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.
Thank you. I contacted them with iMessage but was a no-go. When I asked to be escalated to the supervisor it mysteriously got approved. Anyways I am going to receive a virtual card in 2 weeks

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.
A lot of people that had this problem find out that the Costco raps use a different number on the account instead of the one that was ported in. Most found out by calling t-mobile rebate number.

For the Costco A11 free offer. Does anyone know when the offer will end. The earliest I'll be able to get to a costco will be 12/31. Can I add my free line first than get the A11, or do I need to do both at Costco to qualify.

Thanks
You must add a line at Costco. The offer is good till 12/31.

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 wonder if T-Mobile will let us cancel this new line we just added and then we can go to Costco to get this promo. Anyone knows if that's a possibility?

Does the sim ship preactivated and if not how much time do we have to activate it to keep the free line? I think someone said they lost theirs because they waited too long?

Depends on your plan. I have "ONE Plus Promo" on the line (as on my other lines).

"Now, activate HD video streaming and 10GB of high-speed Mobile Hotspot data for no extra charge. You will also get unlimited data in 140+ global destinations at twice the speed (up to 256kbps), included free. T-Mobile ONE includes unlimited talk, unlimited text & unlimited data.
Changes made in the middle of a billing cycle will result in full monthly charges of the new feature.
On all T-Mobile plans, during congestion, the small fraction of customers using >50GB/mo. may notice reduced speeds until next bill cycle due to data prioritization."
How does the "One Plus Promo" show up on your bill as ? I had this at some point in the past, got removed somehow and when I called customer care, they say they don't see it ever on any of my bills. In fact they say there is no such thing wherein only certain features of the One Plus Add-On were available for free. I am on the T-Mobile One Plan TIULFM9

Will try to find it. However, I doubt that will help with customer care as they are saying they dont see this feature on any of my past bills. So the question - how does this One Plus promo/ feature show up on the bill ?

I'm on the 55+ One plan for $60 / 2 lines. Went to Costco tonight and Wireless kiosk said they could not add a line to my plan. Said 55+ plans have a limit of two lines. Showed me some flyer showing plans and how many lines they can get.

Some have commented on here that they were able to get the free line on the 55+ plan. How?

ARGH! I thought I saw something that offer ended on the 24th, so I went ahead and had Tforce added the free line fearing the offer will end before 31st when I'll be near a costco.

Suck for me.

you are on the t-mobile One unlimited 55+ correct? Also have you spoken to any reps about the free line?
Quote from Thro :
I added a free line on 12/23. (2 paid, 1 free). My bill went up $20, but tmobile said when I get my sim card activated it will show discount. I'll see what happens when I get my sim card.


Wondering the same thing? Costco said no to me tonight.

Sorry just catching up here....
I'm seeing folks saying that the Costco BYOD $100 GC is not stackable with that free line, is that really the case?
Also, I've signed up for a free line at Costco last week not knowing about the free A11 deal, can I go back to a Costco and get the free A11 now? And is this A11 deal one of those monthly credit deal? TIA!

Read the wiki re Costco A11 + $100 deal. Costco phone rebates are via gc not eip.
