No SIM on GTA02

Hi folks.

Running layer1 (no TX) on GTA02 with host applications compiled for GTA02
also. Layer1 seems not able to communicate with SIM card, and so no IMSI
etc. Mobile enters in "emergency calls only" mode. Simtest firmware also
fails.

SIM and phone hardware is checked working with fsogsmd.

I cannot find any configure switch to disable/enable SIM, and it has no
sense on simtest firmware anyway.

Has anything to do with this note on sim.h and the fact that on GTA02 you
should cycle the baseband power after osmocon start for romloader to begin?
/* Known Bugs:
   1.) After powering down the simcard communication stops working
*/

On the other hand, on GTA02 osmocon or romloader doesn't start if battery is
not attached. Keeps staying on "Sending beacon".
