Up to 50 jobs could be created as Carphone Warehouse opens a data centre to support the roll-out of its new mobile operator service next year.
The mobile service will launch in July and targets 6% of the market within the first five years.
The data centre - which will officially open in January in Citywest in Dublin - will house the infrastructure to develop and run the service.
The total investment is worth €30m and will lead to the creation of up to 50 full-time jobs, as well as indirect employment through partnerships.
Carphone Warehouse has 91 retail outlets across Ireland and is the country's biggest independent communications retailer.
It employs over 700 people.
