ATSI Revenues Increase 182%

SAN ANTONIO, TX -- (MARKET WIRE) -- November 8, 2006 -- ATSI Communications, Inc. (OTCBB: ATSX) announced today that the Company's revenues for the three months ended October 31, 2006 reached $6,540,000, a 182% improvement over revenues for the three months ended October 31, 2005. As a result, the Company expects to report its 9th consecutive quarter of record revenues that exceeded the immediately preceding quarter by $1.2 million. In addition to record revenue, the Company produced a second consecutive quarter of positive cash flow from operations and anticipates reporting positive net income for the 1st quarter ended October 31, 2006 when adjusted for non-cash and long-term incentive compensation for employees and directors. ATSI's future financial results will continue to reflect the Company's adoption of SFAS 123R accounting for the amortization expense of stock option grants.

ATSI President and CEO, Arthur L. Smith, stated, "Our track record of successful execution has continued into our current fiscal year as evidenced by record revenues and cash flow from operations. We continue to experience a global demand for our international VoIP product as traditional carriers migrate towards VoIP and emerging VoIP service providers continue to seek reliable worldwide routes. We processed a record volume of 105 million VoIP minutes of use ("MOU") during the quarter, but it's only a sliver of the approximately 72 billion voice MOUs processed in a quarter on a worldwide basis." Mr. Smith added, "In addition, management's continued commitment to profitable revenue growth combined with rigorous expense controls resulted in the second consecutive quarter of positive cash flow from operations."

ATSI Communications, Inc. operates through its two wholly owned subsidiaries, Digerati Networks, Inc. and Telefamilia Communications, Inc. Digerati Networks, Inc. is a premier global VoIP carrier serving rapidly expanding markets in Asia, Europe, the Middle East, and Latin America, with an emphasis on Mexico. Through Digerati's partnerships with established foreign carriers and network operators, interconnection and service agreements, and a NexTone powered VoIP network, ATSI believes it has clear advantages over its competition. Telefamilia Communications provides specialized retail communication services that includes VoIP services to the high-growth Hispanic market in the United States. ATSI also owns a minority interest of a subsidiary in Mexico, ATSI Comunicaciones, S.A. de C.V., which operates under a 30-year government issued telecommunications license.
