live in an area served by Optimum/Altice/Suddenlink you can get 12 mo. unlimited/unlimited/1GB (fast softcap speed) for $20.
