I did wonder about that - in EAP-SIM terms, the identity is the
IMSI number and it should be up to the client to read it off the
Sim.

I tried putting identity="imsi number" into the config and it did
cause the client to generate a Response message to the authenticator,
containing the IMSI.

Debug output looks like this:
