Total service revenue increased to €953.7m for the 2015/16 financial year.
This represented an €18m rise on the previous year. Its fixed-line business revenue grew particularly strongly, with a 12.3% rise to €214.7m.
Its fixed customer base increased by 17,4000 to 239,000.
Vodafone said data usage on its mobile network increased by more than 70% year-on-year.
The company’s Irish operations haemorrhaged mobile customers in the final quarter of the year, however, with 47,000 fewer people using its services at the end of March than just three months previously.
On an annual basis, the decrease was smaller at 25,000 thanks to consecutive growth each quarter up until the final quarter of the year.
As a result, the network saw its mobile customer base dip below 2m.
Vodafone Ireland CEO Anne O’Leary said:
“It’s been a strong year. The business has performed well across both mobile and fixed. The execution of our convergence strategy continues to go well, as highlighted by the launch of Vodafone TV.
“Our strategic and investment programmes for 2015/16 proceeded as planned. This included the launch of a partnership with ESB on SIRO and the introduction of LightSpeed Broadband.
“We completed these programmes while continuing to ensure that our customers received best-in-class mobile network performance.”
SIRO, which delivers 100% fibre to homes and businesses, is considered one of the frontrunners to secure the contract for the National Broadband Plan.
In November 2015, Vodafone launched LightSpeed Broadband utilising SIRO’s network to provide access to 1GB fibre broadband.
The company also invested €60m to establish a new European sales centre in Carrickmines, Co Dublin, with the creation of 200 jobs. A further €7m was invested in new data centre services as part of an expansion of its cloud and hosting business.
“Over the past 15 years, Vodafone Ireland has invested €1bn in our network and services and plans to invest in excess of €200m across, fixed, mobile and in our IT transformation programme.
"In 2016/17, we will continue to invest, listen to what our customers want and be a pioneer in network performance. Our vision is that Ireland should be a gigabit society, where there is even faster and more reliable connectivity right across the country no matter where your location,” Ms O’Leary said.
