Ireland: Mobile Coverage & Carriers
Ireland's mobile market is served by three major carriers: Vodafone, Three, and Eir. All three networks support 3G and 4G/LTE services commercially. 5G has also been commercially launched in the country. Roaming eSIMs typically connect via LTE bands B20 (800 MHz), B3 (1800 MHz), and B7 (2600 MHz), with 5G connectivity on band n78 (3.5 GHz).
Local Irish carriers issue eSIMs, making it straightforward for users to activate service on compatible devices. This option provides flexibility for both residents and visitors requiring mobile connectivity across the island.
