Yes, MS know NMO from system info (from SI13\GPRS Cell Options). When MS want to perform any mobility management procedures (e.g. Attach/Detach) and NMO=I, it should indicate to network what Type of Attach it doing in attach request (only GPRS attach, GPRS attach with already IMSI Attached or Combined GPRS / IMSI attach ).
