Foreword
This European Telecommunication Standard (ETS) has been produced by the Special Mobile Group
(SMG) Technical Committee (TC) of the European Telecommunications Standards Institute (ETSI).
This ETS specifies the Subscriber Identity Module (SIM) to Mobile Equipment (ME) interface within the
European digital cellular telecommunications system (Phase 2).
This ETS corresponds to GSM technical specification, GSM 11.11 version 4.15.0 version.
The specification from which this ETS has been derived was originally based on CEPT documentation,
hence the presentation of this ETS may not be entirely in accordance with the ETSI/PNE rules.
Reference is made within this ETS to GSM Technical Specifications (GSM-TS) (note).
NOTE: TC-SMG has produced documents which give the technical specifications for the
implementation of the European digital cellular telecommunications system. Historically,
these documents have been identified as GSM Technical Specifications (GSM-TS).
These TSs may have subsequently become I-ETSs (Phase 1), or ETSs (Phase 2),
whilst others may become ETSI Technical Reports (ETRs). GSM-TSs are, for editorial
reasons, still referred to in current GSM ETSs.

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 organisation 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 Technical Specification 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 realisation 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.

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 [23 24] 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 [23 24].
The card shall have a polarisation mark (see TS 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 7811 [21, 22].
The contacts of the ID-1 SIM may be located on either the front (embossed face, see ISO 7810 [20]) or
the back of the card.
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 [23] do not apply to the Plug-in SIM.

Page 14
ETS 300 608: January 1996 (GSM 11.11 version 4.15.0 version)
Annex A of ISO 7816-2 [24] 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.
The values in Table A.1 of ISO 7816-2 [24] are replaced by the corresponding values of figure A.1.
4.2 Temperature range for card operation
The temperature range for full operational use shall be between -25°C and +70°C with occasional peaks of
up to +85°C. "Occasional" means not more than 4 hours each time and not over 100 times during the life
time of the card.
4.3 Contacts
4.3.1 Provision of contacts
ME: There shall not be any contacting elements in positions C4 and C8. Contact C6 need not be
provided for Plug-in SIMs.
SIM: Contacts C4 and C8 need not be provided by the SIM. Contact C6 shall not be bonded in the SIM
for any function other than supplying Vpp.
4.3.2 Activation and deactivation
The ME shall connect, activate and deactivate the SIM in accordance with the Operating Procedures
specified in ISO/IEC 7816-3 [25].
For any voltage level, monitored during the activation sequence, or during the deactivation sequence
following soft power-down, the order of the contact activation/deactivation shall be respected.
NOTE 1: Soft Power switching is defined in TS GSM 02.07 [3].
NOTE 2: It is recommended that whenever possible the deactivation sequence defined in
ISO/IEC 7816-3 [25] should be followed by the ME on all occasions when the ME is
powered down.
If the SIM clock is already stopped and is not restarted, the ME is allowed to deactivate all the contacts in
any order, provided that all signals reach low level before Vcc leaves high level. If the SIM clock is already
stopped and is restarted before the deactivation sequence, then the deactivation sequence specified in
ISO/IEC 7816-3 [25] subclause 5.4 shall be followed.
When Vpp is connected to Vcc, as allowed by GSM (see clause 5), then Vpp will be activated and
deactivated with Vcc, at the time of the Vcc activation/deactivation, as given in the sequences of ISO/IEC
7816-3 [25] subclauses 5.1 and 5.4.
The voltage level of Vcc, used by GSM, differs from that specified in ISO/IEC 7816-3 [25]. Vcc is powered
when it has a value between 4,5 V and 5,5 V.
4.3.3 Inactive contacts
The voltages on contacts C1, C2, C3, C6 and C7 of the ME shall be between 0 and ± 0,4 volts referenced
to ground (C5) when the ME is switched off with the power source connected to the ME. The
measurement equipment shall have a resistance of 50 kohms when measuring the voltage on C2, C3, C6
and C7. The resistance shall be 10 kohms when measuring the voltage on C1.
4.3.4 Contact pressure
The contact pressure shall be large enough to ensure reliable and continuous contact (e.g. to overcome
oxidisation and to prevent interruption caused by vibration). The radius of any curvature of the contacting
elements shall be greater than or equal to 0,8 mm over the contact area.
Under no circumstances may a contact force be greater than 0,5 N per contact.

