Would this be the pertinent example?

#cred={
#	imsi="310026-000000000"
#	milenage="90dca4eda45b53cf0f12d7c9c3bc6a89:cb9cccc4b9258e6dca4760379fb82"
#}
#

And if so, in the example conf, there is this:

# milenage: Milenage parameters for SIM/USIM simulator in <Ki>:<OPc>:<SQN>
#       format


Looks like we don't really care about SQN when configuring a 'cred' section?

Thanks,
Ben
