Can I get an update with t-mobile if I brought an iPhone off of eBay?

Last summer I think it was I brought a iPhone 5s off of eBay and the phone is just ready to be upgraded. Can I get a upgrade with t-mobile if I brought it from eBay.

Ddd

Sure - but you'll pay extra for the upgrade. You did not buy the phone from T-Moble.

If the IMEI of the phone does not match any phone you bought through T-Mobile, it is doubtful that you can get an upgrade (trade in or turn in) with original equipment. But you can upgrade phone at any time if you are buying them.

But to be sure, just call up customer service and ask.

You'd have to call them. I don't think they will but you never know
