Abstract: A technique for determining that a wireless device supports using multiple subscriber identity module (SIM) cards to establish multiple connections to wireless networks, generating a multi-SIM capability message, transmitting the multi-SIM capability message to a first wireless network; and receiving a registration accept signal in response to the multi-SIM capability message, wherein the registration accept signal indicates a first set of features supported by the first wireless network. In another aspect, a technique for a wireless system to receive, via a network interface, a multiple subscriber identity module (multi-SIM) capability message from a wireless device connected to a first wireless network; generate a registration accept signal in response to receiving the multi-SIM capability message, wherein the registration accept signal indicates a first set of features supported by the first wireless network; and send, via the network interface, the registration accept signal to the wireless device.
