Issue Description
COTS UE (Samsung Galaxy) with MCC 001 and MNC 01 and IMSI 001010000000037 is unable to register on the srsRAN 4G. The log of srsepc shows: User not in HSS. IMSI: 001010000000037 User not found. IMSI: 001010000000037 I have manually edited the user_db.csv with ue details which include: IMSI, Key, OPC of the SIM card, however, I keep getting same error message in the log of srsepc. I am unable to get any headway and am stuck at this step. Please guide me to resolve the issue as I am required to carry out further trials of srsRAN.
