This invention provides methods and systems for seamless mobile
connectivity between public and private cellular networks. The
system dynamically switches user devices between networks based on location,
radio signal availability, or preconfigured policies that prioritize private networks when within range. For devices with physical SIM cards, an embedded applet enables switching between operator profiles, while ESIM profiles deploy applets for selecting among multiple identities within a profile. All
cellular traffic, whether on public or private networks, is routed through a cloud-based
system for centralized security and
policy enforcement. Network selection may be influenced by defining the
private network as the Home
Public Land Mobile Network (HPLMN) or scanning available networks via applet capabilities. The
system supports unified subscription,
connectivity, and service management via a cloud-based portal, ensuring reliability and security across diverse network environments. This approach enhances mobility, security, and flexibility for enterprise and IoT applications.
