Why you can't get what you want is here:

GSM algorithms subject to application

The following example A3/A8 algorithm specifications are available to
qualified industry parties (GSM network operators and manufacturers of
eligible GSM equipment) on application to the GSM Association: COMP128

COMP128-2
COMP128-3

Application packs for the above algorithms can be requested from
security@gsm.org. A per-copy fee of EUR2,000 is chargeable to non-members
of the GSM Association wishing to receive these algorithm specifications.
