This is an off-contract pre-paid plan. I believe that you must buy these as SIM kits from Walmart. When I got it, you had to buy it from a physical store, but it looks like you can do it online now though it may take some time for your SIM card to arrive.

Word to the wise, you get basically no T-Mobile customer service once you switch to pre-paid. I have been on contract with them before and they are very helpful, but on pre-paid it seems like you are on your own.

It's not pre-paid only. You can get it month to month if you buy the SIM starter kit and activate online. You can't get it in T-Mo stores.
