I see someone asked if you can add a free line and cancel a prepaid line later and got a positive answer. My questions is what's tactical way to do this and still keep the number.

for example, I have 4 paid line right now. let's say 1111,2222,3333,4444 which all my friends knows. If I add a free line ,I will get 1234. My question is if there is anyway for me to cancel one of my paid line down the line but still keep 1111,2222,3333,4444?

You need to wait 1 year after adding the free line and don't add any other lines. Port the number you want to keep out to a different service for 90 days then port the number back into the free line.

Yes. After a year port one of the four 1111,2222,3333,4444 to GV ( paid $20). Let it stay there for 90 days, then port back in to replace 1234 ( free line ).

The lines you have the free mini on should all be 2020 Apple Trade P29. I ordered 5 of the mini's and the system put them As the 2020 Apple Buy 2 P11 so it was making me do the buy one get one. They fixed all the lines to show 2020 Apple Trade P29.
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.

You will get a virtual prepaid card after the A11 rebate is approved. The $100 Costco Shop Card is also via rebate.

My club said it was Costco policy that all phones are tested, boxes opened after purchase. The front end person took the new phone to the wireless kiosk to complete the transaction.
Can you post the Costco rebate promo code for the A11 and the $100 shop card? I added a line at Costco and was given a $100 rebate form BYOD promo T01568, not stackable with the free line?

The A11 promo code is 2020COSTCOSAMSUNG7.

My $100 Costco Shop Card was not the BYOD offer. The promo code is T01501 for a device purchase.

You're welcome.

The promo date for the $100 cash card is 12/1-12/31/20 so it shouldn't be a problem.

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.

Thanks, took only a few mins to get the free line added to my account. The rep mentioned this offered is not stackable with any other offer or free phone. I even had them escalate to the manager and he said the same. I am on Magenta Amplified plan with 4 lines for $160. Now I have this free 5th line with same plan.
Did you actually get free line on amplified plan? Have the discount shown in your account yet?

Just as a data point:

I ported 4 lines over from Verizon during September 2020 when T-Mobile had the BYOD $250 promotion. I was lucky to get 2 free lines then along with the 20% insider promo. Was able to get waiver for sim and activation cost.
My account showed:

$20 2020 Line On Us 2 (Additional Lines)
$20 2020 3rd Line On Us 3 (Additional Lines)

I am on Magenta plan. My bill was $96 per month.

Following JMan post, added another line during thanksgiving via T-Mobile chat on app and lucky to get the sim and activation waived. Also received the $100 card from T-Mobile for porting a ebay Verizon number over.

That line showed up as:

$20 2020 Line on Us 3 (Additional Lines)

Added another free line via T-Mobile chat on December 24 (got sim and activation waived again)
As with most other users here, it doubled the discount as below:

$40 2020 Line on Us 3 (Additional Lines)

My bill got generated this morning and all has stayed the same

Looks like this now on bill:

Account Magenta®
Includes $10.00 AutoPay Discount and $24.00 New TMO Insider Voice 20% $96.00

(xxx) xxx-xxxx Magenta® Included
(xxx) xxx-xxxx Magenta® Included
(xxx) xxx-xxxx Magenta® Includes $5.00 AutoPay Discount and $20.00 2020 Line On Us 2 $0.00
(xxx) xxx-xxxx Magenta® Includes $5.00 AutoPay Discount and $20.00 2020 3rd Line On Us 3 $0.00
(xxx) xxx-xxxx Magenta® Includes $5.00 AutoPay Discount and $20.00 2020 Line on Us 3 $0.00
(xxx) xxx-xxxx Magenta® Includes $5.00 AutoPay Discount and $20.00 2020 Line on Us 3 $0.00

So looks like I am all set with bill staying at $96 for 6 lines (2 paid and 4 free)

Thanks JMan and everybody on this thread for the help!

I was told my One Plus Promo account wasn't eligible because I already took advantage of a previous free line. Did anyone get this to work that is in the same boat as me?
