Foreword
This European Telecommunication Standard (ETS) has been produced by the Special Mobile Group
(SMG) of the European Telecommunications Standards Institute (ETSI).
This ETS defines the interface between the Subscriber Identity Module (SIM) and the Mobile Equipment
(ME) for use during the network operation phase of GSM as well as those aspects of the internal
organization of the SIM which are related to the network operation phase, within the digital cellular
telecommunications system (Phase 2/Phase 2+).
The contents of this ETS is subject to continuing work within SMG and may change following formal SMG
approval. Should SMG modify the contents of this ETS, it will be resubmitted for OAP by ETSI with an
identifying change of release date and an increase in version number as follows:
Version 5.x.y
where:
5 Indicates GSM Phase 2+ Release 1996
x the second digit is incremented for all other types of changes, i.e. technical enhancements,
corrections, updates, etc.
y the third digit is incremented when editorial only changes have been incorporated in the
specification;
NOTE: The present document includes only material relating to the 1996 release of GSM
11.11. All release 1997 material can be found in the release 6.x.y of GSM 11.11.
Transposition dates
Date of adoption of this ETS: 11 December 1998

1 Scope
This European Telecommunication Standard (ETS) defines the interface between the Subscriber Identity
Module (SIM) and the Mobile Equipment (ME) for use during the network operation phase of GSM as well
as those aspects of the internal organization of the SIM which are related to the network operation phase.
This is to ensure interoperability between a SIM and an ME independently of the respective manufacturers
and operators. The concept of a split of the Mobile Station (MS) into these elements as well as the
distinction between the GSM network operation phase, which is also called GSM operations, and the
administrative management phase are described in the GSM 02.17 [6].
This ETS defines:
- the requirements for the physical characteristics of the SIM, the electrical signals and the
transmission protocols;
- the model which shall be used as a basis for the design of the logical structure of the SIM;
- the security features;
- the interface functions;
- the commands;
- the contents of the files required for the GSM application;
- the application protocol.
Unless otherwise stated, references to GSM also apply to DCS 1800.
This ETS does not specify any aspects related to the administrative management phase. Any internal
technical reallocation of either the SIM or the ME are only specified where these reflect over the interface.
This ETS does not specify any of the security algorithms which may be used.
This ETS defines the SIM/ME interface for GSM Phase 2. While all attempts have been made to maintain
phase compatibility, any issues that specifically relate to Phase 1 should be referenced from within the
relevant Phase 1 specification.

provisions from other publications. These normative references are cited at the appropriate places in the

4 Physical characteristics
Two physical types of SIM are specified. These are the "ID-1 SIM" and the "Plug-in SIM".
The physical characteristics of both types of SIM shall be in accordance with ISO 7816-1,2 [24, 25] unless
otherwise specified. The following additional requirements shall be applied to ensure proper operation in
the GSM environment.
4.1 Format and layout
The information on the exterior of either SIM should include at least the individual account identifier and the
check digit of the IC Card Identification (see clause 10, EF ).
ICCID
4.1.1 ID-1 SIM
Format and layout of the ID-1 SIM shall be in accordance with ISO 7816-1,2 [24, 25].
The card shall have a polarization mark (see GSM 02.07 [3]) which indicates how the user should insert
the card into the ME.
The ME shall accept embossed ID-1 cards. The embossing shall be in accordance with ISO/IEC 7811 [22,
23]. The contacts of the ID-1 SIM shall be located on the front (embossed face, see ISO/IEC 7810 [21])
of the card.
NOTE: Card warpage and tolerances are now specified for embossed cards in
ISO/IEC 7810 [21].
4.1.2 Plug-in SIM
The Plug-in SIM has a width of 25 mm, a height of 15 mm, a thickness the same as an ID-1 SIM and a
feature for orientation. See figure A.1 in normative annex A for details of the dimensions of the card and
the dimensions and location of the contacts.
Annexes A.1 and A.2 of ISO 7816-1 [24] do not apply to the Plug-in SIM.
Annex A of ISO 7816-2 [25] applies with the location of the reference points adapted to the smaller size.
The three reference points P1, P2 and P3 measure 7,5 mm, 3,3 mm and 20,8 mm, respectively, from 0.
