> 1 | Introduction

> Because of the breadth of capabilities and features of the Siemens AG GSM/GPRS Module (further referred to as the Module), it can be difficult for the customer to design interfaces and choose suitable command sequences when implementing an application e.g. the MMI of an application.
> Thus, many customers have found it helpful to be provided with advice on command sequences and proposals for small implementations.
> This document is intended to provide exactly this help and make the startup of an MMI implementation much easier. Examples and useful descriptions have been included and will be continuously enhanced according to the customers’ requirements.
