Starting December 20th customers on an eligible plan with at least 2 paid lines can add a line for free.


Eligible SOC list: https://i.imgur.com/LZegl3r.jpg

Please note: There's a lot of misinformation and confusion around this promo. Inevitable when a promo like this happens half a month after an identical one just ended. Here are some critical nuggets of info:
  • The promo is called "2020 Line On Us 4"
  • It is fully stackable with "2020 Line On Us 3"
  • Internal docs mention a scenario where it isn't stackable. It is referring to "third line free" promos and only to accounts opened on the 20th or later. This appears to be causing confusion.
  • The promo seems to be showing on accounts as line on us 3 (double if you already had it). It's a known issue and being worked on. Will not affect eligibility.

Offer now available. Some reps are not yet aware of the promo's existence, so please be patient with them. You can also add the line as normal online and the promo will automatically apply within a bill cycle.

Ineligible stackable promos:
  • iPhone 12 "on us" (2020 Apple Trade Activate P3)
  • BOGO iPhone (2020 Apple Buy 2 P11)
  • Free Galaxy A71 5G with new line (2020 Samsung Activate P12)
  • Free OnePlus 8/8T+ 5G with new line (2020 OnePlus Activate P5)
  • Costco BYOD promos
  • TFB-exclusive promos

If your promo isn't working under your account properly try this (worked for me):
https://slickdeals.net/forums/showpost.php?p=143239985&postcount=899


Still on TMO ONE All In Promo plan (FRLTUL2LP) which is never eligible for free lines?

This is a great (grandfathered) plan as it gives you 2 lines for $100 or $80 after 2GB data limit kickback on the 2 lines (or even less if you have the plan with T-Mobile employee hookup code). Plus with the additional promotion you get HD streaming, 10GB full speed hotspot and twice the international data speed (256kbs instead of 128kbs).

BUT... this account only supports 3 lines and unless you got the one free line they offered once under this plan you never got and will never get a free line with the plan.

But if the plan works out for you can move to another T-Mobile One plan (FRLTULF2) which cost a little bit more (2 lines for $120 or $100 after kickbacks) but you will be eligible for the free line and hopefully for additional free lines in the future (the plan supports up to 8 lines in total). The reps are also be able to move the kickback and ONE Plus promotion to the new plan. They might not do it immediately for the new free line but this is also possible and might need another try.
Plus the new plan includes $10.99 Netflix Standard HD account contribution which also needs to be factored in as a bonus.

If you want to get out of that hole and make the change here is my conversation regarding the plan change with T-Force on Twitter:
https://slickdeals.net/f/14713250-t-mobile-customers-add-a-line-for-free-starting-december-20th?p=144023981#post144023981

Then I called 611 at night and asked the overseas team to also add the promo add-ons to new free line so that all lines on the account have the ONE Plus promo (no kickback on the free line of course):
https://slickdeals.net/f/14713250-t-mobile-customers-add-a-line-for-free-starting-december-20th?p=144031265#post144031265

Summary of the process and overview of changes:
https://slickdeals.net/f/14713250-t-mobile-customers-add-a-line-for-free-starting-december-20th?p=144039584#post144039584

As I wrote it needs some time and the right reps to make it happen as I struggled with reps in the past to switch to a different T-Mobile One plan and not ending up with a Magenta plan and losing the kickback and One Plus promotion.
Good luck!

-----------------------------------------------------
Regarding costs to add new line

If you add the line via the website, youll pay $10 for the SIM card to be shipped to you.
If you add the line via a phone call, youll pay the $10 SIM card charge and also $20 for assisted set-up. It is relatively easy to get both of these comped.
If you have a spare sim-card or eSIM, you can use that instead of paying $10 for a new one (bear in mind that it may not be able to do SA 5G). You will need to call since the website does not allow re-use of old cards. (You can also do this via online chat support lines like in-app chat and t-force on twitter)
Expired cards do work, but you have to request a replacement. Again, no SA 5G.
If you have a Costco near you, they will give you the sim card and activate for you for free. You also may get the YMMV $100 cash card (but so far the jury is out if it actually will go through)

Quote from ppatel334 :
Line added on Magenta Plus. Putting me at 6 lines for $112/month w/ Insider Hookup.

I called to do this (611) and asked all the questions:
- Free Line on US promo - eligible and added (promo already reflected on my account)
- Free phones - not eligible
- $100 Port-in Rebate - Expired on Dec 17th.
- I didn't try costco, because I don't have anymore phones. Still waiting on my $200 + $100 from last time.
I think the Costco BYOD for Nov's free line was invalidated, and its not valid this time too. My previous BYOD submission has now vanished from mypromochoice website, no email of decline or anything

Confirmed that "2020 Line On Us 4" works for my very old "Simple Choice North America 6GB Family Match" plan.

I also scored a Free T-Mobile Proxy/Digit Line.

Thanks for sharing the awesome deal.
How did you get a proxy/digits line?

If I cancel an existing line after getting free line, will free line becomes paid line? Or Will it remain free line?

Quote from joeBwonkenobi :
It's not explicitly listed would the pixel 4a 5g 50% off deal stack?

Rep told me no and that no "add a line" offers were eligible because the line is free when I asked about the Pixel offer.

Also (according to my rep) apparently the promotional credits won't apply until after 2 months, then there will be a retroactive $40 credit to cover the cost before the promo kicked in.

I'm on MGAMP2 and was eligible for the LOU2 and this, but was not eligible for LOU3. It was on the eligible SOC list for 2, but not on the list for 3 and now this.

Quote from BOOMGOESTHEDYNAMITE :
My point was one cannot have the same named promo even though at first it appeared confirmed online. If you notice the people w/ 12/20 free line promo said theirs appear "Line on Us 3 $40" (basically like how mine showed back in Sept). The point is if the promo name (or SOC) is the same, it will not stick unless Tmobile makes exception for this 12/20 somehow. The system has never allowed same name or SOC promo to stick is my point despite how many times the reps kept adding it back.

So what I'm wondering is how do we know for sure 12/20 is not some sort of continuation for 12/20 free line? I'll be happy to take another free line but I have Line on Us 3 from 11/25 and waiting for solid confirmation that 12/20 is not a "continuation" of 11/25 (same SOC code). So far no one can provide solid evidence, so I'm just going w/ my own very recent experience. I'll just wait 24-48h and hope someone can confirm their "combined Line on Us 3" stick or changes to Line on Us 4 or something....

Ur the only data point here and on Reddit that's saying it didn't stick. I've now seen line 5+ data points that are saying it's combined to get 40 off or 60 off "line on us 3". Multiple tmob reps are saying this stacks from Nov free line.

I just looked at mypromochoice, and mine still lists:

"Status: Pending - Issue on or before 14 weeks from date received/activated"

I got the deal on November 27, and submitted Dec 7 (after I received the pixel 4a 5g)

How would T-mobile know we got the Costco BYOD $200? I thought the Costco promo is a rebate with Costco so how would T-mobile find out.
Where do u think this money come from ? If T-Mobile is not paying this commission , u think whoever is administering the Costco gc is going to issue it ? T-Mobile better had this check in place as i am guessing prior Boyd payoutn on free lines are killing T-Mobile.

Or it is just a scare tactic so people will not try to submit for the $200 rebate.
