I read yet another story about SIM swap fraud in the news today.
Each SIM has an IMSI number, an international serial number. Vodacom requires access to a central database to acquire the phone number matched to this IMSI.
Does this mean that whoever is committing SIM cloning fraud is matching a cell number to a new IMSI, or a different IMSI ? If this is correct this would mean that that there are two IMSIs with the same cellphone number.
Is the above even possible ? How does this cloning work ? Is the IMSI number on the physical SIM being copied to another SIM in order to create the clones ?
