X sim and X sim Evo on ios 9

Hey guys, im new here and i apologize if i broke any rules with this thread.

I wanted to ask about x-sim evo and if its the only one able to unlock iphone 5s with v9.1? cause i asked a friend of mine to buy an x-sim capable of unlocking my iphone and the one i got doesn’t seem to do the trick. i still get "Sim Not Valid" after trying both imsi code and all modes. Any help, tricks, suggestions to a newb like me is most appreciated.
