I just added a free line 2 days ago on 55+ . (2 paid, 1 free). My bill went up $20, but tmobile said when I get my sim card activated it will show discount. It does not sound right, should the line be free whether I use sim card or not? I'll see what happens when I get my sim card.'
I tried adding the free line for my inlaws but was told by the rep it was not eligible. Same thing last Nov on LOU3.

Doubt it right now since there are no insiders promos running. Mine was added when there was insider promos for new customers, but the agent went ahead and applied it to mine and it took effect anyways. I'm guessing the criteria for new customer isn't a requirement in the billing system, more like a consideration for the CSR when applying to an account (obviously mine didn't care or didn't know). Funny thing was I didn't ask for the insider promo, I asked for something else, but I'm not going to turn down a permanent 15% discount.
I have the same plan that you have but I lost friends and families two lines on us. I also missed all free lines on us.

I want to get my son a Timex kids watch so I can keep in touch with him. I know I'm eligible for the free line, but wanted to know if I can use that promo for the watch instead of a new phone line. Thx

I called TMobile this morning and they said Iphone SE 50% off promotions could not stack with my simple choice plan. Anyone successfully stack this offer?

Congrats! You will receive your promotional service discount from T-Mobile as long as you maintain eligibility. I jjust got this text from T-Mobile a few minutes ago. So all you of you trolls who believed this was fake news sit down and cry, lol!!!
When did you add the line? What does it show on your account for promo?

I went back to Costco after adding the free line few days ago. I was told I am able to still get the free A11 for free within 14 day window. My question is, will this disqualify the free line I got or will it work as it does say that offer is stackable. Anyone did this?
