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.

Costco member who has had two lines since Sprint days. Kickstart v2 and Unlimited On Us from 2020. Switched to TI just before merger, so it was $30 total since merger.
Did NOT get a text or email that we were being hit by $5 increase, but when I logged into the account it was there. $5 added to Kickstart line. $5 added to Unlimited On Us line BUT credit for that line increased to $35, thus keeping it free. Bottom line : 2 lines $35.
This weekend I called Costco T-Mobile 833 number. Said I wanted to port in my son's US Mobile number (Verizon network) to the free line deal.
The Costco rep put me on hold for quite a while, 10 minutes or more to talk to a T-Mobile rep.
She came back and said we can't add Kickstart lines, but the T-Mobile rep told me that I can add it as a standard line and then when we're all done, they can help change the SOC code on their end to Kickstart.
I was told that porting in a new line to account gets me a $75 Costco shop card, but no VISA card, those are only for port in of a postpaid line from a T-Mobile competitor. MVNO and Prepaid do not qualify.
She went ahead and created a new account with a temporary number. She pushed the number via eSIM (our preference), then ported our old number onto that line. Took maybe 10 minutes for the port to show up while she did other things. When she was done she got the T-Mobile customer service rep back on the line and they changed the SOC on the back end.
Whole call took a little over one hour, and now I have 1 paid line and 2 free lines for a total of $35 a month.
Can't beat it.
This despite pushing this offer to me in TLife and TWO agents telling me I qualified. Chatted with T Force now to see if there's anything they can do for me besides cancelling the line. Can't lose my ported number.

Line Discount ID180002-FREE with 2 paid lines? I think?
Line Discount ID200006-free
I'm not 100% sure but I think these are what the line discount codes are based off of internet searches. I think I'm basically paying for 3 lines and 6 are free? I got the free line offer a few days ago so I was thinking of getting it (I'd be at 10 lines) and then I can cancel my 2 lines that are bogo in January so I will be back at only 2 paid lines. Would that work?
The SOC code isn't automatic. I have a 9 line plan (TIULMF9), and the 9th line (a free line from 2021) doesn't have kickback.
However, when I added two lines (which I ported out to Total during their byebye deal), the rep added kickback to those lines when I asked (for shits and giggles), and they did appear in the bill. However, most reps in general won't do it for me.
I just added the 10th line...these free line are great for reducing the bill by $10 each ...
1. I'm currently at magenta 1.0 with 3 paid + 5 free lines and total cost is $112 with insider hook up and autopay. It looks like if I jump on this deal even if the line isn't free I'll pay less because I'll move from 8 line $20/line credit to 9 line $30/line credit which will come out to $100 credit vs $150 credit?
2. Did anyone add line through the app and get the deal applied automatically?
Currently Magenta 55+ plan and I'm paying $88.50 with autopay

What's the census.. are most getting it anyway by calling messaging and just asking or not worth the risk of some rep screwing things up? I get very leary nowadays.
Unfortunately, my bill will be going up $20 for the 4 paid lines.
