Added a line at Costco yesterday with a device I already owned. Was not intending to submit the $100 BYOD rebate as I did not want to jeopardize the status of the free line. I got a text message later in the day "Congrats! You will receive your promotional service discount from T-Mobile as long as your maintain eligibility."

Next day (today) I got another text thanking me for adding a line.

When I check my current plan, I can see that my bill has increased by $16 per month?

Does getting the line added at Costco and not submitting for the BYOD rebate invalidate me?

Will need to try and hash this out with Customer Care I suppose.

Yeah man it was a pain in the ass to converse with these people. If hiu do teu make sure they dont cheat uou kn hour charges
That's why I'm considering not even try to get this current free line because I already have 2020 2020 Line on Us 3 and 2020 3rd Line On Us 3 So they might screw up these Two lines if I get this current free line promotion.

Quick question: I added a free line 3 days ago, is it too late to get another promo combined with adding new line or it should be done same time.

Same here, I have also have:
$20 2020 Line on Us 3 (Additional Lines)
$20 2020 3rd Line On Us 3 (Additional Lines)

Which is really good and I never thought I would get them to stack. They also close this so it no longer stack for new customers. I didn't even know about these free line promotions when I created the account in November.

But I do eventually want another line. maybe wait for a 2021 free line or get this one. Not sure yet.

I added the line via my account, no human interaction, seems like it worked this time (not to jinx), last time added via chat and had a chore. Looks like it's safer to eat $10 and save a hassle by adding line via account.

My SOC is FRLTULF2. When I go in the link in the post, I see "Add a new line" on the top and when I proceed, it says $10 due today and $20 due monthly.
I saw in the previous post that once the SIM is shipped, the monthly fee will show as a discount and the line will basically be free. Can someone confirm this? 3k+ replies yet I don't see any concrete answer..
The wait time on the phone is 3+ hours so I'm willing to do it online but in the right way.

a t-mobile rep just switched my account from magenta back to one. She said she was adding back the kick back and plus promo but I don't see it. how long does it take to show up on the account? it's been a bit over 3 hours.
I also had netflix standard and was paying extra but she said the plus feature makes it free now but I don't see it.
My new soc code is TM1T12. Is this an ok code?

What's the difference between the two?

My guess is that your 4th line created this week in December qualifies for both promotion:

"3rd line on us 3" and "line on us 3"

Therefore, since you qualify for both, it alternates between them. Anyways, it sounds like good news. maybe you will continue to see alternates until 12/31/2020 in which both promos will end.

"3rd line on us 3" is for new customers only. 3rd line free qualifies for all promotions. So one can get free iphones or free android phones.

"line on us 3" is the promotion in this thread. It is good for existing customers. This promotion does not qualify for any free phones.

Went to Costco today to add a free line, and was unaware of this $100 rebate they gave me, I was very surprised. Costco reps urged me to go straight home and enter it asap, so I did. Now I'm here reading the comments, that doing this might've void my free line? Or could've has a free A11? What are my options at this point?
I doubt, I stop by at Costco yesterday to get a new line added (with free SIM and free activation). Also surprised for BYOD $100 rebate. Entered it today, called Tmobile and confirmed the line is free.

Indeed, as I am still on Simple One 2GB data plan, had to ask him to add 2GB data for the new line (looks to me it had voice/text before). Anyway, adding 2GB for free as well.

Looks to me my line total still stays the same (at least now).
