May 4 (Reuters) - Syniverse Holdings Inc SVR.N, which provides technology services to wireless telecom companies, posted a higher quarterly profit helped by strength in its roaming and messaging lines of business, and raised its revenue outlook for 2010.

First-quarter net income increased to $19.7 million, or 29 cents per share, from $16 million, or 23 cents per share a year earlier. Excluding items, Syniverse posted earnings of 45 cents a share.

Revenue rose 36.8 percent to $149 million.

Analysts on average had expected earnings of 41 cents a share, excluding exceptional items, on revenue of $142.8 million, according to Thomson Reuters I/B/E/S.

Adjusted earnings before interest, tax, depreciation and amortization (EBITDA) rose 30.3 percent to $61.5 million.

Messaging services revenues were $47.4 million compared with $9.4 million a year ago. The increase was driven by the company's messaging acquisition, which contributed $41.8 million of revenue in the quarter.

On Oct. 23, Syniverse completed the acquisition of VeriSign's (VRSN.O) mobile messaging business for about $175 million in cash.

The company now expects full-year 2010 revenue of $605 million to $625 million, up from prior expectations of $590 million to $620 million. It expects adjusted EBITDA of $249 million to $260 million.

Analysts were looking for revenue of $611 million.

Shares of the Tampa, Florida-based company were up 5 percent at $20.48 in trading after the bell. They closed at $19.54 Tuesday on the New York Stock Exchange. (Reporting by Shrutika Verma in Bangalore; Editing by Don Sebastian)
