Methods and apparatus for accessing services of multiple wireless networks via a single radio access network

A wireless device configured for access to services of a secondary wireless network via a radio access network of a primary wireless network, the wireless device comprising:

• wireless circuitry configurable to communicate via a first wireless access network;
• one or more processors communicatively coupled to the wireless circuitry;
• and
• a memory communicatively coupled to the one or more processors,
• wherein the one or more processors are configured to execute instructions stored in the memory to cause the wireless device to:
• attach to the primary wireless network using a primary electronic subscriber identity module (eSIM) via a radio access network (RAN) of the primary wireless network;
• establish a context for Internet Protocol (IP) network data connections using the primary eSIM;
• establish a packet data network (PDN) connection via the RAN of the primary wireless network to a gateway of the secondary wireless network using a secondary SIM or eSIM;
• register for access to services of the secondary wireless network with a server of the secondary wireless network using the secondary SIM or eSIM;
• and
• access the services of the secondary wireless network via the RAN of the primary wireless network.

An apparatus configurable for operation in a wireless device, the apparatus comprising:

• one or more processors communicatively coupled to a memory storing instructions that when executed cause the wireless device to:
• attach to a primary wireless network using a primary electronic subscriber identity module (eSIM) of an embedded universal integrated circuit card (eUICC) via a radio access network (RAN) of the primary wireless network;
• establish a context for Internet Protocol (IP) network data connections using the primary eSIM;
• establish 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 of a removable universal integrated circuit card (UICC);
• register for access to services of the secondary wireless network with a server of the secondary wireless network using the secondary SIM;
• and
• access services of the secondary wireless network via the RAN of the primary wireless network.
