Internet service provider Digiweb announced it will become the State's fifth mobile phone provider after getting approval for the 088 prefix from the telecoms regulator ComReg today.
The new service will roll out over the next 18 months and complement its broadband service. It claims it will offer services and benefits currently unavailable to Irish consumers.
MD Colm Piercy said: 'We appreciate ComReg's foresight in seeing the potential our 4G Mobile network will have in delivering new competition and better services to the Irish consumer.'
Last week the Irish firm said it will create 200 jobs over the next three years as part of its expansion plans.
The bulk of the jobs will be based at its new data and network operations centre in Blanchardstown, which opened recently.
Digiweb, which has headquarters in Dundalk, Co Louth, employs over 120 technical staff in Dundalk, Dublin, Waterford and Limerick.
