Hi, I am a new user to osmocom. I am getting the following error: OsmocomBB# show ms 1 MS '1' is down, radio is not started IMEI: 000000000000000 IMEISV: 0000000000000000 IMEI generation: fixed automatic network selection state: A0 null cell selection state: C0 null radio ressource layer state: idle mobility management layer state: MM idle, PLMN search OsmocomBB# show subscriber 1 Mobile Subscriber of MS '1': IMSI: Status: U2_NOT_UPDATED IMSI detached LAI: invalid Access barred cells: no Access classes: can anyone tell me the solution what is the exact problem. I have also tried this one: "enable" -> "conf t" -> "ms 1" -> "no shutdown" and make "write" the config. Please help me. I am also using C118 phone in Germany. regards, Neetesh Get your own FREE website, FREE domain & FREE mobile app with Company email.  Know More >
