Still going on. No end date yet.
Thanks! Would you recommend adding the line by calling or using chat, or just add the line online and hope the promo shows up?

I would add online myself at t-mobile.com
It is up to you. chat, calling, online are all the same. There is no special promo code to add.
The promo gets automatically added to your line if you qualify.

Need to use a sim card I already have with me. Can't seem to do it online and phone rep claims it cannot be used. I'd rather reuse it over paying $10 for another sim

I'm pretty sure I qualify. I opened my account a few months ago. I got 2 paid lines and one free when I switched to T-mobile. I also have the 20% insider's discount. I tried the chrome extension to get my soc code and it was MGPLSFM but I can't get any of the code lists to load to verify I qualify.

MGPLSFM qualifies and you have 2 paid lines. So you are good to go.

Try doing it with T-Force messenger or app chat. Tell them you have your own sim, and tried to do it online to avoid the $20 assistance fee, but it's not possible. . .and hoping given such they could waive the $20 fee. . .

Did this for the LOU4 on Christmas day. They tried to upsell me to their new 5g capable sim but I declined. He has already started he would waive the fee before I asked to waive it so it was moot at that point.

I've been following the thread for many pages and assumed "A11" as Apple Iphone 11. I was totally oblivious to the actual substance. It's true that these acronyms nowadays are mostly communicatively embeded. LMAOHa ha

Can you use an old sim instead of them sending a new one? When I switched to T-mobile a few months ago they gave us sim cards to put in our old phones to use while we waited for our new phones to show up.

Usually you cannot reuse an activated SIM - but easy solution: Almost all TMobile stores will exchange it for a new one free.
