SANTIAGO, April 29 (Reuters) - Chilean telecoms firm Entel said on Tuesday that it planned to invest $2.8 bln over the next three years to develop its network for high-speed 3G and 4G mobile technology in Chile and Peru.
The company said at its annual general meeting that $2.1 billion of those funds were earmarked for its home country, where it is the largest mobile phone operator.
It was evaluating issuing around $600 million of debt this year, it added.
Entel has enjoyed double-digit revenue growth in recent years, with sales of over $3 billion in 2013. (Reporting by Antonio de la Jara, Editing by Franklin Paul and David Gregorio)
