The invention discloses a method and a device for polling configurations. The method comprises the following steps: dividing all configuration items in a terminal device into a plurality of configuration groups, and setting a corresponding configuration group change mark for each configuration group; acquiring the configuration groups having changes in the terminal device according to the configuration group change mark of each configuration group in the terminal device and the configuration group change mark of each configuration group in the terminal device stored on a network side; and synchronizing the configurations in the configuration groups having changes in the terminal device by using the configurations in the configuration groups of the terminal device stored in the network side. The configurations in the terminal device are finely divided into the configuration groups, and the rolling is performed on the configurations in the terminal device by using the configuration group as a unit, thus the rolling of the configurations on the terminal device can be achieved quickly and efficiently.
