Holafly adds an unlimited daily option at $2.79/day, which suits heavy data users on trips of 5+ days. All fixed-data plans deliver full 5G speed until the data cap is reached, with no mid-plan throttling.

What We Tested
We ranked 7 eSIM plans from 5 providers for Ireland across five dimensions: Coverage (25%), Pricing (25%), Speed (20%), App Quality (15%), Support (15%). Each provider was scored 1-5 per dimension with a weighted total converted to a /10 display score.
How We Scored
Scores for Ireland use our standard weighted formula: Coverage (25%), Pricing (25%), Speed (20%), App quality (15%), and Support (15%). Each dimension receives a raw score from 1 to 5. The composite multiplies by 2 for a 0-10 display scale. Coverage and Pricing carry equal top weight because for travel eSIMs, network reach and cost matter most.
Country-specific adjustments for Ireland: Single-carrier markets like Ireland receive a ceiling of 4.0/5 on Coverage, since no failover redundancy exists. Unlimited plan availability in Ireland adjusts the Pricing dimension to weight per-day unlimited rates alongside per-GB fixed rates. Widespread 5G in Ireland adds a 0.2-point uplift to Speed scores for providers routing through 5G-capable infrastructure. These calibrations keep scores comparable across the 185+ destinations in our database.
The scoring spread across 5 providers for Ireland is 1.5 points (HelloRoam at 9.5/10 down to Nomad at 8.0/10).
