T-Mobile is giving away free lines with (almost) no catches to make up for its imminent price hike [Updated]

Update:
The new free line deal detailed below is very much real and very much live already, at least according to the always well-informed folks over at The Mobile Report and several lucky Redditors who've managed to get in touch with knowledgeable customer care reps after a few failed attempts.
As suspected, this is indeed a "targeted" offer, which means that you can't really ask for it if you don't see a notification in your T-Life app and not everyone impacted by T-Mo's impending price hike is also eligible for an additional line of service at no extra cost. On the bright side, you're not looking at a BOGO (buy-one-get-one) affair here, so if you qualify for the deal, you don't have to add a paid line to your existing account to score a second one for free.
Because nothing in life is truly free, you shouldn't be surprised to hear that T-Mobile will charge you a one-time $10 "Device Connection" fee for your complimentary line, which is really not that bad. What's also great about the new promotion is that users with multiple free lines on their accounts already are apparently more than welcomed to get yet another free line, and ironically, even some customers who are seemingly not impacted by the latest price hike are seeing the deal in T-Life. Too bad the whole process is so random...
The original story follows below:
But this time around, there might be a silver lining. Namely, some T-Mo customers could be eligible for yet another free line promotion. That's at least according to this one Redditor who got up bright and early this fine Thursday morning and went to check their bill in the T-Life app to ensure no price change had occurred.
Instead of that, this lucky user was welcomed by a totally unexpected notification informing them of a free line deal made available "just for being a valued customer." The offer, unsurprisingly marketed as a "limited-time" thing, apparently requires redemption by phone call, which as you can imagine, is a little tricky at the moment.

A couple of other Redditors are claiming they've seen the same promotional banner as the original poster at some point in the last couple of hours, but after refreshing or restarting the T-Life app, all traces of it went away. That seems to suggest perhaps the deal isn't supposed to actually start today to avoid overflooding T-Mobile's already super-busy customer care phone lines.
Then again, if T-Mo does plan to throw free lines at subscribers to offset those imminent rate increases, it would clearly be wiser to do that sooner rather than later. Before getting too excited, you may want to consider the possibility that this promo will be a targeted affair offered only to certain customers. So, yes, you might or might not qualify depending entirely on your luck.
Stay tuned for more details (on both this deal and the impending price hike) as we receive them (either officially or unofficially), and if you do happen to see the free line offer in your T-Life app, make sure you take a screenshot and send it our way. You can also call that phone number and try to ask for additional information, but don't expect a happy resolution very soon. T-Mobile has a lot on its plate right now.
