Will a new att iphone 5c work on tmobile?

If I buy an att iphone 5c off of ebay will it work on tmobile? I would be paying full price.

I don't know if it has a SIM card slot, but go ahead and put the T-Mobile SIM in, reboot the iPhone and wait an hour or so. It should say congratulations, your iPhone is unlocked. If it immediately asks for a pincode enter it. Hope it works.
