Systems and methods for device state derivation are described. Some implementations include receiving, from a mobile station at a state derivation server, current connectivity characteristics of one or more radio access technologies (RATs) that are serviced by a modem of the mobile station, analyzing the one or more connectivity characteristics to determine one or more of: whether the mobile station is tuning away from a particular RAT to access another RAT or a duration for which the mobile station is tuning away from the particular RAT to access the other RAT, based on the analyzing, determining a current connectivity state of the mobile station, and displaying the current connectivity state at a user interface of a computing device associated with the state derivation server.
