A user of a device is provided with a notification indicating an estimate of a probability of success of a call on a cellular network prior to originating the call. With this notification the user may be aware that the device is in an area where the call may not be successfully connected, or the call may be disconnected due to the signaling conditions. The user then may elect to either continue attempting to establish the call, or to delay the call until the user is in a location more likely to lead to successful call origination.
