Command causes the ME to return the phone book checksum <cks> stored internally . Phone book checksum is recalculated whenever there is a change in the phone book. By requesting the checksum, the external application can detect if the phone book in the ME has changed, without downloading the whole phone book.

During the SIM initialisation process, it takes some time to download the phone book from the SIM card to the ME, depending on the number of entries. In case the command is invoked before the checksum has been calculated, the ME gives an ERROR message.
