Claim 1:
2. The apparatus of claim 1, wherein the authenticated access mode per PLMN is selected from a group comprising only authenticated access allowed, un-authenticated access approval required, and disable, and wherein the processor is further configured to:
if the authenticated access mode is disable, determine that the cell authentication is successful;
if the cellular cell does not support the authenticated access feature and a corresponding primary PLMN authenticated access mode is only authenticated access allowed, determine that the cell authentication fails;
if the cellular cell does not support the authenticated access feature and the corresponding primary PLMN authenticated access mode is un-authenticated access approval required, generate a first request, to a primary PLMN of the cellular network, for un-authenticated access approval; and
if the cellular cell supports the authenticated access feature and the corresponding primary PLMN authenticated access feature mode is not disable, attempt a first authentication process to verify a cellular cell public key using a cellular network public key and authentication codes broadcast by the cellular cell.
