Can I use a unlocked straight talk phone on my tmobile account?

[AC Question]

I am purchasing a Samsung galaxy grand prime from a private seller. The phone is an unlocked device from straight talk. Will that work on my tmobile account and with a tmobile sim?

Welcome to Android Central! It depends on if it's a CDMA or GSM phone. What's the exact model number of the phone?
