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.

Base price for 9 lines of Magenta Max is $370 after price increase. Each free line yields you $35 in credits. So if the newly added line is not free then you will still have 5 free lines which yield you a discount of $175. Additionally, your Insider will give you another $74 for a grand total of $121. If the newly added line is in fact free (and the billing system will do this automatically, no need to ask agent for a free line) then you'd be looking at 6 free lines. Math here would be $370 - $210 (free lines) - $74 (Insider) = $86.
So you see, it doesn't really matter if the next line is free or not. You'd still be saving money. If the newly added line is free you will receive a text message congratulating you on promotion ID250259.
Had to switch to that from Magenta Military plan, and had to cancel my 3rd voice line due to $15 monthly increase on my 3 voice line. I was paying the same $102 for 3 voice and one watch line.
The first two reps (over chat on T-Life), they were by the book, and I wasn't qualified since I opened two lines already outside 14 days.
The last rep, he was able to give me a free line, but he worked around it. He said he needs to open a BYOD line, then apply a discount on that line, so at the end of the day it's free service line. I received this promotion back in 2023, and they have set it up like this as well.
So don't give up, if they're going by the book! I been with T-Mobile for over a decade, so they valued that and made a special deal for me.

I am on the old One Plan with plus, hookup, and 4 paid and 5 free lines. Didn't get anything in the app for the main line about adding another "free line."
Would adding another line also lower the bill like you stated with the newer plan?
Unfortunately, I did get the text about the $5 line increase.
Worth the risk of calling or chat via app to try to add the line? We all know reps are basically useless and will say anything. Best way to go about it? Call and ask if the promo shows on my segment?
