Does this service block your number though so they don't see your ACTUAL number though? And can you advertise it via social media and such as an easy service to use? I am curious about this too. I will never sell my number though if there is a slight chance they can get a hold of my real number...it's why I stick to KIK really. And it's an easy way, they send tokens/giftcards/etc and I just send them my username. But there are some people who do not have KIK or just aren't tech savvy
