They charged me $10 (sim) + $20 for the representative to put in the order. I asked if I could go online and place the order myself without paying the $20, so they said they would waive the $20 fee for me, so I only had to pay for the sim card.
Also confirmed that the $100 rebate to port over my number would work, I would just need to start that process once I get the sim card.
1) I am an existing customer with 3 lines ( Third line was a free line added last time they gave for free)
Called today and asked for upgrade options
CSR : mentioned that if I would like to add a line than I will be eligible for BOGO
I Said --- Let's cancel the third line I have and you can add a new line ( Free)
CRS.... yes that's do able
canceled the third line and added a new line ( $10 for new SIM)
Ordered 2 new phones- agreement for 30 Months bill credit
just paid taxes... $130+ Sim
Now I can sell my iPhone 11 on 3rd party site for a chunk...which mitigates my $35
Hoping I got a deal
The discount on the phone is only taken when you checkout online and add a new line during the same process. I'm not understanding how, even if stacking WERE allowed, you could successfully get the discounted phone when you're adding a line and buying a phone in two separate transactions.
Would love any info!
I chatted with the rep who said my First Responder was eligible for this, and I could stack it with the 4a 5G new line/trade promo...but I did not see an area to type in the promo code after I go through processing the Pixel 4a 5G, it says I would have to pay an extra $10/mo for the new line

I went to Costco and added a new line with port in from Verizon. All went well. But when I check my online account, I do not see "2020 Line on Us 3", but rather see "$4.00 New TMO Insider Voice 20% (Additional Lines)" added.
I contacted TForce via Twitter. Any thoughts from the community?
1) Make sure you have your BYOD phone with you as the IMEI will be needed. T&C states that you MUST use this device on new number for 3 billing cycles.
2) Visit Costco and locate membership wireless kiosk
3) Have your Costco membership card ready as it is needed during the process.
4) Tell them you are adding a new line, no other details are needed. If you are porting in a number, you will have to provide the phone number, account and PIN for the number you are porting in.
5) If your plan qualifies, they will be able to add a new line after verifying last 4 of your social and in some cases call in Tmobile for approval.
6) If you have a dual factor authentication set on account, the primary account holder will get a text message with a PIN which will be needed to complete the transaction.
7) Once this is complete, you will need to sign and date some forms to acknowledge the deal terms
8) Lastly you will be given SIM card and a copy of the paperwork confirming your new number/port.
9) Port may take a few days, so you can wait and then file for the $200 Costco promo using the directions provided on the paperwork.
10) You can then file the Tmobile promo for $100 port in new line deal.
My Costco rep knew about this deal and was knowledgeable. Hopefully my account and plans remain unchanged, time will tell.

What would hold future trade in value on future deals, the iPhone SE?
Usually, they had to call T-mobile for adding a line for me (grandfathered plan with corporate discount). She told me that she tried to add a free line this morning for other customers, but T-mobile rep said customers with corporate discount need to call directly or visit T-mobile store to add a line.
I could do September free line at Costco, but this time couldn't . Anyways wanted to share my experience today.
