1. A non-subscriber identity (“non-SI”) device arranged for wireless communication in a local network according to a local communication protocol,
the local communication protocol defining protocol messages and wireless transceiving across a limited area,
the non-SI device not comprising an SI and being arranged for cooperating with a subscriber identity (“SI”) device having access to the SI,
the SI comprising subscriber identity data of a subscriber to a provider for accessing a core network, the core network providing wireless communication for mobile devices across at least a regional area,
the non-SI device comprising:
a non-SI private key constituting a pair with a non-SI public key;
a transceiver arranged for local transceiving according to the local communication protocol;
a processor arranged to execute an association sequence to establish an association with the SI, the association sequence comprising:
providing the non-SI public key to the SI device via a first communication channel, and
sharing a verification code with the SI device via a second communication channel for verifying that the SI device has obtained the non-SI public key,
wherein the first and second communication channel being different and one of the channels being an out-of-band (“OOB”) channel,
the association sequence further comprising:
providing proof of possession of the non-SI private key to the SI device via the first or the second communication channel, and
receiving, from the SI device, a certificate related to the SI and comprising a signature,
wherein the certificate enables the non-SI device to access the core network.
