Hello,
I signed up with T-Mobile and purchased my phones from the wireless kiosk at Costco. The kiosk is run by a company called Wireless Advocates.
At the time I started service, I did not have my old phones available for trade-in (they were either in-use or out-of-state). The sales rep said "no problem". He said I could simply call into T-mobile to submit my telephone information and get my RMA numbers.
However, it seems that I was supposed to get the RMA numbers from the sales rep at the point-of-sale, so I'm confused.
I've visited the site www.t-mobile.com/devicetradein, and it won't let me do anything without an RMA number.
I've seen reference to a "Trade-in center" on the page "explore.t-mobile.com/cell-phone-trade-in", but there's no direct link to the trade-in center.
Any assistance would be appreciated.
