Default [Q] [HELP NEEDED] 'Not registered on network' error message

Hey everyone, my carrier is Straight Talk using SIM. I was using my Samsung Galaxy S3 up until the phone started to fail. I just transfer over my sim card over to my S4. Both are T-Mobile phones. For some reason when I try to make calls I get an error message stating "Not register on network". I even tried to unlock and root my phone, but I am not savvy to attempt anything further without help. I am not sure what the problem is, but the phone is in new condition. It is either the service or the OS of the phone. Can anyone help me?

Either your device is blacklisted or depending how straight talk works, your device may not be on your account.. How did you purchase the device?
