SGSN / GMM: Only allow non-roaming IMSIs As we do not yet use the HLR from the SGSN, we allow all MS to attach to our GPRS network. However, if this is running in a public environment, it could cause service interruption to users of commercial GPRS networks. Thus, we now check if the first 5 digits of the IMSI match the MCC/MNC of the cell that they want to register to. Thus, any subscribers with SIM cards from real operators will no longer be accepted.
