A method to access services of multiple wireless networks (310A, 310B) by a wireless device, the method comprising: by the wireless device: detecting establishment of a voice connection via a radio access network,RAN, of a second wireless network using a non-data-preferred subscriber identity module,SIM, or electronic SIM,eSIM, of the wireless device; responsive to the detecting the establishment of the voice connection: establishing a context for Internet Protocol,IP, network data connections via the non-data-preferred SIM or eSIM; when a wireless local area network, WLAN, connection is unavailable, establishing a tunneled packet data network,PDN, connection via the RAN of the second wireless network to a gateway of a first wireless network associated with a data-preferred SIM or eSIM of the wireless device; and registering for access to services of the first wireless network with a server of the first wireless network using the data-preferred SIM or eSIM via the tunneled PDN connection; and responsive to detecting termination of the voice connection: terminating the context for IP network data connections via the non-data-preferred SIM or eSIM; and establishing a second context for IP network data connections via the data-preferred SIM or eSIM wherein the wireless device comprises a single-radio, multiple SIM wireless device that does not support two or more active voice connections via two or more different radio access networks (312A, 312B) of two or more cellular wireless networks (310A, 310B) at the same time. detecting establishment of a voice connection via a radio access network,RAN, of a second wireless network using a non-data-preferred subscriber identity module,SIM, or electronic SIM,eSIM, of the wireless device; responsive to the detecting the establishment of the voice connection: establishing a context for Internet Protocol,IP, network data connections via the non-data-preferred SIM or eSIM; when a wireless local area network, WLAN, connection is unavailable, establishing a tunneled packet data network,PDN, connection via the RAN of the second wireless network to a gateway of a first wireless network associated with a data-preferred SIM or eSIM of the wireless device; and registering for access to services of the first wireless network with a server of the first wireless network using the data-preferred SIM or eSIM via the tunneled PDN connection; and establishing a context for Internet Protocol,IP, network data connections via the non-data-preferred SIM or eSIM; when a wireless local area network, WLAN, connection is unavailable, establishing a tunneled packet data network,PDN, connection via the RAN of the second wireless network to a gateway of a first wireless network associated with a data-preferred SIM or eSIM of the wireless device; and registering for access to services of the first wireless network with a server of the first wireless network using the data-preferred SIM or eSIM via the tunneled PDN connection; and responsive to detecting termination of the voice connection: terminating the context for IP network data connections via the non-data-preferred SIM or eSIM; and establishing a second context for IP network data connections via the data-preferred SIM or eSIM wherein the wireless device comprises a single-radio, multiple SIM wireless device that does not support two or more active voice connections via two or more different radio access networks (312A, 312B) of two or more cellular wireless networks (310A, 310B) at the same time. terminating the context for IP network data connections via the non-data-preferred SIM or eSIM; and establishing a second context for IP network data connections via the data-preferred SIM or eSIM wherein the wireless device comprises a single-radio, multiple SIM wireless device that does not support two or more active voice connections via two or more different radio access networks (312A, 312B) of two or more cellular wireless networks (310A, 310B) at the same time.
