[Skunkworks] SAFARICOM MODEM UNLOCK CODE.

Dear All, Does anyone in the room know how to unlock this Safaricom modem to work with other providers?I have tried using YU,Orange,Zein but it keeps requesting for the unlock code. I have tried using DC-Unlocker to unlock the data card but this isn't detecting the card. Is there an alternative Software that I can use to unlock this modem? Please if anyone knows the location, send me the link. Regards, Boniface Maina.
