I'll prolly just give them a call early in the morning to verify it and go. Thanks for confirming though.
Can this be added after the fact? I already added my free line on Thursday.

I did this at the phone kiosk inside Costco (need to be a member):
1. Confirm with agent that you qualify for a free line (I used the browser extension in the thread sticky and confirmed with the SOC code list). My T-Mobile account is new so I can't add a free line in the T-Mobile app or online anyway. The agent helped me move to T-Mobile 3 weeks ago and was familiar with this deal, since I'm sure a few people have taken advantage of it so far.
2. Buy T-Mobile iPhone SE 2020 64GB at Costco 10% discount ($359.99). I paid $27.90 in sales tax. It's sales tax off the full $359.99.
3. Agent will then enroll your new free line and activate your new phone.
4. Agent will provide you with print outs to apply for the $180 T-Mobile prepaid credit card rebate (it's not $200 like buying the SE direct with T-Mobile because the Costco price is 10% lower). Agent will also provide a print out on how to apply for the $100 Costco Cash Card. Both arrive 12-14 weeks from the date of submission.

You're also able to buy the SE 128GB, 256GB variants, if available in warehouse. At my warehouse they only had 64GB in Black or White available. However AFAIK you'll only get a maximum of $180 for the prepaid credit card rebate. T-Mobile website specifies a maximum of $200 in EIP credits regardless of which SE is purchased on that deal. By doing it at Costco you don't need to deal with the 12 months EIP credits, and just receive the 50% credit all at once.

My end cost for the SE is $107.89. Plus the free line of course. I'm on Magenta2 so all taxes and fees are included, carried over from my paid lines.

Hope this helps!
Thanks for replying. The 100$ Costco cash card that you mentioned, is it for opening a new line or something else?

I believe within 14 days they might be able to do something for you. But confirm first

The $100 Costco cash card is for buying the SE outright from T-Mobile through Costco. It's one of Costco's standard deals, however usually it's $30. You will also receive this if you opt to get the free Samsung A11 Costco deal.
