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:

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)

Most of the time, Senior plan, First Response and Military Plan always excluded.

Just worked for me on my military plan.

My agent told me my military plan is not qualified.
12-20-2020 at 06:26 PM
T-Mobile ONE Military plan here, not eligible for this promotion according to the dude on the 611 line
12-21-2020 at 09:37 AM
Military plans all have different SOCs. Please refer to the instructions above to determine that.

There's no catch, once they have you signed up with a bunch of free numbers though it'll make it very hard to leave them.
12-19-2020 at 08:19 PM
The only catch is if you don't have a Taxes Included plan. You would then pay taxes on the new line.
12-20-2020 at 11:52 AM
This will also be a win for T-Mobile because from a marketing and advertising standpoint they can say that they’ve added “x” number of lines for the past quarter/year.
Joelioli asked this question on 12-19-2020 at 08:48 PM
12-19-2020 at 09:19 PM
Generally after 1 year you can. You would still have to likely maintain 2 lines to keep the free line.
12-21-2020 at 10:49 AM
How to know which line is a free line?
12-23-2020 at 05:23 AM
I removed a paid line in May. Added a free line in June or so. Also removed a paid line 2 days ago and added a free line several hours later the same day. I’m still waiting to see if this particular promo will show up on my account.

Most likely not since it wasn't last time. I had to switch to MAGENTA2 to get it.
12-21-2020 at 10:23 AM
I was told by the chat rep that Magenta Amplified plan customers are eligible for this promo as well. Try again and post your finding.
12-22-2020 at 12:34 PM
I'm on MGAMP2 and was told by chat rep that it's not eligible.

I just did an on-line chat with T-Mobile and was told that the Magenta 55+ plans are limited to 2 lines and therefore are not included in the free line promotion. If anyone gets a different answer, please post!
12-20-2020 at 11:14 AM
Agent said regular magenta and magenta plus are qualified.

I have the TMobile One all on us plan paying $80 for 3 lines with discounts. FRLTUL2LP
The rep tried to move me to Magenta saying for 90 a month i can have 4 lines and the plan is almost identical.
Is that true? Thanks so much to anyone who can help!
Ask them what SOC (https://docs.google.com/spreadshe...340439917) that would be and then check and confirm yourself before making a mistake.

I was on the same plan (FRLTUL2LP) until yesterday and then had luck with a T-Force rep on Twitter who allowed me to change to the T-Mobile One plan 2 for $120 (FRLTULF2) and moving kickbacks and All In One promo over to the new plan. This plan is still a bit more expensive ($100 for 2 lines after kickbacks) but
- it finally allows to add free lines (and I hope there will be more of those in 2021)
- it has Netflix Standard HD included or with a $3 supplemental fee which my wife wanted to have anyway
- I still have a separate $15 T-Mobile Connect line which I can then stop paying in favor of the free line

So for me it worked out. The 611 overseas rep was then even able to add the One Plus Promo add-on also to the new free line.

FWIW I was strongly considering adding the free line and using it on my physical SIM card on my dual sim iPhone 12 and then switching my existing line to the eSIM so that I can use all the data I want and still receive Kickback on my line, but realized the when you activate dual SIM you lose 5G service. Bummer.

Ah ok. As the All In One Promo wouldn't work/be available on a Magenta plan, of course. If you don't have the promo on any of the existing lines it might be more of a hassle to fight it back.

Mine got removed at the same time when I opted into the free Netflix. It was technically a new plan. Didn't notice until wayyy later that it my one plus promo got removed. Haven't been able to convince a rep to add it back. That 10gb of 4g hotspot was where the value was, 3g hotspot is literally unusable.
That make sense. Maybe in a year or two they'll upgrade everyone to 4G bc 5G is the norm.

Added new line myself online Sunday night, just got the text confirmation of the promo and the SIM shipping email this morning. Can also now see the new line on the account with the doubled 2020 line on us 3 credit amount (also got the free line in November).
Same except I add new line yesterday. 2 paid lines plus 4 free lines for $96/month.

Thanks Jman100! I tried to rep but SD won't allow.

I was considering the exact same thing but then stumbled upon the same limitation.
Quote :
While using two lines in Dual SIM mode, 5G data isn't supported on either line and will fall back to 4G LTE. In China mainland, 5G data is supported while using two active lines in Dual SIM mode on the line that's using cellular data. In China mainland, while using Dual SIM with 5G, 5G Standalone isn't available.

I need to find out if I can switch numbers and lines within the account so that I can move a heavy data number to the free line to continue to receive kickbacks on the existing line. If that makes sense. Wink

Looks like my code is eligible, but a tmobile rep in a sales office near me (wait times too long on tmobile.com) told me that it would be $30 to get tmobile sim, to port over that additional line. is that true?

It's $10 for the SIM card and $20 for activation. Sometimes you can get them to waive or credit those fees.

Free at Costco or I saw adding an line online waives the $20. If you call maybe you can say you would have done it online but you wanted to get the promo so they should waive the fee because you had to call.

if you are not in hurry, you can do it online yourself and save $20 or talk to a rep and ask him it waive the fees.

I see this -
$20 2020 Line on Us 3 (Additional Lines)
I now have a total of 8 lines on MAGENTA2. I was expecting the

$20 2020 Line on Us 4 (Additional Lines) since I didn't take the free line offered a month ago.
I'm starting to think there will be a lot of hassle to get this corrected (as always when adding something to the account). In the past when the promo is applied correctly it usually appears instantly on my account.

Someone has mentioned before that LOU4 kicks off LOU3. I'm starting to wonder if the Nov line is no longer free and that's why the reps keeps telling me the credit is applied to the new line, but my total went up by $30.
