Hello,

I am decoding GMM_IDENTITY_REQUEST and it always shows GMM Cause with cause = Illigal MS .

raw data = Buffer 0000 - 000F 08 15 03

Decode output:

Message Content GSM A-I/F DTAP - Identity Request Protocol Discriminator: GPRS mobility management messages (8) .... 1000 = Protocol discriminator: GPRS mobility management messages (0x08) 0000 .... = Skip Indicator: No indication of selected PLMN (0) DTAP GPRS Mobility Management Message Type: Identity Request (0x15) GMM Cause GMM Cause: Illegal MS (3)
