Hi Neetesh,

Can anyone please tell me what is the GSM frequency band for Europe (Germany)?

GSM 900 and DCS 1800.

Do I need to enable such band before working on OsmocomBB ?

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.

I have uploaded the mobile layer1 onto phone but I am still not able to read the SIM. The message I got is ms 1 is down and radio is not started.

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,

LM
