A device can receive, using an application policy handler (APH) component included in the device, a request for a data session for an application associated with the device. The device can identify, using the APH component included in the device, a user equipment route selection policy (URSP) rule, associated with the application, included in a URSP. The device can identify, using the APH component, a network slice specified by the URSP rule associated with the application and a data network specified by the URSP rule associated with the application. The device can attempt, using a modem component included in the device, to establish the data session using the network slice specified by the URSP rule associated with the application and the data network specified by the URSP rule associated with the application.
