Vodafone has said its mobile customer numbers in Ireland fell in the three months to the end of June.
In a trading update, the company said it has 2,129,000 customers at the end of June, a drop of 46,000 from the figure three months earlier.
The average monthly revenue from Irish customers in the period was €38.60, a drop of 7.4% from the same quarter last year.
Vodafone, the world's largest mobile phone firm, reported total sales in line with market expectations for the quarter as strength in India and Africa compensated for weakness in Europe.
The group reiterated its reduced full-year outlook for, at best, flat profits. It has not given a precise figure for full-year revenue.
In the quarter, group revenue rose 9.3% from a year earlier to £10.74 billion, thanks to positive currency effects and a higher stake in South Africa's Vodacom.
Revenue fell in Spain and Britain, as expected, and also fell 4.8% in Germany, driven by cuts in mobile termination charges, reduced roaming as tourists and business people cut down on travel and lower spending by pre-paid customers.
Vodafone added eight million customers in the quarter, taking its proportionate customer base to 315 million. Vodafone's data revenue grew 19% organically to £888m.
