Its $20 for the first year so you really cant go too wrong with this. I love mine. I signed up for two years when I got mine. After hearing a few reviews on the local news and I believe one on CNN as well and doing a little homework I just couldnt see where you could go terribly wrong.

The number is completely portable, all you would have to do is submit new address information if you should ever move. And if you wanted to totally change your phone number I believe its just $10 to do that.
