Can a straight talk iPhone use Tmobile?

I'm planning on getting a 5s on straight talk but can a T-mobile sim work of the phone?

No. You have to use a Straight Talk SIM card with a Straight Talk branded phone. Straight Talk may unlock the phone for you to use after a year of service with Straight Talk.

Thank you!(: The iPhone I bought today HAS A MICRO SIM CARD SLOT.
