Since you are working with an agent / person, everything is YMMV. My $10 DCC was waived and the agent didn't care that I have 2+ free lines already. First step is to check your T-life app to see if you qualify.
Main thread on T-mobile subreddit. [reddit.com] Refer to it for more / current info. Some redditors have complained that some agents declined them because they had 2+ free lines already. Some redditors have success trying again on 833-579-2248, 611, chat, or T-Force. Since there is a bit of YMMV with the agent, be kind and nice, and try again somewhere else if you get rejected. Of course, some redditors are trying to get the free line even though their T-life doesn't show the offer (huge YMMV).
Yes, T-mobile did another round of price hikes today for existing plans. Check your text messages of your primary line to see if you will be affected starting April 2nd.
If you don't see the offer on your T-Life app homepage but you see offers like 25% off accessories, save $100 on Harman, SyncUp Drive, etc., try pulling down on the app to refresh the page / offers. If you have multiple lines, try looking on the other lines. The free line offer was only found on one of my lines (main line) T-Life app.
Even without the free line offer, you can still try your luck through 611, chat, or T-Force. Though you run the risk of the system not applying the free line promotion even if the agent agrees to add it.

Found some more info on promo ID250259 from my account data on T-mobile.com. There is more info available, but not really useful to anyone without T-mobile VPN access or code dictionary.
Name: Line Discount ID250259
Start Date: 2025-03-13
End Date: 2025-03-26 (Old)
End Date: 2025-03-31 (Old)
End Date: 2025-04-10 (New)
Initiation Date: 2025-03-17
So this promotion ends on the 26th (Now 10th). T-mobile also tracks the promotion initiation date, which was the 17th for me (date that the line was created, several days after I ordered the physical SIM).
If you are getting this promotion close to the end date 26th (Now 31st), order with ESIM activation. With physical SIM, you are risking your promotion initiation date starting after the promotion end date. Not sure if the system cares, but it tracks the dates so why risk it. You can always convert your ESIM to physical SIM later.

I just wanted to pop in and give an update.
Magenta Max 2 paid, 1 free, 1 digits, Home Internet.
Tile for free line appeared in T-Life app.
Instead of calling or chatting, added new BYOD via T-Life, physical sim.
$0 out of pocket, SIM arrived today. Put it in a spare unlocked iPhone 6S Plus.
Viewing Account > Cost Summary on T-Mobile website via web browser I see "$30 Line Discount ID250259 (Additional Lines)" Nice!
Now I have Magenta Max 2 paid, 2 free, 1 digits, Home Internet.
Credit goes to the posters who mentioned T-Force Reps said to add the BYOD line in the app yourself which sidesteps fees and activation charges while triggering the discount automatically. It worked for me.
Hope this helps someone like me who doesn't care to call or chat with T-Mobile.

The rep mentioned that you could add the line yourself through the t-life/t-mobile app and as long as your account is eligible, the line discount will get applied automatically so you could possibly just add it yourself but ymmv for sure!
But I never got a text saying the line was enrolled in the line discount ID250259 and I don't see it on the website either under promotions ( https://www.t-mobile.com/account/promotions ).
I called to verify and am now being told I didn't qualify - and now going to have to cancel the new line. The rep says because of this I won't qualify for any promotions for the next 90 days - which is total BS because I wouldn't have added the line if the rep said it wouldn't be free. I only had the line added for a few hours!
Just sharing because if you got the line added and don't see the promotion - you might have to call and reverse the changes.
EDIT: If you're unsure about the free line and whether you qualify, don't use an eSIM to activate - use a physical SIM - the reason is eSIM activates right away and if you activate it, you can't cancel the line until the end of your billing cycle, which for me is a month from now. While Customer Care did credit me back the $45 it will cost to add the line for 1 month and the $10 activation fee, it also means I am banned from any promotions for 90 days from the end of this billing cycle, really it ends up being almost 120 days. If you use a physical sim and don't activate the line, they can fully reverse everything.
Since some have reported success, I might try to HUCA a time or two, though I also don't want to chance that a rep manages to screw up my existing discounts since right now I have six free lines and the 20% off "Insider Hookup" of a couple of years ago, so I'm getting an outrageous deal already. Still wouldn't mind another free line if I could get it, but don't want to push too hard and screw up a good thing.
i would wait 1 billing cycle, to make sure your new free line shows up as FREE.
then cancel one of your paid line, AFTER ONE YEAR.
each account much have a minimum of 2 paid lines, or else, you have to pay for all of your free lines.
you cannot add new free voice lines, if you cancel a voice line in the past 90 days.
if you canceled a voice line, more than 90 days ago, then you can add the free voice line.
1. so if i port out today then no free line?
2. best is:
add the free line today. then in ~May 2026. port out a paid line to att for example. and then port back in over to free line?
I did receive a text saying congratulating me on my new line and discount ID250259 with a link to a promo website for my plan. I saw the new number and this discount ID. The text took about 3 hours to arrive after speaking with the rep.

I'd be screwed if I had to pay for all those free lines that are in use! Hoping TMo can fix this, even if I have to give up the free line I just got.
Argh!!
so is decreasing the voice lines
