Vodafone services have been restored after a power outage. The network apologised to customers earlier for the glitch.
Over 900 homes and businesses in the Fitzwilliam Square, Baggot Street and Leeson Street area were affected by the same power cut.
Phone service and Four-G were down across parts of the country, while some broadband services were also affected.
All customers are now back up and running.
Three Mobile says it was not affected by the outage.
