Added line and ordered new sim with online chat. Did it in 2 minutes. He said free line credit will be applied once sim activated.
Thanks, what do you say? Do you mention you heard about a free Line deal and think you qualify? My SOC was on the qualified list. It looked like in store there are free phones when you add a line, did you ask about a free phone?

No need for snark. Hit him up on Discord yourself and ask.
Wait you mean Reddit? I just tried on Discord and there's none by that name.

i am confused, did you mean one plus 8T phone promo Or some other one plus promo? sorry, had to ask Smilie
It's not the 8T phone promo. this is an add on for tmobile one plans that gives HD video, 10 gb Hotspot and faster data speeds abroad. it now costs $15 per line but at one point they were letting you add to your lines for free so I was able to get the free version added to my lines.

He is on the unofficial tmobile discord channel at

https://discord.gg/rnbYeWm

That channel is helpful with free line deal discussions.

Do this "change plan" trick mentioned at

https://www.reddit.com/r/tmobile/...n_ios_app/

You will then see the real promotion you got is "Line on us 4".
Tried that trick but shows both of mine as LOU3 still.

I did the free line late Nov at Costco/Wireless Advocates. Did it again today 12/31/2020 at Costco/Wireless Advocates with no issues.

Interesting part was that the guy told me that the Costco $100 BYOD offer is also valid with the free line, and gave me the rebate instructions.

Any risk in trying to submit this rebate? This submission is to mypromochoice dot com

Guys I would like to ask if it is possible to ask to add kickback to new lines? as we know kickback is for lines actived before April 2018.
I want to say we know we can ask to have one plus promo added for me lines, that I have done successfully. So I want to know your experience, can you ask and have kickback add it to new lines? Or that is impossible?

Anyone know if the free line promo is stackable with the Costco BOGO Samsung Note 20 ultra offer? In store offer says BOGO Note 20 ultra when a new line is added.
yes it is stackable

Actually aside from the details of the post, where does it officially from T-Mobile say Costco BYOD is not stackable? Seems like a few other people have also received a $100 Costco cash card.

I care more for the free line than the $100 cash card, so just wanted to double check

I'm sorry what is doable? And you are %100 positive free lines won't get KB? So new paid lines could?

All my lines have Kickback including the November and December free lines. It does nothing on a free line since there is no charge to discount from. Already verified through my bill that generated the other day, no additional money off because well you can't take money off something that already doesn't have a charge.

One of my free lines I have as a second Sim in my phone to use for the data then so I ensure never to go over the 2GB and always be able to claim Kickback. Hopefully with a future free line promotion I can do the same with my wife's phone as she can have a second Sim as well. One drawback is that I lose 5G on my Pixel using a second Sim but I believe Google is working on activating that in a future update.
