Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that it is operating in a dual-subscription mode that includes a first subscription and a second subscription. In some cases, the UE may include an application that is requesting to establish a data connection in accordance with an access preference rule for the application. The UE may determine that the access preference rule lacks a match among policies of a first route selection policy associated with the first subscription (e.g., a default subscription). The UE may then evaluate a second route selection policy associated with the second subscription for a policy that matches the access preference rule based on determining the lack of the match among policies of the first route selection policy. The UE may establish the data connection after evaluating the second route selection policy for the matching policy.

Abstract: Techniques to recover from authentication failure are disclosed. During authentication of a user equipment (UE) with a public land mobile network (PLMN), the UE may receive an AUTHENTICATION REJECT with an extensible authentication protocol (EAP)-failure message. When this occurs, instead of invalidating the universal subscriber identity module (USIM) of the UE, the UE can search for other PLMNs that can potentially pass the authentication challenge. If one is found, the UE can register with the found PLMN.

Abstract: Aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method generally includes receiving a request for a wireless connection from an application associated with one or more user equipment (UE) route selection policy (URSP) rules, attempting to establish the wireless connection for the application via a first subscriber identity module (SIM) according to one or more of the URSP rules associated with the application that are supported by the first SIM, and taking one or more actions to establish the wireless connection for the application via a second SIM if the attempt to establish the wireless connection for the application via the first SIM fails.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a signal - to-noise ratio (SNR) of one or more communications from a serving cell satisfies an SNR threshold after establishing a New Radio radio resource control (RRC) connection with the serving cell. The UE may transmit a measurement message to the cell based at least in part, on the determining that the SNR of the one or more communications from the serving cell satisfies the SNR threshold. The UE may receive, from the serving cell, a list of one or more neighbor cells based at least in part on the transmitting the measurement message, and establish an RRC connection to a neighbor cell on the list based at least in part on determining that a radio link failure occurred. Numerous other aspects are provided.
