3jam isn’t an altogether new service—it used to be primarily a text messaging service—but its Google Voice-like features are. Like Voice, 3jam rings all your phones from one number, gives you access to your call history and SMS history, offers (visual) voicemail online, and more. Unlike Google Voice, 3jam also supports forwarding your calls to Skype, AOL, or Yahoo Messenger. It also lets you port your current number into 3jam for easy transition—something that’s not (yet) available with Google Voice.
What’s more, 3jam isn’t in an invite-only beta. The catch: 3jam costs, at minimum, $5/month. That’s not terrible considering what they offer, but in light of Google Voice’s free offering, not all that many folks would be that excited at the notion of ponying up cash for 3jam. Then again, if features like Skype or IM ringing are particularly important to you (say you want to save some cell minutes), 3jam may have a leg up on Voice.
On the other hand, 3jam doesn’t currently have all of Google Voices features, like call filtering.
