This is almost cheap enough to pay for the new device I would need to use it. I could save ~$25 a month given my current usage patterns over the T-Mobile plan I have. I imagine users of Verizon or AT&T, which are quite a bit more expensive for the same amount of data, might consider this a huge bargain. Certainly being able to migrate across two decent networks makes it more likely to be competitive with the better/bigger networks of Verizon and AT&T. I wonder, and can't seem to find in my cursory glance through the FAQ, how this handles regular numbers vs Google Voice numbers. I currently use two numbers on my phone. My Google Voice number (which is how I assume this thing does what it does), and the "native" cell number I've had for nearly 20 years. I know I could port the native number to Google Voice, but I currently use both numbers...so, that wouldn't really work, as I'd still need to be able to use my Google Voice number, too. It's a little clumsy on current Android phones (you choose which number to use for outgoing calls either at call-time or by-default), but it works. If this only works for Google Voice service, it might be a bit challenging to switch. Also, they say this supports MMS. Does that mean sending MMS is finally coming to Google Voice?
