Abstract: The present invention discloses methods and systems for providing UICC/eUICC related response information to information requests at a cellular router. The method includes receiving an information request from a wireless communication module, and determining whether a response to the information request is cached. When the response information is not cached, forwarding the information request to a massive SIM apparatus (MSA). MSA will then respond to the information request. A response based on the MSA's response will then be sent to the wireless communication module for the information request. When the response information is cached, retrieve the response information and send it to the wireless communication module.

Abstract: A method and a wireless communication device for providing communication service to devices connected to the wireless communication device. By establishing a starter wireless carrier connection using a starter SIM from a plurality of local SIMs, the wireless communication device establishes one or more logical data connections with one or more SIM banks. Remote-SIMs are selected from the one or more SIM banks and used to establish further wireless carrier connections to allow communication service to be provided to the devices over wireless carrier connections.

Abstract: The present invention discloses methods and systems for establishing data communication at a network device. The method includes identifying a cellular network by the network device. After that, the network device sends a request to an MSA for an embedded subscriber identification module (eSIM) profile of the cellular network. The MSA may or may not have an eSIM profile of the cellular network available. When an eSIM profile of the cellular network is available, the network device receives the eSIM profile information from the MSA. The network device then sends a request for data communication access to the cellular network using the eSIM profile information to obtain data communication access through the cellular network. The network device may comprise at least one universal integrated circuit card (UICC) and/or embedded universal integrated circuit card (eUICC).
