because rep wanted to call T-Mobile to make sure it's free. That took a while... Plus agent is new so need constant help from better knowledge rep. Funny thing is, after me, everyone came in just to add a line and Costco agent no longer need to call T-Mobile to verify. So their is much faster ....
I have T-Mobile ONE - and this is my 12th line.
I just hope the new agent enter the correct info on the rebate. One line says "activated permanent phone #" but he entered my main account existing tel#..... not the newly activated number.

I did one new line at a store and one using tforce. No issues.
First, I verified that my rate plan qualified.
Then went to Costco (when it just opened, so was first in line.) The guy was sort of new and wasn't familiar with the "add a line free" deal. No biggie - I just asked him to add a BYOD line anyways to take advantage of the $200 shop card. Probably took about 30 mins since he had to get his manager to help enter it in.
When I got back home, I called T-mobile CS and they were able to confirm this newly added line is free.
Weighing whether it's worth the trouble to try for the $100 port-in rebate. Anyways, at least the $200 was fairly easy.
1 - Go to Costco with an unlocked phone.
2 - Ask the rep to activate it.
3 - While at Costco call Tmobile and get the free line activated.
4 - Give the info about the free line you just got to the Costco rep.
5 Then you get the 200 from Costco - in a gift card - sent in a couple of weeks.
As long as your plan qualifies, you havent cancelled a line in the last 90 days, and have 2 post paid lines active... this line from Costco will get registered as ' This one on us'
Done!

I bought used phones and they are lost in the mail. I can't get the IMEIs yet. Can I walk in with a unlocked wiped simless current phone and get the deal?
(I don't care which sim is in which phone while I wait for $200)
TIA
