Expense Management Terms

Quick Reference Guide:

The telecommunications world – like the military – is replete with acronyms and an endless stream of abbreviated terms that serve as shorthand to those “in-the-club,” so-to-speak.  

Although this may bring comfort or validation to those within the industry, it can also serve as a reminder or signal to those new to the Telecom Expense Management TEM Industry that they are less “in-the-know” and can potentially be off-putting.  

Since these terms and industry shorthand aren’t going anywhere, we decided to create a quick reference list of terms and abbreviations you can use to navigate any telecom or mobility-related conversation. 

In this blog, let’s get started on some standard telecom terminology and acronyms that are commonly used within the TEM industry. We will compile an ongoing list over time and include within our website  as a resource that can be used primarily for Telecom Expense Management and/or MMS reference purposes.
