Did you get any confirmation once you added the line that free line promo worked? When i tried adding on the app it says $10 for sim and $20 monthly for the line

Sorry to be curt... but have you read even one single page of comments Smilie ? Many many folks have added line and reading would help Smilie

Using Developers toolbar(same steps you use to find the SOC) --> ManageAccounts-->Lines-->AddOns, and you should see something like...0: {billingSystemId: "xxxxxxxx", name: "KickBack™", code: "xxxxxx",…}
Quote from fithos View quoted comment :
You can actually see the Kickback on your account?
I recently lost the Kickback and re added later but I can't see it anywhere on my account anymore. An agent says the new system doesn't show up on customer account anymore. Multiple different agent assure me they see it on their end.
And now you say you can actually see it on your account.
LOL, T-Mobile customer service.

Quote from OompaLumpa View quoted comment :
I'm not entirely sure how the coding works but I believe these are not generic like kickback for instance. I think the last letter is what your designated group discount refers to since they have a variety of plans, so just give them the code with whatever your last letter is, all of mine are the same last letter. This may explain why some received drop out texts? with tmo Confused
I called them up today and they said the code is not there for them to add so I need to wait for the billing cycle end ~~

Please read the wiki about plan switch and moving over add-ons. We didn't ask them to add the ONE Plus add-on (which is a paid one) but the ONE Plus promotion add-on which is slightly different but free.

Quote from sussig View quoted comment :
I lost friend and family promo after I changed my plan. I told rep if I can't get that promo back then I would settle for hook up. He got his super to add it and I was thrilled. I never thought about asking for hookup until someone mentioned they had luck with oversea rep
Thanks for the feedback. Another unique situation with a real problem they had to fix and make good. It's more difficult if there is nothing to complain and just want to have a hookup code without even having one. I will probably wait when they are available again or in case I get a real problem in the future.
But good for you! Smilie

Thanks. I've been checking with that tool for a while now. So far neither Kickback or my 4th Free Line Shows up. I added the line since it first became available.

After discussing with rep on app messaging she said my account which is MAGENTA2 with 2020 Line on Us 3 is not eligible. Anyone else have an issue?

Exception: From December 20 - 31, 2020, customers could only participate in one of the following overlapping free line offers to receive 1 free line during the overlap period:
Get a free voice line with qualifying plan "2020 Line On Us 4"
Magenta "2020 3rd Line On Us 3"
3rd Voice Line Free Essentials "2020 Essentials Line on Us 4"
Customers will be systematically enrolled into the correct free line offer.

Just bought the Pixel 4a 5G with added new line. It said $25 monthly fee when I added the line and no new line is showing up yet. Is that normal?

How old is your account. "Magenta 2020 3rd Line On Us 3" refer to the promotion when you join tmobile with magenta plan and have 3rd line free. I'm not sure when that promotion started but if you got a LOU3 from last month. You should be able to get this LOU4. Do it yourself from the website and pay $10 for the sim. No need a rep when you have less than 8 lines
