Record Revenue, Positive EBITDA and Operating Income Achieved in 4th Quarter -- Expects Continued Improvement in Fiscal 2007

SAN ANTONIO, TX -- (MARKET WIRE) -- October 31, 2006 -- ATSI Communications, Inc. (OTCBB: ATSX) today announced results for the three months and fiscal year ended July 31, 2006. Revenues for the 4th quarter totaled $5,335,000, a 188% increase over the previous year's 4th quarter ended July 31, 2005. Revenues for the 4th quarter exceeded the immediately preceding quarter ended April 30, 2006 by $1.24 million and resulted in the 8th consecutive quarter of record revenues for the Company since ATSI's reincorporation in May 2004. In addition, the Company reached a key profitability milestone by producing EBITDA of $22,000 and Operating Income of $2,000 for the three months ended July 31, 2006. Adjusted for non-cash expenses, the Company produced EBITDA of $134,000 for the same period.

For its fiscal year ended July 31, 2006, ATSI reported revenues of $14.7 million, a 144% increase over revenues of $6 million for the previous fiscal year ended July 31, 2005. Net loss to common stockholders for the year ended July 31, 2006 was $12,000 vs. net income to common stockholders of $9.7 million for the Company's previous year ended July 31, 2005 that included a non-cash, one-time gain of $12.1 million on disposal of an investment. In addition, the Company reported a key balance sheet improvement of $2.7 million for FY2006 as a result of reclassifying certain current liabilities to stockholder's equity during the 4th quarter.

The Company continued to meet key corporate objectives while successfully reaching internal milestones of its business model. Management believes the accomplishments during FY2006 have further strengthened the Company's foundation, thus facilitating future improvement in shareholder value.

The following is a summary of the significant achievements for the year:

--  4 consecutive quarters of record revenue since the Company's
    reincorporation:
         + 176% growth in 1st quarter
         +  94% growth in 2nd quarter
         + 128% growth in 3rd quarter
         + 188% growth in 4th quarter

--  Achieving positive cash flow and operational profitability in the 4th
    quarter

--  Net reduction of $2.1 million in liabilities

--  Formation of new subsidiary, Digerati Networks, to showcase ATSI's
    growing VoIP business

--  Expansion of Company's VoIP network by 65% with NexTone Communications
    to support future products and growth

Arthur L. Smith, CEO of ATSI, stated, "We had an incredible year that ended with the Company producing record revenues, positive EBITDA, and positive Operating Income for the 4th quarter ended July 31, 2006. This trend has continued into the 1st quarter of our current fiscal year with revenues expected to reach $6.4 million and resulting in the 9th consecutive quarter of record revenues since our reincorporation. We also anticipate additional balance sheet improvements over the next 2 quarters." Mr. Smith added, "I commend our team for successfully executing on every corporate and operational objective we set at the beginning of FY2006. Our operations team, led by Ruben Caraveo, did a tremendous job by exceeding VoIP revenue expectations during every quarter of FY2006. Although we fully expect FY2007 to be a record year in terms of revenue, we are shifting efforts towards improving our gross profit while maintaining SG&A at or near current levels. The anticipated result is increased cash flow from operations that will subsequently increase our cash reserves, improve our balance sheet, and enhance our ability to internally finance our growth."

Excluding non-cash items, net loss to common stockholders for the year ended July 31, 2006 was $63,000 vs. a net loss to common stockholders of $587,000 for the previous year ended July 31, 2005. For FY2006 the Company incurred $443,000 in non-cash compensation and warrant expense. Additional non-cash items incurred during the year include depreciation and amortization expense, interest expense, and preferred dividend expense. The Company also realized a non-cash gain of $1.7 million on disposal of operations that were discontinued.

Net loss before non-cash items is not a term defined by generally accepted accounting principles (GAAP) and may not be comparable to other similarly titled measurements used by other companies. Such non-GAAP measures should be considered in addition to, and not as a substitute for, performance measures calculated in accordance with GAAP. The accompanying table includes a detailed reconciliation of net loss reported in accordance with GAAP to net loss before non-cash items.
