Foreword
This Technical Specification has been produced by the 3rd Generation Partnership Project (3GPP).
The contents of the present document are subject to continuing work within the TSG and may change following formal
TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an
identifying change of release date and an increase in version number as follows:
Version x.y.z
where:
x the first digit:
1 presented to TSG for information;
2 presented to TSG for approval;
3 or greater indicates TSG approved document under change control.
y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
updates, etc.
z the third digit is incremented when editorial only changes have been incorporated in the document.
In the present document, modal verbs have the following meanings:
shall indicates a mandatory requirement to do something
shall not indicates an interdiction (prohibition) to do something
The constructions "shall" and "shall not" are confined to the context of normative provisions, and do not appear in
Technical Reports.
The constructions "must" and "must not" are not used as substitutes for "shall" and "shall not". Their use is avoided
insofar as possible, and they are not used in a normative context except in a direct citation from an external, referenced,
non-3GPP document, or so as to maintain continuity of style when extending or modifying the provisions of such a
referenced document.
should indicates a recommendation to do something
should not indicates a recommendation not to do something
may indicates permission to do something
need not indicates permission not to do something
The construction "may not" is ambiguous and is not used in normative elements. The unambiguous constructions
"might not" or "shall not" are used instead, depending upon the meaning intended.
can indicates that something is possible
cannot indicates that something is impossible
The constructions "can" and "cannot" are not substitutes for "may" and "need not".
will indicates that something is certain or expected to happen as a result of action taken by an agency
the behaviour of which is outside the scope of the present document
will not indicates that something is certain or expected not to happen as a result of action taken by an
agency the behaviour of which is outside the scope of the present document
might indicates a likelihood that something will happen as a result of action taken by some agency the
behaviour of which is outside the scope of the present document
ETSI
3GPP TS 31.130 version 18.2.0 Release 18 5 ETSI TS 131 130 V18.2.0 (2025-01)
might not indicates a likelihood that something will not happen as a result of action taken by some agency
the behaviour of which is outside the scope of the present document
In addition:
is (or any other verb in the indicative mood) indicates a statement of fact
is not (or any other negative verb in the indicative mood) indicates a statement of fact
The constructions "is" and "is not" do not indicate requirements.

5 File Access API
The (U)SIM file access API consists of the package uicc.usim.access. This package defines additional constants to those
defined in the uicc.access package from ETSI TS 102 241 [2]. The access to the file system, defined in TS 51.011 [4]
and TS 31.102 [3], is the one specified in ETSI TS 102 241 [2] via the UICC FileView Interface. When selecting a
cyclic file the current record number is defined, this applies also to files located under DF .

6 (U)SAT Framework
6.0 Overview
The (U)SIM toolkit API consists of the uicc.usim.toolkit package for toolkit features defined in TS 31.111 [7] and
TS 51.014 [8], and is based on the uicc.toolkit package defined in ETSI TS 102 241 [2].

6.1 Applet triggering
See ETSI TS 102 241 [2].
6.1.1 Exception Handling
The following clause describes the handling of exceptions by the (U)SAT Framework in addition to the behaviour
defined in ETSI TS 102 241 [2] for the CAT Runtime Environment.
If an Applet triggered by EVENT_FORMATTED_SMS_PP_ENV event throws an ISOException with the reason code
(0x6FXX), it shall be sent to the terminal.
Other Exceptions shall not be propagated to the terminal.
6.2 Definition of Events
The following events can trigger a Toolkit Applet in addition to the events defined in ETSI TS 102 241 [2], all short
values are reserved in ETSI TS 102 241 [2]:

There are two ways for a card to receive a Short Message Point to Point: via an ENVELOPE(SMS-PP DOWNLOAD)
APDU as defined in TS 31.111 [7] and TS 51.014 [8] or an UPDATE RECORD EF APDU as defined in
SMS
TS 31.102 [3] and TS 51.011 [4]. The EF can be either located under the DF or under any ADF as defined in
SMS Telecom
TS 31.102 [3] and TS 51.011 [4].
The received Short Message may be:
- formatted according to TS 31.115 [9] or an other protocol to identify explicitly the toolkit applet for which the
message is sent;
- unformatted (e.g. a toolkit applet specific protocol ) then the (U)SAT Framework will pass this data to all
registered toolkit applets.
ETSI
3GPP TS 31.130 version 18.2.0 Release 18 10 ETSI TS 131 130 V18.2.0 (2025-01)
When the Short Message is received as Concatenated Short Messages as defined in TS 23.040 [10], it is the
responsibility of the (U)SAT Framework to link single Short Messages together to re – assemble the original message
before any further processing. The original Short Message shall be placed in one SMS TPDU TLV (with TP-UDL field
coded on one octet) included in the USATEnvelopeHandler. The concatenation control headers used to re-assemble the
short messages in the correct order shall not be present in the SMS TPDU. The TP-elements of the SMS TPDU and the
Address (TS – Service-Centre-Address) shall correspond to the ones in the last received Short Message (independently
of the Sequence number of Information-Element-Data).
The minimum requirement for the (U)SAT Framework is to process a concatenated short message with the following
properties:
- the Information Element Identifier is equal to the 8-bit reference number.
- it contains uncompressed 8 bit data or uncompressed UCS2 data.
EVENT_FORMATTED_SMS_PP_ENV
Upon reception of a TS 31.115 [9] formatted Short Message Point to Point (Single or Concatenated) via an
ENVELOPE, the (U)SAT Framework shall:
- verify the security of the Short Message as per TS 31.115 [9];
- trigger the toolkit applet registered with the corresponding TAR;
- take the optional Application Data posted by the triggered toolkit applet if present;
- secure and send the response packet using SMS-DELIVER-REPORT or SMS-SUBMIT.
When the toolkit applet is triggered, data shall be provided deciphered.
EVENT_UNFORMATTED_SMS_PP_ENV
Upon reception of an unformatted Short Message Point to Point (Single or Concatenated) via an ENVELOPE, the
(U)SAT Framework shall trigger all the Toolkit Applets registered to this event.
NOTE 1: As a consequence of the EnvelopeResponseHandler availability rules specified in clause 6.6, only the first
triggered toolkit applet is guaranteed to be able to send back a response.
EVENT_FORMATTED_SMS_PP_UPD
Upon reception of a TS 31.115 [9] formatted Short Message Point to Point (Single or Concatenated) via an UPDATE
, the (U)SAT Framework shall:
RECORD EFSMS
- update the EF file with the data received, it is then up to the receiving toolkit applet to change the SMS stored
SMS
in the file (i.e. the toolkit applet need to have access to the EFSMS file)
- verify the security of the Short Message as per TS 31.115 [9];
- convert the UPDATE RECORD EF APDU into a COMPREHENSION TLV List;
SMS
- trigger the toolkit applet registered with the corresponding TAR;
When the toolkit applet is triggered, data shall be provided deciphered.
The USATEnvelopeHandler provided to the applet shall:
- return BTAG_SMS_PP_DOWNLOAD to the getTag() method call;
- return the Comprehension TLV list length to the getLength() method call;
The USATEnvelopeHandler provided to the applet shall contain the following COMPREHENSION TLVs:
- Device Identities TLV
The Device Identities Comprehension TLV is used to store the information about the absolute record number in the
EF file and the value of the EF record status byte, and is formatted as defined below:
SMS SMS
ETSI
3GPP TS 31.130 version 18.2.0 Release 18 11 ETSI TS 131 130 V18.2.0 (2025-01)

length = 02
Absolute Record Number
Record Status
With the absolute record number the toolkit applet can update EF in absolute mode to change the received SMS (e.g.
