I initially parked my number, waiting for activation when the business begins.
It was really simple to do, and pay (Via PayPal).
I had a problem uploading my message, and after I sent a question, answers were immediate, and easy to do.
As well, live help is available, that helped me out, when I uploaded the wrong version of my message (Duhhhh...)
I think its a excellent, well thought out service.
