Little help on UNLOCKING -Reliance Netconnect Broadband + HUAWEI EC150

Hey fellas., i really need some help over here -- I'm trying to unlock the Reliance Net connect Broadband + (HUAWEI EC 150) -- actually several devices are out there in market followed by different unlocking methods and tools., But the problem is i couldn't found any sort of success approach on net for this particular modem., i have UNLOCKED other data cards before so it's not a big deal now.,

- I have used MDMA but it's not recognizing the device.

- Bitpim - Doesn't work for EC 150.

- CDMA workshop -A very good tool but i don't have any accurate steps to follow UP. (AND i'm still reading memory)

- Universal Master Code - Useless if i don't have correct IMEI no., actually doesn't support HUAWEI EC150

It's the older card and i hope if somebody have unlocked it then please help me here., IMEI is not printed on device like some other devices have and nothing else is there in safety box., i just need to find out the correct IMEI no. or UNLOCK CODE and SPC CODE., details of the card are below.
