Abstract
A user equipment (UE) includes multiple subscriber identification module (SIM) cards to connect to different networks, including any available opportunistic data network. To support connection to 5G opportunistic data networks, the UE employs the primary network stack (the network stack associated with the primary SIM card) to connect to a 5G communications network (e.g., a 5G cellular network), and further employs the primary network stack to periodically scan for opportunistic data networks. In response to detecting a 5G opportunistic data network, the primary network stack transfers the 5G connection capability to a secondary network stack (a network stack associated with a secondary SIM card), and the UE connects to the 5G opportunistic data network via the secondary network stack, while connecting the primary network stack to another communications network (e.g., a Long-Term Evolution (LTE) or 4G communications network). The UE is thereby able to detect and connect to 5G opportunistic data networks, even when only one of the multiple SIM cards is able to have 5G capability at one time.
