Mobile contacting
This has been a typical scenario of conventional paging systems and SMS is increasingly replacing paging here. The main purpose of this application is to reach outdoor employees and field service personnel on the company campus or at the customer site discreetly and any time.  The replacement of pagers by existing mobile phones with SMS is inexpensive and quickly done. Additionally, SMS offers various technical advantages which are explained below.

Internal person-to-person communication
Most UM systems (Unified Messaging Systems) for internal communication offer SMS functionality and are used for mobile contacting or wireless person-to-person messaging. However, SMS functionality of UM system is often limited and unidirectional. Adding a powerful SMS application to the IT environment can extend the UM system, provide enough power and message throughput for large corporate applications, offer 2-way communication and set free enormous potential. It significantly increases the efficiency and application range of mobile communication.

Automated and manual alerts and escalation
SMS is perfectly suited for alerting mobile maintenance personnel. Essential for this particular scenario is the availability of third-party interfaces to embed SMS seamlessly and reliably into existing IT environments. The availability of flexible escalation mechanisms is beneficial. Thus, SMS alarms can be initiated manually or fully automated by production line monitoring or other corporate management systems.

Mobile office applications, e-mail notifications
The objective of numerous deployments of SMS and other mobile communication tools is the mobilization of existing applications and the integration of field service staff into the work and communication flow. In this regard the mobilization of office applications, especially of email, plays a basic role. The wireless notification of new, incoming e-mails is a simple but important and typical application. The notification of new appointment and calendar events is also often desired.

Group messaging
For internal team and group communication SMS is an exceptional tool. In opposition to paging systems, groups can be assigned and managed dynamically via a web user interface. Submission of messages is seamlessly integrated into an intranet website. Although there is no pager-like broadcast group transmission contemporary, SMS software can easily emulate such behavior.
