TS.37 PRD – Requirements for Multi SIM Devices v3.0

TS.37 PRD – Requirements for Multi SIM Devices v3.0

September 21, 2017

All Documents, Terminal Steering Group

This document lays out a minimum set of requirements intended to ensure multi SIM devices show consistent behaviour. The requirements relate only to device platform elements such as hardware, protocol stack and operating systems.

In the context of this document, a multi-SIM device is any device that natively accommodates multiple SIMs. This includes

* The device has a single 3GPP/3GPP2 network connection and a single IMEI with which a single SIM selected from several within the device can be used

* The device has multiple simultaneous 3GPP/3GPP2 network connections and multiple IMEIs each of which is associated with a particular SIM.

Operations already covered by 3GPP are out of scope. While there are no explicit 3GPP specifications for multi-SIM, many of the requirements of this document build on 3GPP operations defined for single SIM cases; see below for the relevant 3GPP specifications.
