GSM 900 and DCS 1800.

In the mobile configuration (mobile.cfg) you should see
these lines "p-gsm", "e-gsm", "dcs", in the support section
without the "no" in front of them.

This seems to be the real problem. Your SIM is not responding
to the firmware and the mobile cannot connect to any network.
You can try to apply the patch created by Lukas. It was attached
to the post "patches for SIM in the firmware" in list.

Cheers,