4.4 Precedence
For Mobile Equipment, which accepts both an ID-1 SIM and a Plug-in SIM, the ID-1 SIM shall take
precedence over the Plug-in SIM (see TS GSM 02.17 [6]).
4.5 Static Protection
Considering that the SIM is a CMOS device, the ME manufacturer shall take adequate precautions (in
addition to the protection diodes inherent in the SIM) to safeguard the ME, SIM and SIM/ME interface
from static discharges at all times, and particularly during SIM insertion into the ME.
5 Electronic signals and transmission protocols
Electronic signals and transmission protocols shall be in accordance with ISO/IEC 7816-3 [25] unless
specified otherwise. The following additional requirements shall be applied to ensure proper operation in
the GSM environment.
The choice of the transmission protocol(s), to be used to communicate between the SIM and the ME, shall
at least include that specified and denoted by T=0 in ISO/IEC 7816-3 [25].
The values given in the tables hereafter are derived from ISO/IEC 7816-3 [25], subclause 4.2 with the
following considerations:
-V and V always refer to the device (ME or SIM) which is driving the interface. V and V
OH OL IH IL
always refer to the device (ME or SIM) which is operating as a receiver on the interface.
- This convention is different to the one used in ISO/IEC 7816-3 [25], which specifically defines an
ICC for which its current conventions apply. The following clauses define the specific core
requirements for the SIM, which provide also the basis for Type Approval. For each state (V , V ,
OH IH
V and V ) a positive current is defined as flowing out of the entity (ME or SIM) in that state.
IL OL
- The high current options of ISO/IEC 7816-3 [25] for V and V are not specified for the SIM as
IH OH
they apply to NMOS technology requirements. No realisation of the SIM using NMOS is foreseen.
5.1 Supply voltage Vcc (contact C1)
The SIM shall be operated within the following limits:
Table 1: Electrical characteristics of Vcc under normal operating conditions
Symbol Minimum Maximum Unit
Vcc 4,5 5,5 V
Icc 10 mA
The current consumption of the SIM shall not exceed the value given in table 1 at any frequency accepted
by the SIM.
When the SIM is in idle state (see below) the current consumption of the card shall not exceed 200 μA at 1
MHz and 25°C.
The ME shall source the maximum current requirements defined above. It shall also be able to counteract
spikes in the current consumption of the card up to a maximum charge of 40 nAs with no more than 400 ns
duration and an amplitude of at most 200 mA, ensuring that the supply voltage stays in the specified range.
NOTE: A possible solution would be to place a capacitor (e.g. 100 nF, ceramic) as close as
possible to the contacting elements.

5.2 Reset (RST) (contact C2)
The ME shall operate the SIM within the following limits:
Table 2: Electrical characteristics of RST under normal operating conditions
Symbol Conditions Minimum Maximum
V I = +20μA Vcc-0,7 Vcc (note)
OH OHmax
V I = -200 μA 0V (note) 0,6V
OL OLmax
t t C = C = 30pF 400μs
R F out in
NOTE: To allow for overshoot the voltage on RST shall remain
between -0,3V and Vcc+0,3V during dynamic operation.
5.3 Programming voltage Vpp (contact C6)
SIMs shall not require any programming voltage on Vpp. The ME need not provide contact C6. If the ME
provides contact C6, then, in the case of the ID-1 SIM the same voltage shall be supplied on Vpp as on
Vcc, while in the case of Plug-in SIMs the ME need not provide any voltage on C6. Contact C6 may be
connected to Vcc in any ME but shall not be connected to ground.
5.4 Clock CLK (contact C3)
The SIM shall support 1 to 5 MHz. The clock shall be supplied by the ME. No "internal clock" SIMs shall be
used.
If a frequency of 13/4 MHz is needed by the SIM to run the authentication procedure in the allotted time
(see TS GSM 03.20 [10]), bit 2 of byte 1 in the directory characteristics shall be set to 1. Otherwise a
minimum frequency of 13/8 MHz may be used.
The duty cycle shall be between 40% and 60% of the period during stable operation.
The ME shall operate the SIM within the following limits:

Symbol Conditions Minimum Maximum
V I = +20μA 0,7xVcc Vcc (note)
