Does anyone know if you get the iPhone SE at Costco for 180, do you get the 100 for adding a new line on top?

I wish T-mobile would specifically state the terms of these promos so it is known exactly what is included and what is excluded. Even many of their own reps don't know the details of these promos, hence all of the conflicting info here. Since the merger, it seems like T-mobile has gone downhill.

For example, I just had a $100 rebate denied for adding the LOS 3 promo at Costco in November. I was told Costco was an ineligible location for activating the line during the promo. I complained, so the rep ultimately credited my account $100 as a "one-time courtesy."

I thought about doing this LOS 4 promo as well at Costco to buy the SE at 50% off. However, I don't feel like spending hours interacting with T-mobile if they screw up my account.
Mine was denied as well for the LOS 3 promo. Who did you complain to?

My SOC was on the spreadsheet, so I called last week and added a line. But my bill arrived this week showing a new monthly line charge and no promo. Called customer service again today and was told my account was not eligible for the promo, and they removed the line and reversed the charges. I don't want to try calling again and spend any more time on the phone with them so I'm giving up.

I have the TMobile One all on us plan paying $80 for 3 lines with discounts. FRLTUL2LP
The rep tried to move me to Magenta saying for 90 a month i can have 4 lines and the plan is almost identical.
Is that true? Thanks so much to anyone who can help!
Did you get any resolution on this? This is exactly my case and would love to add a 4th line and pay 90

Did you have to call/chat with T-mobile to get it fixed? I have the same problem but a previous rep told me to just wait 1-2 billing cycle.... I got 2 mini's and on 1 line it shows P11, while the other one shows NO promotion.
I got all mines fixed while chatting on Twitter. Also will long into my T-Mobile and saw them updated to the right promotions as pending on my account.

Call the number displayed on the rebate status page. asking the rep to specifically check if the line that entitle to the rebate matches whatever they see on the request. Show him/her that you line should qualified for the rebate. The rep should be able to override the denied status and approve it for you. Once it is overridden, the status will update to "Received", however you should be able to get the $100 virtual card in 2 days. That is what happened to my case, hope it helps, cheers.

I am in the same boat and have the same question if anyone knows.
So, I just chatted with T-force and they confirmed that my free line (which was added on 12/24) will be eligible for the Iphone SE 50% off promotion. I guess now the only question is if Costco will sell the phone with their current promotion eventhough I already have added the line. Any thoughts?

I didnt trust the rep as I believe the plan would be a huge downgrade even though she said it is almost exactly the same.

Ask the rep what SOC he/she would put you on and what the rebates would be to get down to $90. You can then do your own math and confirm if true.

Be aware that not all add-ons on T-Mobile ONE exist under Magenta plans. For example kickback.

I moved to another SOC but stayed on a T-Mobile ONE plan and moved ONE Plus promotion and kickbacks over to the new plan. See the wiki for more details.

Yes, in same or similar situation with an older Simple Choice plan. I did not bother trying to get the new free lines from this year (I got in of 3 of the 4 offered) to the unlimited data. But I think I prefer it this way because the free lines have 6GB of data with Data Stash.

You don't even need an actual phone they will just register a dummy phone on a sim when you pop it into any unlocked phone it will work.
Repped, Do I just add a new line on tmobile.com and then call them to register that sim onto that line?

So does this new one show up as Line on Us 4 or Line on Us 3? I added it earlier today and I see $20 credit for Line on Us 3, it used to show $10 before

There are others who were eligible with Simple Choice plans. You should search the thread.
I don't know if T-Mobile can enable additional promotions on ONE plans if you haven't had them before. I don't know if kickback exists under Simple Choice. I moved off that plan 3 or so years ago and don't remember.

I contacted T-mobile via Twitter. They are painfully slow to respond these days but at least they are cooperative, or have been to date anyway.
