set echo true

# this script will deactivate all IMS related services and files.  This can be used
# in case you do not wish to use any IMS services, or you do not wish to configure
# the IMS specific files on the USIM/ISIM cards.  The card will then behave like a 3G USIM
# without any IMS capability, using the default fall-back mechanisms specified by 3GPP.

# TODO: add your card-specific ADM pin at the end of the verify_adm line below
