Existing customers being those with active lines and plans already...can bring a line from another carrier.
Some promos are only good for new customers with no lines.
Hey there and thanks for posting.
For that promo, you will need to port in a number to take advantage of the offer. I'm sure T-Mobile will run more cool offers in the future, so I suggest just keeping an eye on our website going forward in case something else peaks your interest.
Thanks for posting.
