Abstract
Apparatus and methods to access services of multiple wireless networks by a wireless device are disclosed. The wireless device attaches to a primary wireless network using a primary subscriber identity module (SIM) or electronic SIM (eSIM) via a radio access network (RAN) of the primary wireless network; establishes (i) a context for Internet Protocol (IP) network data connections using the primary SIM or eSIM and (ii) a packet data network (PDN) connection via the RAN of the primary wireless network to a gateway of a secondary wireless network using a secondary SIM or eSIM; and registers for access to services of the secondary wireless network with a server of the secondary wireless network using the secondary SIM or eSIM. The wireless device can access services of both the primary wireless network and the secondary wireless network simultaneously via the RAN of the primary wireless network.
