Methods, systems, and devices for wireless communications are described. A source user equipment (UE) may determine which subscriber identity module (SIM) card to use based on information of the target UE. For example, the target UE may have poor call quality using a first SIM, but high call quality when using a second SIM. The target UE may indicate the call quality for each SIM in subscription information to the source UE. The source UE may determine to use the second SIM of the target UE instead of the first SIM, resulting in higher call quality for the target UE. The subscription information may include a variety of information related to the target UE, such as subscriptions of the target UE, RAT availabilities for the target UE, etc. The target UE may also configure settings for receiving or rejecting data calls. The target UE may configure whether to receive data calls based on connectivity parameters.
