AT&T Wireless: Text Messaging

This case examines AT&T’s wireless business with a focus on its text messaging services. The industry features a high proportion of fixed costs in relation to acquiring spectrum and building a network. Variable costs are relatively low, especially in the case of SMS text messages. Pricing and margins in text messaging have attracted regulatory scrutiny in the Unites States, Canada, and elsewhere. The case requires the use of key concepts in cost behaviour, cost volume profit analysis, and product costing to understand the nature of the business and the profit margins involved. Many service or high-tech businesses exhibit similar cost behaviours, and so the case gives students insight into the management of such enterprises.
