Annex A (informative):
EF changes via Data Download or USAT applications

This annex defines if changing the content of an EF by the network (e.g. by sending an SMS) or by a USAT Application is advisable. Updating of certain EFs "over the air" could result in unpredictable behaviour of the UE; these are marked "Caution" in the table below. Certain EFs are marked "No"; under no circumstances should "over the air" changes of these EFs be considered.

NOTE 1: If EF_IMPI, EF_IMPU, EF_DOMAIN, P-CSCF or IMSConfigData are changed, the UICC should issue a REFRESH command. NOTE 2: If EF_UICCIARI is changed, the UICC shall issue a REFRESH command as defined in TS 31.111 [31]. The ME shall read the updated list of IARIs associated with active applications installed on the UICC.
