I cant say because i have never even seen that uscell variant, if i can get one i could tell you,but you kinda of contradict yourself in what you just said,if you know its cdma only then why you wish to use gsm? but if it has a sim slot and its uscell seems to me that its at least cdma and lte and probly cdma,lte and gsm like the other vzw one,i can unlock most modems but like i said i have never seen that one before so i dont know for sure.
