I'm sorry but you cannot unlock your sim card. Your phone is a US Cellular phone.
Your phone use only 4G LTE US (CDAM) not European (GSM)

DM mode is Diagnostic Mode. This is the mode you need the phone in when you are using flashing software (CDMA workshop, DFS, etc). I also found that *#0808# will work on this phone to switch to DM + Modem + ADB

^^in case anyone else is scouring the net looking for that info..lol
