Consumers have increased the use of mobile data as voice calls declined, according to the latest figures from Vodafone Ireland.
In what the mobile operator described as "a clear shift in how the nation communicates", mobile data usage rose by 19.24% year-on-year, climbing from 445,133 terabytes in 2024 to 530,794 terabytes in 2025.
The busiest day for data was December 9, when 1,660 terabytes was consumed nationwide as Storm Bram swept across Ireland.
Evenings remain Ireland's prime time for digital activity, with 10pm emerging as the busiest hour for online engagement.
While data demand continues to rise, overall voice traffic fell by 7.83% compared to 2024, reflecting a growing preference for messaging, video calls, and social platforms over traditional voice communication.
But, the festive season saw millions in Ireland pick up the phone. Christmas Day recorded almost 3.4 million calls, while New Year’s Day soared past 4.5 million.
The busiest day for calls in 2025 was March 26 with about 10 million calls of an average 3-minute duration.
Last year was also marked by "extraordinary peaks" in data usage during Ireland’s major events. During the Ireland vs South Africa rugby match, Vodafone’s network handled over 15,000 calls.
During the Dua Lipa and Lana Del Rey concerts at Aviva Stadium, Vodafone’s network reported over 5 terabytes of mobile data usage, which included the sharing of thousands of photos, live streams, and social media usage.
