You can port an active number away from NumberBarn or NumberGarage regardless of the plan you're on.
The plan for a number does not in any way dictate the ability to port away. Porting away is available with all plans! And it's important to note that the NumberBarn Port Away and Park plans are the same price.
You do not need to make any changes to your active number if you want to port it away.
