If this line processed as 2020 Line on us 3, does that mean I can add another line and it will be processed as 2020 Line on us 4? Thank you in advance.
No, you can only do this deal once this week.

It may show as "3" on your screen, but in the backend, tmobile knows it is "4".

Just be careful if you truly have USCFM4 as your current plan. many people in the past have been told by reps that this plan was eligible only to be burned months later when they find out they are still getting charged for the new line. YMMV on refunds
I have same plan and wonder what the difference is? I have Line on US #2 and #3. #1 was different story. Still have to call about being reimbursed a month. The discount did not stick. #4 I was told the plan did not qualify.

I received a free line back in 2017 that did not stick, but they eventually fixed. So I was a bit ticked when they couldn't fix #1 this time. When ordering online, it will tell you after the order whether you qualify or not.

The TMobile rep I'm chatting with swears that I can stack the free Oneplus 8T 5G with the free line, but it'll probably be a big pain to make the line free, right?

I have not done this myself, but this is from reading all of the pages since Sunday.

You have to get a very patient rep, preferably via a recorded medium (twitter, FB), and ask them to make it possible to add more lines. I am not sure about simple choice, but with TMO One, you can usually find someone after-hours who can change your SOC to a TIXXXX9 or FRXXXX9 (the last number indicates the minimum amount of lines the plan came with upon inception. They may have to manually move over every single add-on, such as kickback, One Plus, insider, etc. Possible, but not the easiest thing.

I am maxed out at 8 lines now...when the next free line comes (rumor has it to be in January), I will have to do this.
Well hopefully you are successful. Which SC plan are you on that only has max of 8 line's? Thanks and have a great day!

I'm not sure which # aligns with which line on us that you are referring to. There were some line on us promos before this year that were eligible with this plan, but from what I have seen, none of the line on us offers this year have been eligible for the USCFM4 soc. I think some people may have gotten lucky and been given a free line this year, but seems very YMMV.

Answering my own questions here as I'm finally able to call in and talk to a T-Mo Rep. So, these free lines are meant to be used as voice communication and with that, can't be converted to other types such as for SyncUp Drive because they have special SOC.
buy a cheap unlock phone. put the free line sim in and turn on hotspot. Then you have wifi in your car.

The next free line deal could be 2 months away in February-March 2021 based on past deals. Keep an eye out on slickdeals for the next free line deal.

I was able to answer my own question after some back and forth with T-Force on Twitter and it seems to be possible.

ME:
I am very sorry, it still doesn't make sense to me. Smilie You said: "No matter the number, the line created on 12/21/2020 is not eligible for Kickback, while the line created on 11/29/2016 is." So if [my wife's number] 6747 is moved to the [new free] line created on 12/21/2020 that line would not receive a kickback which is fine. But [the new free line number] 7957 would then be on the line created on 11/29/2016 which supports kickback if used less than 2GB. This is how I understood it would work. Or do I still mess things up?

T-FORCE:
Thanks for allowing me to do a little more research. So what we can do is a number swap, to switch the line associations. This will allow your wife to use the free line created on today [as it is free she can use as much data as she wants] and then the number created today would be swapped to the line created in 2016 [which supports kickback and would trigger the $10 discount when data used less than 2GB]. We do suggest that you wait at least 2 bill cycles to do this, just to assure the promotion for your free line is in place and no concerns are caused. You can just reach out to us here after the timeframe and request a number swap between 6747 and 7957. All of the notes I have posted will be here as well as our full conversation.
I tried to make the number swap happen for almost 2 years and failed. I could not find any rep who is willing or have the know how to do this. I will be very keen to know how this pans out for you. Thank you for keeping us posted
