Can't replicate it for me.

You can do it from a computer as well.

Sign into TMO
Click on the plan total cost right under "Plan" (for me its Magenta. . . . . .$96>) just above 1st Line # on Account page.
Click on Manage my Plan on next page.
Choose whatever on the right column that will be an upgrade for you and hit "select Plan"

On next page--the review charges page--hit the right arrow to the right of "Add-ons"

It will show you 2020 LOU 3, and 4, etc. under the appropriate phone line #'s. Here's what my page looks like as far as LOU3 and LOU 4 on the "upgrade to Magenta Plus" page:

The promotion trade in iPhone XS for $830 does not stack with the free line. You will get your $830 and lose the free line. You will have a paid line paying $20 a month.
Thank you for your comments. I was told $5 for the new line. Isn't it true? Where does the $20 comes from? I thought to add a $5 line (no data) and have it dormant until I am eligible to cancel the line. Will be using the new iphone 12 with old sim(number) though.
Will this work?

I did the same thing as you today at Costco. Did they give you a SIM card or the SIM card is in the phone? Thanks.
I don't know if the sim was in the box or not, the rep opened the box inserted the sim and set up the service for me, so not sure if the sim was from the sealed box , or the rep provided the sim from the kiosk. Does this make any difference at all?

Hi,
Thanks for the input. I have Magenta plan, added a free line in Nov and one free line this time, so total have 6 lines, paying $ 96 with 20% hookup discount, after adding the December line, didn't see price change, but the LOU 3 doubled, instead of LOU 4, should I do this trick to trigger the LOU 4? or in my case , just leave it untouched ? Thanks.

Thanks, that's interesting. I do see LOU 4 on the new line, but none of the other LOU 1,2,3 are showing up on any lines. I think they are on my account level.

Long story short, The rep had to change my plan to magenta to get 9th line (without my consent) and I asked another to switch back. I don't think those LOU promo were applied to specific lines. Which allowed me to stack couple free phone promo to LOU2 and LOU3.

The trick "change plan" is to display "Line on us 4". this is for people who are already see double "line on us 3".

If you don't have double "Line on us 3", this trick is useless. This trick is for display only purposes. No changes are actually made.

This trick only works on latest plans like Magenta, magenta plus, essentials.

I didn't actually upgrade, so on Account page it still shows FLOU3 X 2 discounted.
I wasn't trying to trigger it onto the account, which yes would require actually upgrading (if this falls in line with those who did the add more data/downgrade the more data on grandfathered plans mentioned earlier in this thread. . .so as to see it on account page. I just wanted proof that LOU4 did exist, and on my account at some level. And the screenshot of it. If it doesn't show up on my account in the next few weeks I will chat in for a credit.

TBH, it's only $16 more for me to upgrade to Magenta Plus on 7 lines so I'll probably do that anyways. . .just got scared off by the iOS App method of clicking on "Plans" at the last step instead of my method of clicking on "Add ons" at the last stage, and this is what it says:

Plan change—items will be removed
Magenta®

Insider Discount

I don't think the Hookup will be removed by upgrading to MPlus from Magenta, but just seeing that makes me want to do an upgrade through T-Force instead of online, and not just to see FLOU4 on my account page.

I have Tmo One and this is the first time I'm seeing LOU4. I don't have double LOU3 just an $6 insider discount. Seeing LOU4 for the first time on the new line even just for display makes me feel better as the rep keep saying it's on my account, but it has been a ghost.

I have a TMobile One plan with 7 paid lines and added new free line in Nov 2020(now total 8). I was told by costco rep that I can add a new line and get $100 byod discount. If I add a new line on us, will my plan be changed to a different one(Magenta/MPlus) or is there a way to increase the lines to a max of 12 lines on TMOBILE One plan?
