Abstract: A wireless device may transmit, using a first SIM associated with a first radio, a first attach request to a network node and transmit, using a second SIM associated with a second radio, a second attach request to the network node. Additionally, the wireless device may receive, operating in a multiple-subscriber identity module (MSIM) mode, an attach reject message including an attach reject cause code from the network node. The wireless device may transition, based at least in part on reception of the attach reject message, the second SIM to a limited service camped state, disable one of the first radio or second radio, transition to a single-SIM mode, and communicate with the network node via the first SIM.
