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)

I have 4 lines on my plan that I pay for. I have added 3 free lines from their offers in the last 9 months. This is insane. And awesome. I hope I'm eligible to add one tomorrow.
