Mobile operator Three Ireland has recorded a 4% increase in earnings in the first half of 2019, driven by a growing customer base.

The company's earnings before interest, tax, depreciation and amortization (EBITA) grew to €98m in the first six months of the year, up from €94m in the same period last year.

Three grew its active customer base by 7% to 2.3 million over the same period, an increase of about 200,000 customers, while the company's revenue increased by 2%.

Robert Finnegan, CEO of Three Ireland, said: "The strength of our network and the quality of our customer service continues to attract new customers to Three."

"Three Ireland has an average monthly churn rate of 1% for contract customers, which is a testament to the enhanced customer experience we have delivered and our continued investment in our network and digital transformation programme".

The company says overall data traffic on its network has increased by 43% year-on-year, and that it  carried almost two thirds of the country's total mobile data in the first quarter of 2019.
