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)

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

Just worked for me on my military plan.
12-20-2020 at 11:11 AM
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.

depending on which device you use, some phones (like my S10) has data saver feature which you can toggle on/of.
Also, under settings ==> mobile data usage, you can set warnings to alert you when you go over certain thresholds, you can also opt to turn off data when you reach that threshold.

In general, are these free lines eligible for promotions? I know there was a list that they weren't eligible for at the time... but could I go to Costco now and explore one of their iPhone 12 promos?

Did anyone attempt to file the Costco 100$cash card rebate form and got a response with keeping the free line?

I added a free line at Costco which successfully applied to my account (bill reflects it). The rep also gave a rebate form for BYOD promotion for Costco 100$ cash card. As the OP said they are not stackable I didn't fill the form, but just wondering if someone did that and still has the free line?

(PS: Last day to fill the form, so wanted to know I'm not giving up 100$ Smilie )

It's a risk you're taking vs keeping the free line.

I submitted mine.. I'll raise hell with Costco if my free line got canceled (the rebate form was given to ME automatically)

Sometimes you eat a little to save a lot...

I got charged 3 weeks on one of my "free lines" because when I ported a Verizon number into it, the Verizon line became the "free line" and the temp number got charged.

I hopped on T-force to complain and when she said "well let's check all the criteria and make sure you actually qualified for the free line" I said, peace out. No worries. I'd much rather eat the $22 then have someone in the Phillipines mess up my account.

IMO, same goes for the $100 rebate. I'll save over $450 a year with that "free" line... not worth the risk.

New Data Point: New bill generated, 2nd one since getting LOU4. Still have both LOU3 and LOU4. No issues there. Also, the Kickback on the free lines while technically doesn't do anything since it's a free line, changes the discount to make it a free line. In my case, December bill LOU4 was $5 AutoPay Discount, $10 Kickback Discount and $10 LOU4 to make it free. For January I made sure to go over 2GB data so Kickback isn't activated. That line now is $5 AutoPay Discount and $20 LOU4 Discount to make the line free. So same total amounts of discounts, they just adjust the line discount based on whether Kickback is meant or not.

An interesting observation, if you can see what do you see. I have both LOU3 and LOU4 on the account. Received a text that have been disenrolled from the promotion one day before the last bill was generated. When bill came it had both promos LOU3, and LOU4, and both lines were free. I still see LOU4 under Account-->Plan Details. However, T-Mobile seems to have updated website and Android App, and if you go to Bills --> My Promotions, it gives you consolidated view of all device and service promotions and LOU4 shows as past promotion with end date as a date I received the disenrollment text. Can you see what do you see?

Also, Just curious, how were you able to add Kickback to that line, did you change plan?

Both LOU3 and LOU4 are listed under My Promotions despite getting the text I was unenrolled.


When I added LOU3 and LOU4 I asked them to mirror my other lines. Took a couple times to get everything squared away for LOU3 to get everything mirrored. LOU4 was smoother.

I just randomly looked at app and saw the new layout. I am having the same issues as you. LOU4 shows under plan details but shows that it ended under promotions which was when my first bill generated I think.

First bill after LOU4 was fine so I am going to wait for second bill to generate and see what's going on. Generates soon.
