Abstract
An improved core network that allows a UE to still initiate and/or receive communications via a native SIM line even if the registration of a virtual line fails is described herein. For example, the UE may include embedded virtual line settings that, when enabled, cause the UE to transmit a virtual line registration request to the core network. The core network can determine whether the UE is authorized to register a virtual line. If the UE is authorized, the core network can register a native SIM line, register the virtual line, and transmit a single message to the UE indicating that the native SIM and virtual lines are registered. If the UE is not authorized, the core network still registers the native SIM line and transmits a single message to the UE indicating that the native SIM line is registered.
