iPhone 5S UNLOCK TMOBILE

HELLO, I'VE AN iPHONE 5S T-MOBILE USA BLACKLISTED. I UPGRADED TO iOS8.0.2 AND MY RSIM9+ NANO CLOUD WAS WORKING PERFECTLY. NOW I CAN JUST SEE THE CARRIER INDICATOR AND 3G BUT NO BARS. IM ABLE TO USE DATA BUT NO CALLS OR SMS. IM TIRED OF RSIM9 THIS IS GIVING ME PROBLEMS SINCE iOS 7. IS THERE ANY WAY I CAN UNLOCK MY PHONE VIA IMEI?:confused::confused::confused::confused::conf used:
