1 Introduction

1.1 Overview
The aim of the GSMA Multi SIM DUTs (Device Under Test) work is to ensure all DUTs
supporting multiple SIMs behave in a similar way.

This document provides test cases for the Multi SIM requirements detailed in GSMA PRD
TS.37 Requirements for Multi SIM devices [1].

1.2 Scope
This document is intended for:

 Parties which develop test tools and platforms

 Test Labs / Test Houses which execute the testing
 Vendors, device & chipset Manufacturers
 Operators

The Test Book consists of a set of test cases relevant for testing a device supporting multiple
SIMs.

The test cases specified within the Test Book are either specified fully, step by step or refer to
existing publicly available test standards. For the test cases from other organizations, a unique
reference to the specification and test case is provided.

For each test case specified or defined by reference within this Test Book, there is a reference
to one or more requirements from the GSMA PRD TS.37 [1].

1.3 Definition of Terms

GSM Association Non-confidential
Official Document TS.42 - Multi SIM Devices Requirements Test Cases

3 Test process

3.1 Test Environment

Test cases may be performed in a Laboratory using one or more network simulators or on
Live Networks. Most tests can be performed in either environment.

For some of the test cases it is necessary to log the signalling between the DUT and the
network. If a network simulator is used all the signalling between the DUT and the network
shall be logged and shall be accessible to be used to derive the test case verdict.
If a Live Network is used, other options such as on-DUT logging or live network logging may
be used. Such logging will be implementation dependent.

The number of SIMs required for each test case depends on the capability of the DUT. Most
current DUTs require two SIMs, but some have more. Each SIM port is identified SIM n.

For each SIM, the DUT will provide a SIM slot or soldered (fix mounted) SIM (UICC). For
testing, the SIM(s) can be real physical SIMs or simulated SIMs. The SIMs can be either
Test SIMs or real according to the configuration required.

3.2 Pass Criteria

 A test is considered as successful only if the entire test procedure was carried out
successfully and the expected results observed.
 A test is considered as failed if the tested feature shows unexpected behaviour.
 A test is considered as non-conclusive when the pass criteria cannot be evaluated
due to issues during the setup of the initial conditions.

3.3 Future Study

Some of the test cases described in this Test Book are FFS (For Future Study). This means
that some clarifications are expected at the requirement level to conclude on a test method,
or that the test cases are low priority and have not yet been defined.

3.4 Tests From Other Sources

This document refers to test specifications developed by other organisations. These
organisations define their own requirements for test benches, test applicability and pass
criteria.

Changes to all tests in this document may be requested by contacting the GSMA Terminal
Steering Group at terminals@gsma.com. If such a request affects a test belonging to an
outside organisation then either:

a) The change request will be passed on to the outside organisation for action, or
b) The change request will be actioned by removing the outside reference and
drafting a replacement case within this document.

The complete Annex B only applies to handsets being tested for CCSA All Mode
certification, and covers only technologies appropriate to that market. A subset of CCSA

V2.0 Page 14 of 90
GSM Association Non-confidential
Official Document TS.42 - Multi SIM Devices Requirements Test Cases

requirements & test cases are used by GSMA TS.37 & TS.42. The GSMA documents are
global specifications wherein choice of technologies is at the discretion of the device vendor.
Hence for GSMA testing, references to Annex section 4.8.1 table 1 should be replaced with
technology combinations appropriate to the capabilities of the device under test.

3.5 Test Execution Optimisation

Some tests do not require the device to start in a powered off state. These tests may be run
directly after another test case, subject to all initial conditions for the test being met,

Annex B (Informative) English translation of YDT 3041-2016 [17]

test cases
GSMA would like to thank CCSA for providing this translation.

This annex contains an English language translation of section 4 of the Chinese All Mode
test cases document (YDT 3041-2016). This defines all test cases for All Mode operation; to
avoid duplication of effort, these test cases are extensively referenced in this GSMA
document. The English language version of YDT 3041-2016 will be formally issued by CCSA
in late 2018 – this annex will be removed once the official English language version is
available direct from CCSA. Section numbers from the original document have been retained
for clarity – test case numbers align to these.

Note: This section is informative – unless used by a specific test case in the main part
of TS.42, items within this annex are only applicable to the Chinese market.
Terminology and abbreviations in this Annex may not be aligned with other sections
in TS.42.

This complete annex only applies to devices being tested for CCSA All Mode
certification, and covers only technologies appropriate to that market. A subset of
CCSA requirements & test cases are used by GSMA TS.37 & TS.42. The GSMA
documents are global specifications wherein choice of technologies is at the
discretion of the device vendor. Hence for GSMA testing, references to Annex section
4.8.1 table 1 should be replaced with technology combinations appropriate to the
capabilities of the device under test.

Test number 4.8.7.2

Test item: network selection function
Test sub-item: selection of operator's network in standby mode
Purpose: verify the function of selecting the operator's network when the DUT is in standby
mode
Prerequisites:
The tested SIMs should meet the requirements of the corresponding SIM combination
listed in Table 1.Table 1 Requirements on SIM combinations for UEs in dual-SIM
state1
One DUT that slots and network mode have not been set.
Steps:

Expected results:
1. The DUT displays a list of the available network modes respectively for the two SIMs,
which allows the user to reselect the network.
2. If the user selects the current network for either SIM, the UE shall directly return to
standby state and shall not perform network re-selection.
3. When the UE fails to find the network operator selected by a user, it shall provide the
network list again so that the user can re-select the network.
