1. A method, comprising:
receiving a notification of a network loss from a mobile communication network, the notification comprising a current network loss cause;
selecting a network loss event duration estimate among a plurality of network loss event duration estimates stored on an integrated circuit card and indexed according to a corresponding plurality of network loss cause indices;
selecting a stored profile of a plurality of stored profiles on the integrated circuit card based on the selected network loss event duration estimate, wherein the plurality of stored profiles are associated with user subscriptions; and
attaching to the mobile communication network using the selected stored profile when the selected stored profile is not already enabled.
