Costco Verizon and AT&T customers with older phones on installment switch to T-Mobile and get $200 BYOD + $450 payoff per line YMMV
Thumb Score: 0
The current BYOD promo at Costco is $200 per line. You qualify as long as you bring a new device from any carrier and use it on one of T-Mobile's unlimited plans. (This is offered by Costco Kiosks).
You can double dip this promotion with their carrier freedom promo where they pay off $450 per line up to five lines as long as you have a device that has been on an installment plan for a minimum of 90 days and on their list of approved devices from Verizon or ATT. (
This deal is NOT offered by Costco Kiosks you have to do this on your own after you switch).
