I agree, however. One plus 8 phone are not stackable per Op. You will get the One plus 8 for free. You will have to pay for the new paid line 🤨
In your case , One plus is free if you trade in , not because you added a line .. just do the math in getting a phone for trade in vs paying 50% for iPhone se or pixel..Tforce confirmed me ..

Yep, if plan is eligible
Is it possible to:
1)convert a existing paid voice to mi to make room for a free line, especially since there is a $5 mi available on TMo1 even if the last voice line added was <1yr still
2) swap the numbers thereafter from New voice to converted mi

Ive called like 6 times today, every rep tells me that plan is no longer offered. My only options are essentials and magenta/+.

Essentials would keep the cost the same as I had but lose some features and add tax.

Magenta is about $30 more a month but would gain netflix.

Not sure what to do here.
I've read some people were able to find a sympathetic rep to add the 20% off code onto an account. I believe it was a Magenta plan. That's worth a shot in my opinion. The nice thing about Magenta is free lines really are free since the price is after tax and fees.

I think that was a 20% off Insider Code, but I can't remember if that's the exact name.

Thank you, we settled for the Pixel 4a 5G 50% off without trade in and zero down. The lady initially said free line is eligible for buy one get one iPhone up to a value of $750. I didn't buy it, supervisor jumped in and straightened it out. Supervisor said cannot be stacked at first but then corrected his mistake.

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!

AFAIK, the BYOD $100 Costco card deal cannot be combined with the free line promo. I already had read that in the sticky, however like you, I figured it won't hurt to ask. The rep said it couldn't be done. When I asked if I can combine the free line promo with the free A11 + $100 Costco card or 50% SE + $100 Costco card I was told yes definitely.

I chose to go with the SE since the reviews for the A11 were pretty terrible. This is for a spare/consulting work line, but I didn't want to deal with a slow budget phone. For people who want a free line and $100 Costco card and don't care about the phone received, the A11 is probably better.

The $100 cash card is not from BYOD. It's from purchasing a phone from Costco.

Yes, I did this about 2 hours ago. Supposedly the SE deal is extended until 12/31, but don't hold me to that haha. That's what the rep told me, however I didn't take the time to double check on their promotion sheet.

I'll prolly just give them a call early in the morning to verify it and go. Thanks for confirming though.
