A decade ago, your mobile phone number may not have meant much. In the days before number porting, mobile phone numbers were transient. If you switched carriers or moved, you got a new number.

Things are a bit different today. You can take your number with you from one mobile carrier to another, you can port it VOIP services like Vonage, or forwarding services like Google Voice, and you can even port it to a landline phone. Your phone number, much like your personal email address or Twitter account, belongs to you for as long as you want to keep it.
