That does not completely prevent somebody from trying to connect to your
network. Using the common test equipment id and manually selecting the
network in your phone is also possible and I think much better than sending
out any operator MCC/MNC (apart from using an RF attentuator).

This code triggers the reject:

    if (!subscr)
        return gsm48_tx_mm_serv_rej(conn,
                        GSM48_REJECT_IMSI_UNKNOWN_IN_HLR);

So, have you inserted your IMSI into your OpenBSC HLR (sqlite database)?
