BANGALORE, April 23 (Reuters) - Latin American wireless carrier NII Holdings Inc (NIHD.O: Quote, Profile, Research) posted better-than-expected quarterly earnings, helped by a 28 percent rise in its subscriber base, and retained its 2009 revenue outlook, sending its shares up as much as 13 percent.

The company -- which targets business customers in Mexico, Brazil, Argentina, Peru and Chile under the Nextel brand -- added more subscribers despite facing currency and economic issues in Mexico and Argentina.

The gross subscriber additions meant demand for NII's services remained strong, Stifel Nicolaus analyst Christopher King said.

"The differentiation is still there. They continue to take market share from their competitors," King added.
