Annex P (normative):
Support of USAT by Terminals with reduced feature capabilities.

See ETSI TS 102 223 [32] Annex S except for USAT-specific commands which are defined as follows.

Table P.1 provides the applicability of USAT-specific envelope commands for the different terminal types.

Table P.2 provides an overview of USAT-specific affected commands.

Table P.1: Envelope applicability table

Envelope	ND type	NK type	NA type	NS type	NL type
SMS-PP data download
Cell Broadcast data download
Call Control by USIM	Note 2
MO Short Message Control by USIM	Note 2
EVENT DOWNLOAD – (I-)WLAN Access status
EVENT DOWNLOAD – Network Rejection
USSD Data Download
Geographical Location Reporting
ProSe Report
Note 1: "O" means proactive command is optional, No indication means that the proactive command is fully applicable. Note 2: If an alpha identifier is provided by the UICC in the response, it shall be ignored by the terminal.

Table P.2: Overview of affected commands

Command	ND type	NK type	NA type	NS type	NL type
SEND SS	partial
SEND USSD – MMI Mode	partial
SEND USSD – Application Mode	partial
OPEN CHANNEL related to (I-)WLAN bearer	partial
Geographical Location Request	partial
Note: "O" means support of this command is optional, "partial" means parts of the command are affected. No indication means that the proactive command is fully applicable.

Annex Q (normative):
Default routing for USAT over AT interface
