Background:
I have a Magenta Plus Biz plan with 2 paid lines and a free line when I signed up for service over a year ago.
The Costco Experience:
The Costco guy tried to add a new line for me via the computer system and it didn't work, so he had to call in and get them to add it. It was added. Costco gave me a sim card and a new phone number for that sim. Took a while since T-mobile phone support seemed swamped.
The one mistake I made was that I forgot to bring in a spare phone (BYOD) that had never been on the T-mobile network before. But I had my old t-mobile phone which is now on Visible service (I put the sim from the Visible iPhone 12 Pro Max deal into my old t-mobile phone). T-mobile seemed to be ok with the IMEI when the Costco guy read it to them, so maybe it doesn't matter if the device *USED* to be on t-mobile now, as long as it's not a current t-mobile device? (Maybe someone can clarify this)
Costco guy filled out the $200 rebate paperwork for me and now I can enter it into the rebate website for my GC. He mentioned that when I enter the info into the rebate website, to use the IMEI that was written down, but that I can actually put the sim card into any other phone and still be eligible for the GC. I think I'll swap my visible sim to another phone and put the t-mobile sim into the phone with the IMEI that I gave (just in case they do some sort of checking).
Line on Us Promo:
I haven't logged into my t-mobile account to see if the Line On Us promo shows up yet - does anyone know how long it takes for that promo to show up?
Anyone else have any experience like this?

Give it a day or two for the system to update. My account showed an increase in the cost after the line was added and the 2020 promo on us did not show up. After a day, the account updated and the "extra" charge dropped and is now showing what it was prior to the added line.

When filling out the $200 Costco rebate, do you enter the "Activated Permanent Number" (temp number) or the ported number?
