NII HOLDINGS ANNOUNCES STRONG RESULTS FOR
FIRST QUARTER 2010

• Consolidated operating revenues of $1.28 billion

• Consolidated operating income before depreciation and amortization, or OIBDA, of $341 million

• Net subscriber additions of 377,000

• Consolidated operating income of $213 million and consolidated net income of $48 million, or $0.29 per basic share

RESTON, Va. — April 29, 2010— NII Holdings, Inc. [NASDAQ: NIHD] today announced its consolidated financial results for the first quarter of 2010. During the quarter, the Company added 377,000 net subscribers to its network, bringing its ending subscriber base to over 7.7 million, a 20% increase in the ending subscriber base compared to the end of the first quarter of 2009. Financial results for the quarter included consolidated operating revenues of $1.28 billion, a 33% increase compared to the first quarter of 2009, and consolidated OIBDA of $341 million for the quarter, a 39% increase compared to the same period last year.

For the first quarter of 2010, the Company generated consolidated operating income of $213 million and consolidated net income of $48 million, or $0.29 per basic share. Consolidated net income for the quarter included $25 million of pretax foreign currency transaction losses primarily related to the weakening of currency exchange rates of the Brazilian Real relative to the U.S. dollar during the first quarter of 2010 compared to the fourth quarter of 2009.

The Company continued to invest in the expansion of the coverage and capacity of its networks reporting consolidated first quarter 2010 capital expenditures of $134 million, of which $85 million was invested in Brazil.

“We are off to a tremendous start for the year, delivering excellent financial and operational results highlighted by significant improvement in churn and a record level of OIBDA during the quarter,” said Steve Dussek, NII Holdings’ Chief Executive Officer. “The foundation for our first quarter results was created last year when we implemented strategies to enhance customer retention and improve the quality of our customer base. The success of these strategies is

evidenced across all of our markets, where churn levels have improved substantially when compared to the first quarter of last year. These efforts have enabled us to keep our highest value subscribers and grow our business profitably,” he added.

NII Holdings’ consolidated average monthly service revenue per subscriber (ARPU) was $47 for the first quarter of 2010, up $5 when compared to the same period last year due primarily to strengthening of local currencies. The Company also reported churn of 1.69% for the first quarter, a 42 basis point improvement over the level reported in the same period last year. Consolidated cost per gross add, or CPGA, was $278 for the first quarter 2010, up $23 relative to the first quarter 2009, but a $27 decline over the fourth quarter of last year.

“Our balanced approach to growth and profitability drove our strong financial performance as we generated a 33% increase in revenue and a 39% increase in OIBDA over the first quarter of last year” said Gokul Hemmady, NII’s Vice President and Chief Financial Officer. “Continued improvement in the economic conditions in our markets and our strong focus on customer retention resulted in solid net subscriber growth, driving a 20% increase in our consolidated subscriber base compared to the end of the first quarter of 2009. We believe that the investments that we have made and will continue to make in our business will enhance our position as one of the premier wireless providers in Latin America.”

The Company ended the quarter with approximately $3.52 billion in total long-term debt and $2.7 billion in consolidated cash and short term investments, resulting in net debt at the end of the quarter of $841 million.

In addition to the preliminary results prepared in accordance with accounting principles generally accepted in the United States (GAAP) provided throughout this press release, NII has presented consolidated OIBDA, ARPU, CPGA and Net Debt. These measures are non-GAAP financial measures and should be considered in addition to, but not as substitutes for, the information prepared in accordance with GAAP. Reconciliations from GAAP results to these non-GAAP financial measures are provided in the notes to the attached financial table.

Consolidated Operating Income Before Depreciation and Amortization

Consolidated operating income before depreciation and amortization, or OIBDA, represents operating income before depreciation and amortization expense. Consolidated OIBDA is not a measurement under accounting principles generally accepted in the United States, may not be similar to consolidated OIBDA measures of other companies and should be considered in addition to, but not as a substitute for, the information contained in our statements of operations. We believe that consolidated OIBDA provides useful information to investors because it is an indicator of operating performance, especially in a capital intensive industry such as ours, since it excludes items that are not directly attributable to ongoing business operations. Our consolidated OIBDA calculations are commonly used as some of the bases for investors, analysts and credit rating agencies to evaluate and compare the periodic and future operating performance and value of companies within the wireless telecommunications industry. Consolidated OIBDA can be reconciled to our consolidated statements of operations as follows (in millions):

Average Monthly Revenue Per Handset/Unit in Service (ARPU)

Average monthly revenue per handset/unit in service, or ARPU, is an industry term that measures service revenues, which we refer to as subscriber revenues, per period from our customers divided by the weighted average number of handsets in commercial service during that period. ARPU is not a measurement under accounting principles generally accepted in the United States, may not be similar to ARPU measures of other companies and should be considered in addition, but not as a substitute for, the information contained in our statements of operations. We believe that ARPU provides useful information concerning the appeal of our rate plans and service offerings and our performance in attracting and retaining high value customers. Other revenue includes revenues for such services as roaming, handset maintenance, cancellation fees, analog and other. ARPU can be calculated and reconciled to our consolidated statement of operations as follows (in millions, except ARPU):

Cost per Gross Add (CPGA)

Cost per gross add, or CPGA, is an industry term that is calculated by dividing our selling, marketing and handset and accessory subsidy costs, excluding costs unrelated to initial customer acquisition, by our new subscribers during the period, or gross adds. CPGA is not a measurement under accounting principles generally accepted in the United States, may not be similar to CPGA measures of other companies and should be considered in addition, but not as a substitute for, the information contained in our statements of operations. We believe CPGA is a measure of the relative cost of customer acquisition. CPGA can be calculated and reconciled to our consolidated statements of operations as follows (in millions, except CPGA):

Net Debt

Net debt represents the total face amount of our long-term debt less cash, cash equivalents and short-term investments. Net debt to consolidated operating income before depreciation and amortization represents net debt divided by consolidated operating income before depreciation and amortization. Prior to 2008, we calculated net debt as total long-term debt less cash and cash equivalents. In 2008, we added short-term investments to the items subtracted from long-term debt to calculate net debt because we concluded that our short-term investments were similar to cash and cash equivalents in terms of liquidity and should be used similarly in providing the assessment of our overall leverage in the net debt calculation. Net debt is not a measurement under accounting principles generally accepted in the United States, may not be similar to net debt measures of other companies and should be considered in addition to, but not as a substitute for, the information contained in our balance sheets. We believe that net debt and net debt to consolidated operating income before depreciation and amortization provide useful information concerning our liquidity and leverage. Net debt as of March 31, 2010 can be calculated as follows (in millions):
