Abstract
The present invention discloses methods and systems for using one or more substitute connections between a cellular router and a server. When the server detects that one or more connections fail, the server starts using one or more substitute connections to the one or more failed connections. The connections are used to transmit requests and responses between the cellular router and the server. The requests comprise authentication requests that are transmitted to the server from the cellular router. The responses comprise authentication responses that are transmitted to the cellular router from the server. The authentication requests and the authentication responses are to authenticate one or more SIM cards housed in the server. The cellular router authenticates the one or more SIM cards by utilizing the authentication responses to keep maintaining respective cellular connections established using the one or more SIM cards from the server.
