If you remove any paid lines within the first year, the free line loses the promo and becomes paid.

TMO doesn't want people doing what you're wanting to do.

To accomplish it, you would need to:

1. Add free line.
2. Wait a year + one day.
3. Port out paid line to another carrier.
4. Keep paid line active on another carrier for 90 days (to preserve number).
5. Port old number back in on free line.

This whole process has taken you 1.25 years.
My port-in was initiated during T439 promo period and completed today outside of the promo period. Without the port in (with only the added line and traded-in) I was on a bad promo. Once the port-in completed today, the system auto updated to T439 promo in my account --> promotions. Therefore, I don't think it was a requirement the port-ins must be completed by 3/24 EOB, just as long as they are initiated.
YES, you can use this sim in your iPad. I pay for 2 lines and have 3 free lines on promotion (5 lines total)
I have 2 of my free lines in a iPad and a Samsung S4 tablet, with UNLIMITED data.
You have to call them and tell them you want to use the line (promo line) in a tablet but don't want to lose the promotion and you don't want to open a new line for this.
What they did for me, was block the phone service on the line and kept the messaging and data. That way I am able to use it in my tablet.
Every summer my daughter comes and visit from Germany. I take one of the sim card out of my tablet and put it in her phone..
I call T-Mobile and have them unblock the phone service. That way, my daughter has a phone while she is here in country.
When she leaves I call them back and get it blocked again. I have been doing this for close to 5 years. So I know for a fact it works.
Tomorrow I will be calling to try and get another free line.. (Fingers Crossed)
Hope this helps

Switched to new Magenta plan from Essential, $120 all included, 2 Paid Lines and 5 FREE LINES. 👍🏻 Essential Line on Us didn't fall off in a couple days since I switched to Magenta and added a new Free Line so I guess it will be sticked to my account.

Magenta® $120.00/mo
Applied discounts and promotions:
$10 AutoPay Discount
$20 2020 Essentials Line on Us
$25 AutoPay Discount (Additional Lines)
$20 2020 Line On Us 4 (Additional Lines)
$20 2020 Line on Us 3 (Additional Lines)
$20 2020 Line On Us (Additional Lines)
$20 2021 Line on Us 6 (Additional Lines)
Are those all new lines or existing ones and they gave you the discount?

Those who wants iPhone 12 that will save them over $800, why not spend $25 to get a new number from MVNO that is not associated with tmobile and port the number for the offer? Am I missing something here?

ETA, saying this coz no ebay options available, seems like.

Number barn- how risky is it to port from there to get the iPhone SE promo?

(Perfect time for wife's bday and higher storage! Lol)

Also rep on fb chat stated no google fi port but didn't mention GV even when I asked. Already have number barn and ready to port if someone can confirm.

I started with Essential plan with 2 Paid Lines, plus 1 Free Essential Line on Us, and kept adding more Free Lines through out last year. I reached maximum 6 Lines. Then, I upgraded to new Magenta plan, and added this Free Line. Now I have 7 Lines total.

Clearly I'm an idiot here.
I have a qualifying SOC.
No matter what I try, anything that adds a line, is 20$
I chatted, called, used the web page, the sim will be free, but then 20 a month.
What am I missing here?

Any luck finding answers or changing TM One max 8 to 9-12 plan? I am in same boat with same all promos.
Nothing yet - taking my time here to gather as much info as possible.

Still debating if i should grab a free phone or a cheap one just to take advantage of the free line phone promos.

Just do it like you normally add a line online. The system will adjust your $20 to $0 with credit.

They allowed you to keep the free lines with no additional costs? I'm on simple choice and every time I ask they said I would lose the free status. Currently on 5 free lines and 4 paid

I am thinking about adding a line and getting an iPhone 12 with the $830 credit offer on the website. I wonder if this will still trigger the free line promo
