SIM (3G) card cloning

I've read lot about cloning a SIM card, however i don't understand why they blabber about it being impossible.
i know what SIM card is, it's a smart card that has its own system on it and can counter attack if you try and decode it.
however what is confusing and stupid, is that none of those blabbering noobs explain, WHY is it impossible to clone a SIM byte by byte ??
just like hard drive, you can encrypt the whole hdd, but it is still possible to make exact copy of it.
ive tried looking for more info, but still nothing.
there are those "clone proof" DVDs, however even those are possible to copy and clone. DVD is different, because if original has some kind of sector that cannot be written, then you can't replicate it, but you can still emulate it after getting all data off of it. like securom and similar protection systems.

what im looking for, is hardware + software that can read every last bit of information off of SIM card, byte by byte so i can write it onto blank SIM and have a cloned SIM.

there's not much information about SIM cloning at all, there must be a reason for that, why there ain't much info about this. there are just some blabbering noobs who say no noo nooo, but no reason or explanation why it is impossible to do byte by byte clone.
they blabber about some decoding and IMSI, i don't give a shit about any of the decoding, why would i want to decode a sim before cloning ? it makes no sense at all. let it be encrypted or coded or whatever, who cares.

does anyone have more information on this? like details, why would byte by byte copy fail ?

old thread but still, I don't have any real info about this, but a wild guess would be that there isn't a "simcard reader" out there? Maybe there isn't a known way yet to extract the data of a simcard?

I got lot of stuff off the sim, but it's rather useless. Such as contacts and messages, but all the core data is not accessable.
I mean i read a lot and seems like its possible to clone only old SIMs. only the provider has the decryption keys needed to clone, but they never clone. as far as i know, they don't even keep those decryption keys or don't even have them. it's like banks send out bank cards, they never get anywhere near the PIN.
it's auto generated and no human ever sees it. it gets set automatically and letter is sealed before anyone even sees it. I assume this is what they do with SIMs, each SIM is unique, if you lose it, they can make a new one with your number, but it's not a clone of old card, cuz if you lose a card, you can ask them to block it and give you new one with same number. even tho you have 2 cards with same number, only 1 can be used.
