+/**
+ * <p>Provides information for a SIM slot mapping, which establishes a unique mapping between a
+ * logical SIM slot and a physical SIM slot and port index.  A logical SIM slot represents a
+ * potentially active SIM slot, where a physical SIM slot and port index represent a hardware SIM
+ * slot and port (capable of having an active profile) which can be mapped to a logical sim slot.
+ * <p>It contains the following parameters:
+ * <ul>
+ * <li>Port index: unique index referring to a port belonging to the physical SIM slot.
+ * If the SIM does not support multiple enabled profiles, the port index is default index 0.</li>
+ * <li>Physical slot index: unique index referring to a physical SIM slot. Physical slot IDs start
+ * at 0 and go up depending on the number of physical slots on the device.
+ * This differs from the number of logical slots a device has, which corresponds to the number of
+ * active slots a device is capable of using. For example, a device which switches between dual-SIM
+ * and single-SIM mode may always have two physical slots, but in single-SIM mode it will have only
+ * one logical slot.</li>
+ * <li>Logical slot index: unique index referring to a logical SIM slot, Logical slot IDs start at 0
+ * and go up depending on the number of supported active slots on a device.
+ * For example, a dual-SIM device typically has slot 0 and slot 1. If a device has multiple physical
+ * slots but only supports one active slot, it will have only the logical slot ID 0</li>
+ * </ul>
+ *
+ * <p> This configurations tells a specific logical slot is mapped to a port from an actual physical
+ * sim slot @see <a href="https://developer.android.com/guide/topics/connectivity/telecom/telephony-ids">the Android Developer Site</a>
