Sort of. There's no early termination fee, so in that way it's better than legacy carriers. But you can't take your RW phone and use it on any other network, so you are out the cost of the device.

I believe you have to buy the SIM card and then go to this page to pick your plan:
I literally just did this, so the timing of this post is nice. Even more nice is that they are waiving the $10 SIM card fee right now.
You buy the actual plan after you get the SIM and activate it. I don't know what they charge for activation, if at all.
Then you can use your unlimited data for calls (if I'm not mistaken)
It's possible to tether anyway, but YMMV - it's through workarounds like using only HTTPS, setting up a VPN, or changing your desktop user agent.
