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.

If you tap the See Full Terms in the T-Life app, it clearly states " Free new line for qualifying existing accounts with 2+ voice lines on a family plan and a max of 2 current free lines"
With monthly bill credits. Subject to change.

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.

Thanks for the replies earlier regarding my adding the 9th lines with the Magenta 1.0 plan with rep unenrolling the lines promo. Now I just received sim card they sent me, will activate the sim. Also I checked the promotion on the 8 lines I have and saw the new added lines had correct promo attached. the other 8 lines all have their own promo, do you think I am so far there's nothing to worry about? because I was worried that the rep messed up with the original lines promo and inside code when adding the 9th line? Thanks so very much as always. Have a wonderful weekend!

Your phone and plan details are below:
Phone: BYOD 3in1 SIM Card
Plan: Magenta (2 line)
Does Magenta (2 line) just means my original 2 line plan or does it mean it added 2 lines? Although there's only one new phone number on the account for the SIM card. But when I go to cost details it's now $155 instead of $120. A few days ago it estimated $180.
I had 4 free lines before and now 5th.

Previously I had 1 x Kickstart, 1x TI on US, 2 x Home Internet.
March 14 - see promo on app and call. 45 Minutes later I am assured that all is good and SIM is shipped. Charged $10.
10 minutes after call TI on US switched to Kickstart. Now two Kickstart lines show as $40 each. Previously my only line was $25.
March 17 - SIM ships, no new line showing in account.
March 19 - SIM arrives. still no line. SIM connects but doesn't activate a number.
March 21 - Another 45 minute call. My original lines are still screwed up and the new "free" line showing as Go5G Plus. Was assured that all promos will be added in a day or two and all will be resolved within a billing cycle.
Will give them a chance but I am frustrated to the point where I might just close all lines and go somewhere else. Every single transaction with them has been a nightmare...
Bottom line - do it all at your own risk and if you have some random old legacy plan prepare for a bunch of complications.
Just to add - my account does have a banner stating that it has pending plan changes. I will keep updating in case somebody is in a similar boat.

Edit: to clarify, on a 2-8 line plan each line above 2 is an AAL (add a line). On a 9 line plan every line 10 and up is AAL and not eligible for KB.
My current promos:

Line Discount ID200008

Line Discount ID220005
Line Discount ID250259 (This is the brand new one)
and hopefully the insider discount

I was able to figure out my SOC, which is TIULFM9 .
Looking at my last bill, I see my promotions as
ID180002; ID200008; ID 200011; ID200012; ID200014 and ID200055.
All of these show a credit of $30 per line. I have 9 lines before adding the new one, so I have maxed out the $40 for autopayment credit.
My account does show the new line, so I have 10 lines (plus internet).
I received a text confirming that the new line has the ID250259 promotion attached.
So even before adding this line, the credit for the free lines stayed at $30. My next bill will not generate until early next month, so I will see if anything changes.

Missed those earlier ones I guess.
Found a comment buried in a reddit thread from what seemed like a rep. Boiled down to saying they're only offering the new free line on bundled family plans, which I guess my Kickstart lines and other old sprint ones aren't. The thing is, they already migrated my billing to the tax inclusive T-Mobile system so idk.
Getting doubtful this works. No promo on account page. The reps I've chatted with insist they see the segment/ID even though I don't.
New bill expected soon. Doubting it shows a discount.
