Only for those on a post-paid plan. I'm on a pre-paid plan that they'll have to pry out of my cold, dead fingers ($30/month, unlimited data+text) which doesn't receive it, unfortunately.
Well, after posting that comment I decided to check out their current offerings which led me to discover Mint Mobile. It's an all-around better deal, provided you don't mind paying for a year up-front. I think I just may switch next month!
