Yes, I was able to get the rep to waive the SIM and support charges. When asked, the rep was nice enough to add the one plus promo on the the new line and included 2 day shipping on the SIM.
You'll lose the free line as the One Plus free phone promo IS NOT ELIGIBLE....

I called and they let me add a free line to my old unlimited family plan that has 14GB hotspot included. Any suggestions for a cheap phone to use as a hotspot?
What is you plan/SOC? Smilie

My plan is FRLTULFM9 - which is missing on the SOC list - just talked to T-Mobile rep on chat and confirmed my plan is eligible.

Free line added and waiting for SIM card now.

By the way, T-Mobile rep confirmed that No promotions could be combined with this "free line promotion" together.

That's the ineligible plan I have as well. Did you lose any of your kickback or data when you switched? I am contemplating it to get the free line for my kiddo.
Read my post "Still on TMO ONE All In Promo plan (FRLTUL2LP) which is never eligible for free lines?" in the wiki here:

So the free line isn't compatible with the PROMOs but is that only if the PROMO is on that line or on any line?

FRLTULFM9 is on the eligible SOC list.

I have 11 lines, 5 paid and 6 free with one Proxy Digits Line. Since one is not getting kickback and after all other discounts, my monthly is $102.00, excluding EIPs. So, I have one more slot left for the next free line promotion. Since switching from the 8 line to 9 line, my bill actually went down a few dollars.
How did you get kickbacks on the free lines?

Had started with T-mobile in Nov 2020 for 2020 Line On us 3 (using Costco 200 rebate)
Resubmitted for $100 promotion for port-in.
12/22 - added a new line for free (except SIM cost) for 2020 Line On Us 4 but no phone.

If anyone got a free phone, pl let me know.
Costco's running free A11 via virtual prepaid card plus $100 Shop Card when you activate a line there.
Promo code: 2020COSTCOSAMSUNG7

I really wish it was like this where free line can't be stack with any promotions at all. This will cut out all the confusion of people trying to stack this and that.

But T-mobile is a big YMMV company and you have people coming in every other hour saying they got this phone free, that phone free with the free line.

No kickbacks on the new free lines. Two of my old free lines have them, but never received kickbacks because the lines are free. So, I never bothered asking the reps to add the kickbacks on the new free lines. Only asked them to add the one plus promo on the new free lines.

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.
This year there have been 4 lines on us. June, September, November, and December.

I don't know why it is ymmv. System either accepts it or rejects it but as terms say it may take a month or two to find out if system accepts it. I discovered one clue is terms and conditions of promos. They are phrased a bit differently. I haven't seen the TC for this promo though.

By the way, most TMobile reps don't have a clue. So they didn't 'confirm' anything.

Via leaks from reliable insiders/employees. These threads tend to compliment the reddit threads of the same topic.

I really want to get in on one of the hookup deals... But I'm aware that may require a new account. Hard to get off of the family plan I'm on now and suddenly have to pay $80 for two lines and wait for the free lines to come... And in 2019, there were none!!
