You can only sign up for the Even More Plus plans (contract-free plans) by walking into an official t-mobile store. They used to offer it on their website as a nice choice, but they removed to reduce confusion, but probably really to increase contracts. Furthermore, if you walk into the store, they also have an extended payment plan for your phone, thus you can get a Contract Free plan, which will save you $20 a month, for example Even More Plus 500 (Unlimited Data, Unlimited Text, Nights, Weekends, and 500 minutes) for $59.99 (equiv contract plan is $79.99) a month. Then they have an extended payment plan for your phone where you can pay $20 a month with 0% interest and no fees until your phone is paid off, thus giving the best of both worlds, no contract, no big upfront costs for phone, and once your phone is paid off you don't have that added cost per month. Really excellent and saves you around $400 - $1000 versus a contract.
