System(s) and method(s) are provided for management of content in a mobile device. Content can be firmware associated with mobile functionalities, or data a mobile can process. To effect a content update, a first network platform that serves a multimode mobile device through a first radio access network (RAN) can facilitate establishment of an end-to-end tunnel to the multimode through a second RAN associated with a second network platform; the first network platform can then push the content update to the multimode mobile through the second RAN. Typically the second RAN employs a distinct radiofrequency band than the first RAN; thus the content update is offloaded from traffic in the first wireless network. Content updates can be signaled through the first RAN and implemented upon end-to-end tunnel establishment to the first network platform through the second RAN. Moreover, said updates can be scheduled according to a network-configured subscriber update profile.
