Hey,

Later, a GET RESPONSE is issued from ME to SIM to obtain the SRES + Kc values, and this is where we can delay with waiting time extension (0x60) until we have the result.

and maybe to make this more clear. The 0x60 will not be transmitted by the remote SIM but by the card emulation firmware. The expiration of a hardware timer will lead to "tc_etu_wtime_half_expired" being called and if the states are right the 0x60[1] will be transmitted.
