It's free. Free is always good. And after a year. You port out a paid line. Then port it back onto the free line. I've done this 5 times. Slowly you can work up to all free lines. If I can snag this I'll have 4 paid and 6 free this time next year.
fix=Slowly you can work up to all [but 2] free lines

I currently have 5 lines on magenta max: 3 PAID and 2 FREE.
T-life chat just said I can't have 3 paid lines and 3 free lines (6 total. Is t-mobile getting smart on the ratio or am I not eliglble?

"Any account can only have two free lines when your total lines are six. With five lines, you are already receiving two free lines, so adding just one more line does not make you eligible for another free line. If your account reaches seven lines (with four paid lines), then you can have three free lines. Please let me know if you would like to add two lines to get one line free."
That's BS. I have 8 lines, 3 of which are paid. And none of the paid ones were added later.

I'm on the old Sero, AKA SWAC, which I believe is called Advantage Unlimited nowadays.
Any data points whether it's available, without risking the plan?

Also, I have another phone on the Kickstarter plan.

I really need this to get rid of my other Google Fi line and park that number. Does anyone know where I can park my number besides Google Voice?

I was told in the past that a byod line means that you will never be able to use it for any phone promo. Is that still true?

So I got the pop-up in the T-Life app. I'm too paranoid to do this deal since my coworker (he's on the same SCNA 10GB Family Match Promo plan) did it back in April and the line wasn't free, but worse, it messed up his plan, his monthly cost doubled and it took him 3 months of constantly calling to finally resolve it and get his old plan with all the perks and discounts back. May not be worth the trouble. I rather the T-Life app allows me to do the line add attached with the promo. I don't want a CSR touching my plan if he/she is not careful.

well, technically t-mobile does not need to know. if you trade the 9 and google takes it locked then it won't show up any longer on your t-mobile account, but as long as you pay your monthly bill you will still get the credits for it. You just CANNOT pay it off. Technically, there is a little risk involved but let's just say it worked fine for me and others so far. If you are already on then 10+ bill credit you could just do the swap at the google store and likely get an unlocked pixel 10 from them, right?
thanks for this! didn't even think what would happen, but it makes sense that they wouldn't know. also found a reddit post corroborating, so i think i'll give it a shot https://www.reddit.com/r/tmobile/...t/nebkcfd/

My understanding with dealing with TM promos for so long is, if you really have the segment then you can Add the line yourself, go thru Costco, instore, or any sales channel.
The system will automatically pick it up. That's why the people playing CSR roulette most likely will get burned by somebody lying to force a sale.

So if you are afraid, just Add it yourself and if not really free then ask them to remove it and credit what you paid.

I bit the bullet and went for it through T-Life chat. At least I have everything in writing in the chat and she confirmed everything, that line is in deed free (just had to pay $10 connection fee) for my account and NOTHING ELSE will change (except I have to pay $5ish taxes extra monthly). I asked her like 3 times to confirm and she assured me. She gave me the ID for the chat transcript for my OCD paranoia. I have a spare Samsung S25 that used esim to activate it immediately, took like 5 minutes and it was active. Now just waiting for the promotions in my account to really reflect the free monthly credit and hopefully my next bill is not some weird plan change. So far I still see I'm on the same plan and the new line listed. Hopefully it's all fine; I have gone through hell before so I don't want to go through it again 😬

UPDATE : An hour after I added the line, I can now see this in my Promotions section in my account, so that's a relief. Ok hopefully there's no other change. If you have a spare esim (even on an existing phone) add the line via that method and the account should show the update right away. If you order the physical sim card, you may have to wait until you activate it after receiving it in the mail to set the promo live in your account.
