Call made without using Ki of the IMSI?

[Broto]

I was told that some buddies in Malaysia can make calls without cracking the Ki of the IMSI. If it is the case, we don't need to buy Dr. SIM. I wonder if it is true.

i never heard about that..
only some partials infos about radio/pc/phone materials who can interact in real time with network and 'faint' it about user/connection identity

i don't understood what u mean..
does she buy 'sort of' card who permit have calls by putting a long numbered ''prefix" before real phone number
eg : 3512#serial_number#code*06phone_number
(just an exemple
if she does, may this number are stollen or generated (in this case it's 'interesting'
if i'm in wrong way just try re-explain plz
