Quote from Thro :
I added a 3rd line on T-Mobile ONE Unlimited 55+ ($70/2 lines) calling t -mobile. (see my other post). https://slickdeals.net/forums/showpost.php?p=144227348&postcount=3593
Maybe it does not work on the Magenta 55+ or ($60/2 lines) plan.

I don't have the Magenta plan. I have the One Unlimited 55+ plan for $60 (got in March 2018 right before they raised it to $70).

I believe my SOC code is ONE60TIFM which I don't see on the sheet. Thro - what is your SOC code?
My SOC code: ONE55TIB

If one is maxed at 12 lines combination of mostly paid and a few free lines and new promo comes about to add a free line.

Is it possible to convert one of the paid lines to free during the promotional timeframe?

This is my case - with the addition of this free line, i am now maxed at 12 and I have read where you will need to wait 1 year to cancel/port out a paid line then wait another 3 months to port it back into the free line.

Unclear - If I add the line, how long do I have to add a device? Specifically, the 50% off Pixel - Still figuring out if I really want the phone, but don't want to lose out on the line.

If it's any consolation to you, I still havent seen LOU 4 yet on my account as of now. However, on the bill which generated two days ago, the amount is correct. They did some real funky math. On my previous free lines, they just gave me a credit to offset the cost of the line on the line. This time, the account cost went up by $20 and then they credit that back on the line. They somehow used the LOU3 code twice for two different amounts on two different lines.

Conventional wisdom says 30 days if I recall correctly, and I think I did this before 1-2 weeks later attaching a phone order to a fresh line. However, one chat rep yesterday said phone had to be added the same day as new line and iPhone SE wasn't eligible. I said OK and will try another rep tonight as I believe that is wrong.

Edit: Actually, I recall TMO pulled a number on this with a prior phone promo that they stopped after the free line promo ended (I think line 2 or 3 this year) and restarted it the day later. But now they created two promo periods and denied all add-on phones as the promos were not running at the same time. Thus, definitely do it while the free line promo is going and don't wait until after. But within it should work.
