 So why would you want this? Well, you can use it in place of your real phone number anywhere where you don't think your real phone number is necessary. So maybe you're signing up for a club card at a grocery store or you're just signing up for, you know, online sweepstakes, whatever. You can use this phone number. So right now it only works with U.S. phone numbers. It's anywhere from three to five dollars a month.
