Abstract
We describe a system for activating SI Ms, where the system comprises more SI Ms than will be authorised for use on a mobile network. The system comprises a plurality of SIMs, each of the SIMs being configured to provide a first SIM identifier. The first SIM identifiers are reused amongst said plurality of SIMs such that one of the SIMs may provide the same SIM identifier as another of the SIMs. The system includes a SIM authorisation server configured to receive the first SIM identifier from a SIM requesting activation and, in response, to provide a new SIM identifier. The new SIM identifier enables the SIM requesting activation to communicate traffic over the mobile network.
