Claim 7:
8. A Subscriber identity (“SI”) device arranged for wireless communication with a non-SI device, the SI device having access to a 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 SI device comprising:

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:
receiving, via the first or the second communication channel, proof of possession of a non-SI private key that constitutes a pair with the non-SI public key from the non-SI device, upon successful evaluation of the received proof, obtaining a certificate related to the SI and comprising a signature as generated by a certification authority over at least part of the non-SI public key, and
transmitting the certificate to the non-SI device, the certificate enabling the non-SI device to access the core network via the local network and a gateway between the local network and the core network.
