Abstract
A method, apparatus, and computer program product for detecting and switching between locally available PLMNs accessible to a user equipment based on a Preferred PLMN List and a Network Slice Aware PLMN Exceptions List configured by a HPLMN. The user equipment connects to a preferred VPLMN. The user equipment determines that a particular network function is not supported by the connected preferred VPLMN. The user equipment determines that another VPLMN is required to support the particular network function. The user equipment then switches to a non-preferred VPLMN which supports the particular network function. Once the particular network function is no longer necessary for the user equipment to perform a required task, the user equipment switches back a preferred VPLMN.
