I tested it the way that post suggests, but I don’t know how to convert like they are doing here:
From the response of CSRM command: the FPLMNS are
043508 -> 405803 -> Airtel
040528 - > 405820 -> uninor
044530 -> 405034 -> unknown
04F444 -> 40444 -> Spice telecomm
The number I want to use is 20205 (vodafone) and that would be on the right side of this table. The left side is what is being used in the CRSM command. The first three lines make sense but the last one (04f444), I cannot get how it’s derived.
