SmartSaver.ie's head-to-head comparison of Three Ireland and Vodafone Ireland. The numbers below come from SmartSaver.ie's daily price checks (as of 2026-08-17).
Ireland's two biggest networks, and the trade-off is consistent: Vodafone is the premium network with strong reliability scores and better customer-service reputation; Three is the value network with unlimited data as standard and a bigger 5G footprint. Vodafone plans typically cost more for equivalent allowances: you're paying for the network experience. If price-per-GB matters most, Three wins; if you want the network most businesses default to, Vodafone.
